+The Yocto Project Test Environment Manual
+*****************************************
+
+.. _test-welcome:
+
+Welcome
+=======
+
+Welcome to the Yocto Project Test Environment Manual! This manual is a
+work in progress. The manual contains information about the testing
+environment used by the Yocto Project to make sure each major and minor
+release works as intended. All the project's testing infrastructure and
+processes are publicly visible and available so that the community can
+see what testing is being performed, how it's being done and the current
+status of the tests and the project at any given time. It is intended
+that Other organizations can leverage off the process and testing
+environment used by the Yocto Project to create their own automated,
+production test environment, building upon the foundations from the
+project core.
+
+Currently, the Yocto Project Test Environment Manual has no projected
+release date. This manual is a work-in-progress and is being initially
+loaded with information from the README files and notes from key
+engineers:
+
+- *yocto-autobuilder2:* This
+ :yocto_git:`README.md </cgit.cgi/yocto-autobuilder2/tree/README.md>`
+ is the main README which detials how to set up the Yocto Project
+ Autobuilder. The ``yocto-autobuilder2`` repository represents the
+ Yocto Project's console UI plugin to Buildbot and the configuration
+ necessary to configure Buildbot to perform the testing the project
+ requires.
+
+- *yocto-autobuilder-helper:* This :yocto_git:`README </cgit.cgi/yocto-autobuilder-helper/tree/README/>`
+ and repository contains Yocto Project Autobuilder Helper scripts and
+ configuration. The ``yocto-autobuilder-helper`` repository contains
+ the "glue" logic that defines which tests to run and how to run them.
+ As a result, it can be used by any Continuous Improvement (CI) system
+ to run builds, support getting the correct code revisions, configure
+ builds and layers, run builds, and collect results. The code is
+ independent of any CI system, which means the code can work `Buildbot <https://docs.buildbot.net/0.9.15.post1/>`__,
+ Jenkins, or others. This repository has a branch per release of the
+ project defining the tests to run on a per release basis.
+
+.. _test-yocto-project-autobuilder-overview:
+
+Yocto Project Autobuilder Overview
+==================================
+
+The Yocto Project Autobuilder collectively refers to the software,
+tools, scripts, and procedures used by the Yocto Project to test
+released software across supported hardware in an automated and regular
+fashion. Basically, during the development of a Yocto Project release,
+the Autobuilder tests if things work. The Autobuilder builds all test
+targets and runs all the tests.
+
+The Yocto Project uses now uses standard upstream
+`Buildbot <https://docs.buildbot.net/0.9.15.post1/>`__ (version 9) to
+drive its integration and testing. Buildbot Nine has a plug-in interface
+that the Yocto Project customizes using code from the
+``yocto-autobuilder2`` repository, adding its own console UI plugin. The
+resulting UI plug-in allows you to visualize builds in a way suited to
+the project's needs.
+
+A ``helper`` layer provides configuration and job management through
+scripts found in the ``yocto-autobuilder-helper`` repository. The
+``helper`` layer contains the bulk of the build configuration
+information and is release-specific, which makes it highly customizable
+on a per-project basis. The layer is CI system-agnostic and contains a
+number of Helper scripts that can generate build configurations from
+simple JSON files.
+
+.. note::
+
+ The project uses Buildbot for historical reasons but also because
+ many of the project developers have knowledge of python. It is
+ possible to use the outer layers from another Continuous Integration
+ (CI) system such as
+ `Jenkins <https://en.wikipedia.org/wiki/Jenkins_(software)>`__
+ instead of Buildbot.
+
+The following figure shows the Yocto Project Autobuilder stack with a
+topology that includes a controller and a cluster of workers:

+
+.. _test-project-tests:
+
+Yocto Project Tests - Types of Testing Overview
+===============================================
+
+The Autobuilder tests different elements of the project by using
+thefollowing types of tests:
+
+- *Build Testing:* Tests whether specific configurations build by
+ varying :term:`MACHINE`,
+ :term:`DISTRO`, other configuration
+ options, and the specific target images being built (or world). Used
+ to trigger builds of all the different test configurations on the
+ Autobuilder. Builds usually cover many different targets for
+ different architectures, machines, and distributions, as well as
+ different configurations, such as different init systems. The
+ Autobuilder tests literally hundreds of configurations and targets.
+
+ - *Sanity Checks During the Build Process:* Tests initiated through
+ the :ref:`insane <ref-classes-insane>`
+ class. These checks ensure the output of the builds are correct.
+ For example, does the ELF architecture in the generated binaries
+ match the target system? ARM binaries would not work in a MIPS
+ system!
+
+- *Build Performance Testing:* Tests whether or not commonly used steps
+ during builds work efficiently and avoid regressions. Tests to time
+ commonly used usage scenarios are run through ``oe-build-perf-test``.
+ These tests are run on isolated machines so that the time
+ measurements of the tests are accurate and no other processes
+ interfere with the timing results. The project currently tests
+ performance on two different distributions, Fedora and Ubuntu, to
+ ensure we have no single point of failure and can ensure the
+ different distros work effectively.
+
+- *eSDK Testing:* Image tests initiated through the following command::
+
+ $ bitbake image -c testsdkext
+
+ The tests utilize the ``testsdkext`` class and the ``do_testsdkext`` task.
+
+- *Feature Testing:* Various scenario-based tests are run through the
+ :ref:`OpenEmbedded Self test (oe-selftest) <ref-manual/ref-release-process:Testing and Quality Assurance>`. We test oe-selftest on each of the main distrubutions
+ we support.
+
+- *Image Testing:* Image tests initiated through the following command::
+
+ $ bitbake image -c testimage
+
+ The tests utilize the :ref:`testimage* <ref-classes-testimage*>`
+ classes and the :ref:`ref-tasks-testimage` task.
+
+- *Layer Testing:* The Autobuilder has the possibility to test whether
+ specific layers work with the test of the system. The layers tested
+ may be selected by members of the project. Some key community layers
+ are also tested periodically.
+
+- *Package Testing:* A Package Test (ptest) runs tests against packages
+ built by the OpenEmbedded build system on the target machine. See the
+ :ref:`Testing Packages With
+ ptest <dev-manual/dev-manual-common-tasks:Testing Packages With ptest>` section
+ in the Yocto Project Development Tasks Manual and the
+ ":yocto_wiki:`Ptest </wiki/Ptest>`" Wiki page for more
+ information on Ptest.
+
+- *SDK Testing:* Image tests initiated through the following command::
+
+ $ bitbake image -c testsdk
+
+ The tests utilize the :ref:`testsdk <ref-classes-testsdk>` class and
+ the ``do_testsdk`` task.
+
+- *Unit Testing:* Unit tests on various components of the system run
+ through :ref:`bitbake-selftest <ref-manual/ref-release-process:Testing and Quality Assurance>` and
+ :ref:`oe-selftest <ref-manual/ref-release-process:Testing and Quality Assurance>`.
+
+- *Automatic Upgrade Helper:* This target tests whether new versions of
+ software are available and whether we can automatically upgrade to
+ those new versions. If so, this target emails the maintainers with a
+ patch to let them know this is possible.
+
+.. _test-test-mapping:
+
+How Tests Map to Areas of Code
+==============================
+
+Tests map into the codebase as follows:
+
+- *bitbake-selftest:*
+
+ These tests are self-contained and test BitBake as well as its APIs,
+ which include the fetchers. The tests are located in
+ ``bitbake/lib/*/tests``.
+
+ From within the BitBake repository, run the following::
+
+ $ bitbake-selftest
+
+ To skip tests that access the Internet, use the ``BB_SKIP_NETTEST``
+ variable when running "bitbake-selftest" as follows::
+
+ $ BB_SKIP_NETTEST=yes bitbake-selftest
+
+ The default output is quiet and just prints a summary of what was
+ run. To see more information, there is a verbose option::
+
+ $ bitbake-selftest -v
+
+ Use this option when you wish to skip tests that access the network,
+ which are mostly necessary to test the fetcher modules. To specify
+ individual test modules to run, append the test module name to the
+ "bitbake-selftest" command. For example, to specify the tests for the
+ bb.data.module, run::
+
+ $ bitbake-selftest bb.test.data.module
+
+ You can also specify individual tests by defining the full name and module
+ plus the class path of the test, for example::
+
+ $ bitbake-selftest bb.tests.data.TestOverrides.test_one_override
+
+ The tests are based on `Python
+ unittest <https://docs.python.org/3/library/unittest.html>`__.
+
+- *oe-selftest:*
+
+ - These tests use OE to test the workflows, which include testing
+ specific features, behaviors of tasks, and API unit tests.
+
+ - The tests can take advantage of parallelism through the "-j"
+ option, which can specify a number of threads to spread the tests
+ across. Note that all tests from a given class of tests will run
+ in the same thread. To parallelize large numbers of tests you can
+ split the class into multiple units.
+
+ - The tests are based on Python unittest.
+
+ - The code for the tests resides in
+ ``meta/lib/oeqa/selftest/cases/``.
+
+ - To run all the tests, enter the following command::
+
+ $ oe-selftest -a
+
+ - To run a specific test, use the following command form where
+ testname is the name of the specific test::
+
+ $ oe-selftest -r <testname>
+
+ For example, the following command would run the tinfoil
+ getVar API test::
+
+ $ oe-selftest -r tinfoil.TinfoilTests.test_getvar
+
+ It is also possible to run a set
+ of tests. For example the following command will run all of the
+ tinfoil tests::
+
+ $ oe-selftest -r tinfoil
+
+- *testimage:*
+
+ - These tests build an image, boot it, and run tests against the
+ image's content.
+
+ - The code for these tests resides in ``meta/lib/oeqa/runtime/cases/``.
+
+ - You need to set the :term:`IMAGE_CLASSES` variable as follows::
+
+ IMAGE_CLASSES += "testimage"
+
+ - Run the tests using the following command form::
+
+ $ bitbake image -c testimage
+
+- *testsdk:*
+
+ - These tests build an SDK, install it, and then run tests against
+ that SDK.
+
+ - The code for these tests resides in ``meta/lib/oeqa/sdk/cases/``.
+
+ - Run the test using the following command form::
+
+ $ bitbake image -c testsdk
+
+- *testsdk_ext:*
+
+ - These tests build an extended SDK (eSDK), install that eSDK, and
+ run tests against the eSDK.
+
+ - The code for these tests resides in ``meta/lib/oeqa/esdk``.
+
+ - To run the tests, use the following command form::
+
+ $ bitbake image -c testsdkext
+
+- *oe-build-perf-test:*
+
+ - These tests run through commonly used usage scenarios and measure
+ the performance times.
+
+ - The code for these tests resides in ``meta/lib/oeqa/buildperf``.
+
+ - To run the tests, use the following command form::
+
+ $ oe-build-perf-test <options>
+
+ The command takes a number of options,
+ such as where to place the test results. The Autobuilder Helper
+ Scripts include the ``build-perf-test-wrapper`` script with
+ examples of how to use the oe-build-perf-test from the command
+ line.
+
+ Use the ``oe-git-archive`` command to store test results into a
+ Git repository.
+
+ Use the ``oe-build-perf-report`` command to generate text reports
+ and HTML reports with graphs of the performance data. For
+ examples, see
+ :yocto_dl:`/releases/yocto/yocto-2.7/testresults/buildperf-centos7/perf-centos7.yoctoproject.org_warrior_20190414204758_0e39202.html`
+ and
+ :yocto_dl:`/releases/yocto/yocto-2.7/testresults/buildperf-centos7/perf-centos7.yoctoproject.org_warrior_20190414204758_0e39202.txt`.
+
+ - The tests are contained in ``lib/oeqa/buildperf/test_basic.py``.
+
+Test Examples
+=============
+
+This section provides example tests for each of the tests listed in the
+:ref:`test-manual/test-manual-intro:How Tests Map to Areas of Code` section.
+
+For oeqa tests, testcases for each area reside in the main test
+directory at ``meta/lib/oeqa/selftest/cases`` directory.
+
+For oe-selftest. bitbake testcases reside in the ``lib/bb/tests/``
+directory.
+
+.. _bitbake-selftest-example:
+
+``bitbake-selftest``
+--------------------
+
+A simple test example from ``lib/bb/tests/data.py`` is::
+
+ class DataExpansions(unittest.TestCase):
+ def setUp(self):
+ self.d = bb.data.init()
+ self.d["foo"] = "value_of_foo"
+ self.d["bar"] = "value_of_bar"
+ self.d["value_of_foo"] = "value_of_'value_of_foo'"
+
+ def test_one_var(self):
+ val = self.d.expand("${foo}")
+ self.assertEqual(str(val), "value_of_foo")
+
+In this example, a ``DataExpansions`` class of tests is created,
+derived from standard python unittest. The class has a common ``setUp``
+function which is shared by all the tests in the class. A simple test is
+then added to test that when a variable is expanded, the correct value
+is found.
+
+Bitbake selftests are straightforward python unittest. Refer to the
+Python unittest documentation for additional information on writing
+these tests at: https://docs.python.org/3/library/unittest.html.
+
+.. _oe-selftest-example:
+
+``oe-selftest``
+---------------
+
+These tests are more complex due to the setup required behind the scenes
+for full builds. Rather than directly using Python's unittest, the code
+wraps most of the standard objects. The tests can be simple, such as
+testing a command from within the OE build environment using the
+following example::
+
+ class BitbakeLayers(OESelftestTestCase):
+ def test_bitbakelayers_showcrossdepends(self):
+ result = runCmd('bitbake-layers show-cross-depends')
+ self.assertTrue('aspell' in result.output, msg = "No dependencies were shown. bitbake-layers show-cross-depends output: %s"% result.output)
+
+This example, taken from ``meta/lib/oeqa/selftest/cases/bblayers.py``,
+creates a testcase from the ``OESelftestTestCase`` class, derived
+from ``unittest.TestCase``, which runs the ``bitbake-layers`` command
+and checks the output to ensure it contains something we know should be
+here.
+
+The ``oeqa.utils.commands`` module contains Helpers which can assist
+with common tasks, including:
+
+- *Obtaining the value of a bitbake variable:* Use
+ ``oeqa.utils.commands.get_bb_var()`` or use
+ ``oeqa.utils.commands.get_bb_vars()`` for more than one variable
+
+- *Running a bitbake invocation for a build:* Use
+ ``oeqa.utils.commands.bitbake()``
+
+- *Running a command:* Use ``oeqa.utils.commandsrunCmd()``
+
+There is also a ``oeqa.utils.commands.runqemu()`` function for launching
+the ``runqemu`` command for testing things within a running, virtualized
+image.
+
+You can run these tests in parallel. Parallelism works per test class,
+so tests within a given test class should always run in the same build,
+while tests in different classes or modules may be split into different
+builds. There is no data store available for these tests since the tests
+launch the ``bitbake`` command and exist outside of its context. As a
+result, common bitbake library functions (bb.\*) are also unavailable.
+
+.. _testimage-example:
+
+``testimage``
+-------------
+
+These tests are run once an image is up and running, either on target
+hardware or under QEMU. As a result, they are assumed to be running in a
+target image environment, as opposed to a host build environment. A
+simple example from ``meta/lib/oeqa/runtime/cases/python.py`` contains
+the following::
+
+ class PythonTest(OERuntimeTestCase):
+ @OETestDepends(['ssh.SSHTest.test_ssh'])
+ @OEHasPackage(['python3-core'])
+ def test_python3(self):
+ cmd = "python3 -c \\"import codecs; print(codecs.encode('Uryyb, jbeyq', 'rot13'))\""
+ status, output = self.target.run(cmd)
+ msg = 'Exit status was not 0. Output: %s' % output
+ self.assertEqual(status, 0, msg=msg)
+
+In this example, the ``OERuntimeTestCase`` class wraps
+``unittest.TestCase``. Within the test, ``self.target`` represents the
+target system, where commands can be run on it using the ``run()``
+method.
+
+To ensure certain test or package dependencies are met, you can use the
+``OETestDepends`` and ``OEHasPackage`` decorators. For example, the test
+in this example would only make sense if python3-core is installed in
+the image.
+
+.. _testsdk_ext-example:
+
+``testsdk_ext``
+---------------
+
+These tests are run against built extensible SDKs (eSDKs). The tests can
+assume that the eSDK environment has already been setup. An example from
+``meta/lib/oeqa/sdk/cases/devtool.py`` contains the following::
+
+ class DevtoolTest(OESDKExtTestCase):
+ @classmethod def setUpClass(cls):
+ myapp_src = os.path.join(cls.tc.esdk_files_dir, "myapp")
+ cls.myapp_dst = os.path.join(cls.tc.sdk_dir, "myapp")
+ shutil.copytree(myapp_src, cls.myapp_dst)
+ subprocess.check_output(['git', 'init', '.'], cwd=cls.myapp_dst)
+ subprocess.check_output(['git', 'add', '.'], cwd=cls.myapp_dst)
+ subprocess.check_output(['git', 'commit', '-m', "'test commit'"], cwd=cls.myapp_dst)
+
+ @classmethod
+ def tearDownClass(cls):
+ shutil.rmtree(cls.myapp_dst)
+ def _test_devtool_build(self, directory):
+ self._run('devtool add myapp %s' % directory)
+ try:
+ self._run('devtool build myapp')
+ finally:
+ self._run('devtool reset myapp')
+ def test_devtool_build_make(self):
+ self._test_devtool_build(self.myapp_dst)
+
+In this example, the ``devtool``
+command is tested to see whether a sample application can be built with
+the ``devtool build`` command within the eSDK.
+
+.. _testsdk-example:
+
+``testsdk``
+-----------
+
+These tests are run against built SDKs. The tests can assume that an SDK
+has already been extracted and its environment file has been sourced. A
+simple example from ``meta/lib/oeqa/sdk/cases/python2.py`` contains the
+following::
+
+ class Python3Test(OESDKTestCase):
+ def setUp(self):
+ if not (self.tc.hasHostPackage("nativesdk-python3-core") or
+ self.tc.hasHostPackage("python3-core-native")):
+ raise unittest.SkipTest("No python3 package in the SDK")
+
+ def test_python3(self):
+ cmd = "python3 -c \\"import codecs; print(codecs.encode('Uryyb, jbeyq', 'rot13'))\""
+ output = self._run(cmd)
+ self.assertEqual(output, "Hello, world\n")
+
+In this example, if nativesdk-python3-core has been installed into the SDK, the code runs
+the python3 interpreter with a basic command to check it is working
+correctly. The test would only run if python3 is installed in the SDK.
+
+.. _oe-build-perf-test-example:
+
+``oe-build-perf-test``
+----------------------
+
+The performance tests usually measure how long operations take and the
+resource utilisation as that happens. An example from
+``meta/lib/oeqa/buildperf/test_basic.py`` contains the following::
+
+ class Test3(BuildPerfTestCase):
+ def test3(self):
+ """Bitbake parsing (bitbake -p)"""
+ # Drop all caches and parse
+ self.rm_cache()
+ oe.path.remove(os.path.join(self.bb_vars['TMPDIR'], 'cache'), True)
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_1',
+ 'bitbake -p (no caches)')
+ # Drop tmp/cache
+ oe.path.remove(os.path.join(self.bb_vars['TMPDIR'], 'cache'), True)
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_2',
+ 'bitbake -p (no tmp/cache)')
+ # Parse with fully cached data
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_3',
+ 'bitbake -p (cached)')
+
+This example shows how three specific parsing timings are
+measured, with and without various caches, to show how BitBake's parsing
+performance trends over time.
+
+.. _test-writing-considerations:
+
+Considerations When Writing Tests
+=================================
+
+When writing good tests, there are several things to keep in mind. Since
+things running on the Autobuilder are accessed concurrently by multiple
+workers, consider the following:
+
+**Running "cleanall" is not permitted.**
+
+This can delete files from DL_DIR which would potentially break other
+builds running in parallel. If this is required, DL_DIR must be set to
+an isolated directory.
+
+**Running "cleansstate" is not permitted.**
+
+This can delete files from SSTATE_DIR which would potentially break
+other builds running in parallel. If this is required, SSTATE_DIR must
+be set to an isolated directory. Alternatively, you can use the "-f"
+option with the ``bitbake`` command to "taint" tasks by changing the
+sstate checksums to ensure sstate cache items will not be reused.
+
+**Tests should not change the metadata.**
+
+This is particularly true for oe-selftests since these can run in
+parallel and changing metadata leads to changing checksums, which
+confuses BitBake while running in parallel. If this is necessary, copy
+layers to a temporary location and modify them. Some tests need to
+change metadata, such as the devtool tests. To prevent the metadate from
+changes, set up temporary copies of that data first.

+ <para> Welcome to the Yocto Project Test Environment Manual! This manual is a work in
+ progress. The manual contains information about the testing environment used by the
+ Yocto Project to make sure each major and minor release works as intended. All the
+ project's testing infrastructure and processes are publicly visible and available so
+ that the community can see what testing is being performed, how it's being done and the
+ current status of the tests and the project at any given time. It is intended that Other
+ organizations can leverage off the process and testing environment used by the Yocto
+ Project to create their own automated, production test environment, building upon the
+ foundations from the project core. </para>

+
+ <para>The Yocto Project Autobuilder collectively refers to the software, tools, scripts, and
+ procedures used by the Yocto Project to test released software across supported hardware
+ in an automated and regular fashion. Basically, during the development of a Yocto
+ Project release, the Autobuilder tests if things work. The Autobuilder builds all test
+ targets and runs all the tests. </para>
+
+ <para>The Yocto Project uses now uses standard upstream <ulink
+ url="https://docs.buildbot.net/0.9.15.post1/">Buildbot</ulink> (version 9) to drive
+ its integration and testing. Buildbot Nine has a plug-in interface that the Yocto
+ Project customizes using code from the <filename>yocto-autobuilder2</filename>
+ repository, adding its own console UI plugin. The resulting UI plug-in allows you to
+ visualize builds in a way suited to the project's needs.</para>
+
+ <para>A <filename>helper</filename> layer provides configuration and job management through
+ scripts found in the <filename>yocto-autobuilder-helper</filename> repository. The
+ <filename>helper</filename> layer contains the bulk of the build configuration
+ information and is release-specific, which makes it highly customizable on a per-project
+ basis. The layer is CI system-agnostic and contains a number of Helper scripts that can
+ generate build configurations from simple JSON files. <note>
+ <para>The project uses Buildbot for historical reasons but also because many of the
+ project developers have knowledge of python. It is possible to use the outer
+ layers from another Continuous Integration (CI) system such as <ulink

+ <para>The performance tests usually measure how long operations take and the resource
+ utilisation as that happens. An example from
+ <filename>meta/lib/oeqa/buildperf/test_basic.py</filename> contains the
+ following:<literallayout class="monospaced">
+ class Test3(BuildPerfTestCase):
+
+ def test3(self):
+ """Bitbake parsing (bitbake -p)"""
+ # Drop all caches and parse
+ self.rm_cache()
+ oe.path.remove(os.path.join(self.bb_vars['TMPDIR'], 'cache'), True)
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_1',
+ 'bitbake -p (no caches)')
+ # Drop tmp/cache
+ oe.path.remove(os.path.join(self.bb_vars['TMPDIR'], 'cache'), True)
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_2',
+ 'bitbake -p (no tmp/cache)')
+ # Parse with fully cached data
+ self.measure_cmd_resources(['bitbake', '-p'], 'parse_3',
+ 'bitbake -p (cached)')
+ </literallayout>This
+ example shows how three specific parsing timings are measured, with and without
+ various caches, to show how BitBake's parsing performance trends over time.</para>

+ <title>Considerations When Writing Tests</title>
+ <para>When writing good tests, there are several things to keep in mind. Since things
+ running on the Autobuilder are accessed concurrently by multiple workers, consider the
+ following:</para>
+ <formalpara>
+ <title>Running "cleanall" is not permitted</title>
+ <para>This can delete files from DL_DIR which would potentially break other builds
+ running in parallel. If this is required, DL_DIR must be set to an isolated
+ directory.</para>
+ </formalpara>
+ <formalpara>
+ <title>Running "cleansstate" is not permitted</title>
+ <para>This can delete files from SSTATE_DIR which would potentially break other builds
+ running in parallel. If this is required, SSTATE_DIR must be set to an isolated
+ directory. Alternatively, you can use the "-f" option with the
+ <filename>bitbake</filename> command to "taint" tasks by changing the sstate
+ checksums to ensure sstate cache items will not be reused.</para>
+ </formalpara>
+ <formalpara>
+ <title>Tests should not change the metadata</title>
+ <para>This is particularly true for oe-selftests since these can run in parallel and
+ changing metadata leads to changing checksums, which confuses BitBake while running
+ in parallel. If this is necessary, copy layers to a temporary location and modify
+ them. Some tests need to change metadata, such as the devtool tests. To prevent the
+ metadate from changes, set up temporary copies of that data first.</para>
+ </formalpara>

+Project Testing and Release Process
+***********************************
+
+.. _test-daily-devel:
+
+Day to Day Development
+======================
+
+This section details how the project tests changes, through automation
+on the Autobuilder or with the assistance of QA teams, through to making
+releases.
+
+The project aims to test changes against our test matrix before those
+changes are merged into the master branch. As such, changes are queued
+up in batches either in the ``master-next`` branch in the main trees, or
+in user trees such as ``ross/mut`` in ``poky-contrib`` (Ross Burton
+helps review and test patches and this is his testing tree).
+
+We have two broad categories of test builds, including "full" and
+"quick". On the Autobuilder, these can be seen as "a-quick" and
+"a-full", simply for ease of sorting in the UI. Use our Autobuilder
+console view to see where me manage most test-related items, available
+at: :yocto_ab:`/typhoon/#/console`.
+
+Builds are triggered manually when the test branches are ready. The
+builds are monitored by the SWAT team. For additional information, see
+:yocto_wiki:`/wiki/Yocto_Build_Failure_Swat_Team`.
+If successful, the changes would usually be merged to the ``master``
+branch. If not successful, someone would respond to the changes on the
+mailing list explaining that there was a failure in testing. The choice
+of quick or full would depend on the type of changes and the speed with
+which the result was required.
+
+The Autobuilder does build the ``master`` branch once daily for several
+reasons, in particular, to ensure the current ``master`` branch does
+build, but also to keep ``yocto-testresults``
+(:yocto_git:`/cgit.cgi/yocto-testresults/`),
+buildhistory
+(:yocto_git:`/cgit.cgi/poky-buildhistory/`), and
+our sstate up to date. On the weekend, there is a master-next build
+instead to ensure the test results are updated for the less frequently
+run targets.
+
+Performance builds (buildperf-\* targets in the console) are triggered
+separately every six hours and automatically push their results to the
+buildstats repository at:
+:yocto_git:`/cgit.cgi/yocto-buildstats/`.
+
+The 'quick' targets have been selected to be the ones which catch the
+most failures or give the most valuable data. We run 'fast' ptests in
+this case for example but not the ones which take a long time. The quick
+target doesn't include \*-lsb builds for all architectures, some world
+builds and doesn't trigger performance tests or ltp testing. The full
+build includes all these things and is slower but more comprehensive.
+
+Release Builds
+==============
+
+The project typically has two major releases a year with a six month
+cadence in April and October. Between these there would be a number of
+milestone releases (usually four) with the final one being stablization
+only along with point releases of our stable branches.
+
+The build and release process for these project releases is similar to
+that in `Day to Day Development <#test-daily-devel>`__, in that the
+a-full target of the Autobuilder is used but in addition the form is
+configured to generate and publish artefacts and the milestone number,
+version, release candidate number and other information is entered. The
+box to "generate an email to QA"is also checked.
+
+When the build completes, an email is sent out using the send-qa-email
+script in the ``yocto-autobuilder-helper`` repository to the list of
+people configured for that release. Release builds are placed into a
+directory in https://autobuilder.yocto.io/pub/releases on the
+Autobuilder which is included in the email. The process from here is
+more manual and control is effectively passed to release engineering.
+The next steps include:
+
+- QA teams respond to the email saying which tests they plan to run and
+ when the results will be available.
+
+- QA teams run their tests and share their results in the yocto-
+ testresults-contrib repository, along with a summary of their
+ findings.
+
+- Release engineering prepare the release as per their process.
+
+- Test results from the QA teams are included into the release in
+ separate directories and also uploaded to the yocto-testresults
+ repository alongside the other test results for the given revision.
+
+- The QA report in the final release is regenerated using resulttool to
+ include the new test results and the test summaries from the teams
+ (as headers to the generated report).
+
+- The release is checked against the release checklist and release
+ readiness criteria.
+
+- A final decision on whether to release is made by the YP TSC who have
+ final oversight on release readiness.

+*******************************************
+Understanding the Yocto Project Autobuilder
+*******************************************
+
+Execution Flow within the Autobuilder
+=====================================
+
+The "a-full" and "a-quick" targets are the usual entry points into the
+Autobuilder and it makes sense to follow the process through the system
+starting there. This is best visualised from the Autobuilder Console
+view (:yocto_ab:`/typhoon/#/console`).
+
+Each item along the top of that view represents some "target build" and
+these targets are all run in parallel. The 'full' build will trigger the
+majority of them, the "quick" build will trigger some subset of them.
+The Autobuilder effectively runs whichever configuration is defined for
+each of those targets on a seperate buildbot worker. To understand the
+configuration, you need to look at the entry on ``config.json`` file
+within the ``yocto-autobuilder-helper`` repository. The targets are
+defined in the ‘overrides' section, a quick example could be qemux86-64
+which looks like::
+
+ "qemux86-64" : {
+ "MACHINE" : "qemux86-64",
+ "TEMPLATE" : "arch-qemu",
+ "step1" : {
+ "extravars" : [
+ "IMAGE_FSTYPES_append = ' wic wic.bmap'"
+ ]
+ }
+ },
+
+And to expand that, you need the "arch-qemu" entry from
+the "templates" section, which looks like::
+
+ "arch-qemu" : {
+ "BUILDINFO" : true,
+ "BUILDHISTORY" : true,
+ "step1" : {
+ "BBTARGETS" : "core-image-sato core-image-sato-dev core-image-sato-sdk core-image-minimal core-image-minimal-dev core-image-sato:do_populate_sdk",
+ "SANITYTARGETS" : "core-image-minimal:do_testimage core-image-sato:do_testimage core-image-sato-sdk:do_testimage core-image-sato:do_testsdk"
+ },
+ "step2" : {
+ "SDKMACHINE" : "x86_64",
+ "BBTARGETS" : "core-image-sato:do_populate_sdk core-image-minimal:do_populate_sdk_ext core-image-sato:do_populate_sdk_ext",
+ "SANITYTARGETS" : "core-image-sato:do_testsdk core-image-minimal:do_testsdkext core-image-sato:do_testsdkext"
+ },
+ "step3" : {
+ "BUILDHISTORY" : false,
+ "EXTRACMDS" : ["${SCRIPTSDIR}/checkvnc; DISPLAY=:1 oe-selftest ${HELPERSTMACHTARGS} -j 15"],
+ "ADDLAYER" : ["${BUILDDIR}/../meta-selftest"]
+ }
+ },
+
+Combining these two entries you can see that "qemux86-64" is a three step build where the
+``bitbake BBTARGETS`` would be run, then ``bitbake SANITYTARGETS`` for each step; all for
+``MACHINE="qemx86-64"`` but with differing SDKMACHINE settings. In step
+1 an extra variable is added to the ``auto.conf`` file to enable wic
+image generation.
+
+While not every detail of this is covered here, you can see how the
+template mechanism allows quite complex configurations to be built up
+yet allows duplication and repetition to be kept to a minimum.
+
+The different build targets are designed to allow for parallelisation,
+so different machines are usually built in parallel, operations using
+the same machine and metadata are built sequentially, with the aim of
+trying to optimise build efficiency as much as possible.
+
+The ``config.json`` file is processed by the scripts in the Helper
+repository in the ``scripts`` directory. The following section details
+how this works.
+
+.. _test-autobuilder-target-exec-overview:
+
+Autobuilder Target Execution Overview
+=====================================
+
+For each given target in a build, the Autobuilder executes several
+steps. These are configured in ``yocto-autobuilder2/builders.py`` and
+roughly consist of:
+
+#. *Run clobberdir*.
+
+ This cleans out any previous build. Old builds are left around to
+ allow easier debugging of failed builds. For additional information,
+ see :ref:`test-manual/test-manual-understand-autobuilder:clobberdir`.
+
+#. *Obtain yocto-autobuilder-helper*
+
+ This step clones the ``yocto-autobuilder-helper`` git repository.
+ This is necessary to prevent the requirement to maintain all the
+ release or project-specific code within Buildbot. The branch chosen
+ matches the release being built so we can support older releases and
+ still make changes in newer ones.
+
+#. *Write layerinfo.json*
+
+ This transfers data in the Buildbot UI when the build was configured
+ to the Helper.
+
+#. *Call scripts/shared-repo-unpack*
+
+ This is a call into the Helper scripts to set up a checkout of all
+ the pieces this build might need. It might clone the BitBake
+ repository and the OpenEmbedded-Core repository. It may clone the
+ Poky repository, as well as additional layers. It will use the data
+ from the ``layerinfo.json`` file to help understand the
+ configuration. It will also use a local cache of repositories to
+ speed up the clone checkouts. For additional information, see
+ :ref:`test-manual/test-manual-understand-autobuilder:Autobuilder Clone Cache`.
+
+ This step has two possible modes of operation. If the build is part
+ of a parent build, its possible that all the repositories needed may
+ already be available, ready in a pre-prepared directory. An "a-quick"
+ or "a-full" build would prepare this before starting the other
+ sub-target builds. This is done for two reasons:
+
+ - the upstream may change during a build, for example, from a forced
+ push and this ensures we have matching content for the whole build
+
+ - if 15 Workers all tried to pull the same data from the same repos,
+ we can hit resource limits on upstream servers as they can think
+ they are under some kind of network attack
+
+ This pre-prepared directory is shared among the Workers over NFS. If
+ the build is an individual build and there is no "shared" directory
+ available, it would clone from the cache and the upstreams as
+ necessary. This is considered the fallback mode.
+
+#. *Call scripts/run-config*
+
+ This is another call into the Helper scripts where its expected that
+ the main functionality of this target will be executed.
+
+.. _test-autobuilder-tech:
+
+Autobuilder Technology
+======================
+
+The Autobuilder has Yocto Project-specific functionality to allow builds
+to operate with increased efficiency and speed.
+
+.. _test-clobberdir:
+
+clobberdir
+----------
+
+When deleting files, the Autobuilder uses ``clobberdir``, which is a
+special script that moves files to a special location, rather than
+deleting them. Files in this location are deleted by an ``rm`` command,
+which is run under ``ionice -c 3``. For example, the deletion only
+happens when there is idle IO capacity on the Worker. The Autobuilder
+Worker Janitor runs this deletion. See :ref:`test-manual/test-manual-understand-autobuilder:Autobuilder Worker Janitor`.
+
+.. _test-autobuilder-clone-cache:
+
+Autobuilder Clone Cache
+-----------------------
+
+Cloning repositories from scratch each time they are required was slow
+on the Autobuilder. We therefore have a stash of commonly used
+repositories pre-cloned on the Workers. Data is fetched from these
+during clones first, then "topped up" with later revisions from any
+upstream when necesary. The cache is maintained by the Autobuilder
+Worker Janitor. See :ref:`test-manual/test-manual-understand-autobuilder:Autobuilder Worker Janitor`.
+
+.. _test-autobuilder-worker-janitor:
+
+Autobuilder Worker Janitor
+--------------------------
+
+This is a process running on each Worker that performs two basic
+operations, including background file deletion at IO idle (see :ref:`test-manual/test-manual-understand-autobuilder:Autobuilder Target Execution Overview`: Run clobberdir) and
+maintainenance of a cache of cloned repositories to improve the speed
+the system can checkout repositories.
+
+.. _test-shared-dl-dir:
+
+Shared DL_DIR
+-------------
+
+The Workers are all connected over NFS which allows DL_DIR to be shared
+between them. This reduces network accesses from the system and allows
+the build to be sped up. Usage of the directory within the build system
+is designed to be able to be shared over NFS.
+
+.. _test-shared-sstate-cache:
+
+Shared SSTATE_DIR
+-----------------
+
+The Workers are all connected over NFS which allows the ``sstate``
+directory to be shared between them. This means once a Worker has built
+an artifact, all the others can benefit from it. Usage of the directory
+within the directory is designed for sharing over NFS.
+
+.. _test-resulttool:
+
+Resulttool
+----------
+
+All of the different tests run as part of the build generate output into
+``testresults.json`` files. This allows us to determine which tests ran
+in a given build and their status. Additional information, such as
+failure logs or the time taken to run the tests, may also be included.
+
+Resulttool is part of OpenEmbedded-Core and is used to manipulate these
+json results files. It has the ability to merge files together, display
+reports of the test results and compare different result files.
+
+For details, see :yocto_wiki:`/wiki/Resulttool`.
+
+.. _test-run-config-tgt-execution:
+
+run-config Target Execution
+===========================
+
+The ``scripts/run-config`` execution is where most of the work within
+the Autobuilder happens. It runs through a number of steps; the first
+are general setup steps that are run once and include:
+
+#. Set up any ``buildtools-tarball`` if configured.
+
+#. Call "buildhistory-init" if buildhistory is configured.
+
+For each step that is configured in ``config.json``, it will perform the
+following:
+
+#. Add any layers that are specified using the
+ ``bitbake-layers add-layer`` command (logging as stepXa)
+
+#. Call the ``scripts/setup-config`` script to generate the necessary
+ ``auto.conf`` configuration file for the build
+
+#. Run the ``bitbake BBTARGETS`` command (logging as stepXb)
+
+#. Run the ``bitbake SANITYTARGETS`` command (logging as stepXc)
+
+#. Run the ``EXTRACMDS`` command, which are run within the BitBake build
+ environment (logging as stepXd)
+
+#. Run the ``EXTRAPLAINCMDS`` command(s), which are run outside the
+ BitBake build environment (logging as stepXd)
+
+#. Remove any layers added in step
+ 1 using the ``bitbake-layers remove-layer`` command (logging as stepXa)
+
+Once the execution steps above complete, ``run-config`` executes a set
+of post-build steps, including:
+
+#. Call ``scripts/publish-artifacts`` to collect any output which is to
+ be saved from the build.
+
+#. Call ``scripts/collect-results`` to collect any test results to be
+ saved from the build.
+
+#. Call ``scripts/upload-error-reports`` to send any error reports
+ generated to the remote server.
+
+#. Cleanup the build directory using
+ :ref:`test-manual/test-manual-understand-autobuilder:clobberdir` if the build was successful,
+ else rename it to "build-renamed" for potential future debugging.
+
+.. _test-deploying-yp-autobuilder:
+
+Deploying Yocto Autobuilder
+===========================
+
+The most up to date information about how to setup and deploy your own
+Autbuilder can be found in README.md in the ``yocto-autobuilder2``
+repository.
+
+We hope that people can use the ``yocto-autobuilder2`` code directly but
+it is inevitable that users will end up needing to heavily customise the
+``yocto-autobuilder-helper`` repository, particularly the
+``config.json`` file as they will want to define their own test matrix.
+
+The Autobuilder supports wo customization options:
+
+- variable substitution
+
+- overlaying configuration files
+
+The standard ``config.json`` minimally attempts to allow substitution of
+the paths. The Helper script repository includes a
+``local-example.json`` file to show how you could override these from a
+separate configuration file. Pass the following into the environment of
+the Autobuilder::
+
+ $ ABHELPER_JSON="config.json local-example.json"
+
+As another example, you could also pass the following into the
+environment::
+
+ $ ABHELPER_JSON="config.json /some/location/local.json"
+
+One issue users often run into is validation of the ``config.json`` files. A
+tip for minimizing issues from invalid json files is to use a Git
+``pre-commit-hook.sh`` script to verify the JSON file before committing
+it. Create a symbolic link as follows::
+
+ $ ln -s ../../scripts/pre-commit-hook.sh .git/hooks/pre-commit

+ </literallayout>Combining
+ these two entries you can see that "qemux86-64" is a three step build where the
+ <filename>bitbake BBTARGETS</filename> would be run, then <filename>bitbake
+ SANITYTARGETS</filename> for each step; all for
+ <filename>MACHINE="qemx86-64"</filename> but with differing SDKMACHINE settings. In
+ step 1 an extra variable is added to the <filename>auto.conf</filename> file to enable
+ wic image generation.</para>
+ <para>While not every detail of this is covered here, you can see how the templating
+ mechanism allows quite complex configurations to be built up yet allows duplication and
+ repetition to be kept to a minimum.</para>
+ <para>The different build targets are designed to allow for parallelisation, so different
+ machines are usually built in parallel, operations using the same machine and metadata
+ are built sequentially, with the aim of trying to optimise build efficiency as much as
+ possible.</para>
+ <para>The <filename>config.json</filename> file is processed by the scripts in the Helper
+ repository in the <filename>scripts</filename> directory. The following section details
+ how this works.</para>
+ </section>
+
+ <section id='test-autobuilder-target-exec-overview'>
+ <title>Autobuilder Target Execution Overview</title>
+
+ <para>For each given target in a build, the Autobuilder executes several steps. These are
+ configured in <filename>yocto-autobuilder2/builders.py</filename> and roughly consist
+ of: <orderedlist>
+ <listitem id='test-list-tgt-exec-clobberdir'>
+ <para><emphasis>Run <filename>clobberdir</filename></emphasis></para>
+ <para>This cleans out any previous build. Old builds are left around to allow
+ easier debugging of failed builds. For additional information, see <link
+ linkend="test-clobberdir"><filename>clobberdir</filename></link>.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis>Obtain yocto-autobuilder-helper</emphasis></para>
+ <para>This step clones the <filename>yocto-autobuilder-helper</filename> git
+ repository. This is necessary to prevent the requirement to maintain all the
+ release or project-specific code within Buildbot. The branch chosen matches
+ the release being built so we can support older releases and still make
+ changes in newer ones.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis>Write layerinfo.json</emphasis></para>
+ <para>This transfers data in the Buildbot UI when the build was configured to
+ the Helper.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis>Call scripts/shared-repo-unpack</emphasis></para>
+ <para>This is a call into the Helper scripts to set up a checkout of all the
+ pieces this build might need. It might clone the BitBake repository and the
+ OpenEmbedded-Core repository. It may clone the Poky repository, as well as
+ additional layers. It will use the data from the
+ <filename>layerinfo.json</filename> file to help understand the
+ configuration. It will also use a local cache of repositories to speed up
+ the clone checkouts. For additional information, see <link
+ linkend="test-autobuilder-clone-cache">Autobuilder Clone
+ Cache</link>.</para>
+ <para>This step has two possible modes of operation. If the build is part of a
+ parent build, its possible that all the repositories needed may already be
+ available, ready in a pre-prepared directory. An "a-quick" or "a-full" build
+ would prepare this before starting the other sub-target builds. This is done
+ for two reasons:<itemizedlist>
+ <listitem>
+ <para>the upstream may change during a build, for example, from a
+ forced push and this ensures we have matching content for the
+ whole build</para>
+ </listitem>
+ <listitem>
+ <para>if 15 Workers all tried to pull the same data from the same
+ repos, we can hit resource limits on upstream servers as they
+ can think they are under some kind of network attack</para>
+ </listitem>
+ </itemizedlist>This pre-prepared directory is shared among the Workers over
+ NFS. If the build is an individual build and there is no "shared" directory
+ available, it would clone from the cache and the upstreams as necessary.
+ This is considered the fallback mode.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis>Call scripts/run-config</emphasis></para>
+ <para>This is another call into the Helper scripts where its expected that the
+ main functionality of this target will be executed.</para>
+ </listitem>
+ </orderedlist></para>
+ </section>
+ <section id='test-autobuilder-tech'>
+ <title>Autobuilder Technology</title>
+ <para>The Autobuilder has Yocto Project-specific functionality to allow builds to operate
+ with increased efficiency and speed.</para>
+ <section id='test-clobberdir'>
+ <title>clobberdir</title>
+ <para>When deleting files, the Autobuilder uses <filename>clobberdir</filename>, which
+ is a special script that moves files to a special location, rather than deleting
+ them. Files in this location are deleted by an <filename>rm</filename> command,
+ which is run under <filename>ionice -c 3</filename>. For example, the deletion only
+ happens when there is idle IO capacity on the Worker. The Autobuilder Worker Janitor
+ runs this deletion. See <link linkend="test-autobuilder-worker-janitor">Autobuilder
+ Worker Janitor</link>.</para>
+ </section>
+ <section id='test-autobuilder-clone-cache'>
+ <title>Autobuilder Clone Cache</title>
+ <para>Cloning repositories from scratch each time they are required was slow on the
+ Autobuilder. We therefore have a stash of commonly used repositories pre-cloned on
+ the Workers. Data is fetched from these during clones first, then "topped up" with
+ later revisions from any upstream when necesary. The cache is maintained by the
+ Autobuilder Worker Janitor. See <link linkend="test-autobuilder-worker-janitor"
+ >Autobuilder Worker Janitor</link>.</para>
+ </section>
+ <section id='test-autobuilder-worker-janitor'>
+ <title>Autobuilder Worker Janitor</title>
+ <para>This is a process running on each Worker that performs two basic operations,
+ including background file deletion at IO idle (see <link
+ linkend="test-list-tgt-exec-clobberdir">Target Execution: clobberdir</link>) and
+ maintainenance of a cache of cloned repositories to improve the speed the system can
+ checkout repositories.</para>
+ </section>
+ <section id='test-shared-dl-dir'>
+ <title>Shared DL_DIR</title>
+ <para>The Workers are all connected over NFS which allows DL_DIR to be shared between
+ them. This reduces network accesses from the system and allows the build to be sped
+ up. Usage of the directory within the build system is designed to be able to be
+ shared over NFS.</para>
+ </section>
+ <section id='test-shared-sstate-cache'>
+ <title>Shared SSTATE_DIR</title>
+ <para>The Workers are all connected over NFS which allows the
+ <filename>sstate</filename> directory to be shared between them. This means once
+ a Worker has built an artefact, all the others can benefit from it. Usage of the
+ directory within the directory is designed for sharing over NFS.</para>
+ </section>
+ <section id='test-resulttool'>
+ <title>Resulttool</title>
+ <para>All of the different tests run as part of the build generate output into
+ <filename>testresults.json</filename> files. This allows us to determine which
+ tests ran in a given build and their status. Additional information, such as failure
+ logs or the time taken to run the tests, may also be included.</para>
+ <para>Resulttool is part of OpenEmbedded-Core and is used to manipulate these json
+ results files. It has the ability to merge files together, display reports of the
+ test results and compare different result files.</para>
+ <para>For details, see <link linkend=""
+ >https://wiki.yoctoproject.org/wiki/Resulttool</link>.</para>
+ </section>
+ </section>
+ <section id='test-run-config-tgt-execution'>
+ <title>run-config Target Execution</title>
+ <para>The <filename>scripts/run-config</filename> execution is where most of the work within
+ the Autobuilder happens. It runs through a number of steps; the first are general setup
+ steps that are run once and include:<orderedlist>
+ <listitem>
+ <para>Set up any <filename>buildtools-tarball</filename> if configured.</para>
+ </listitem>

+ <title>Deploying Yocto Autobuilder</title>
+ <para>The most up to date information about how to setup and deploy your own Autbuilder can
+ be found in README.md in the <filename>yocto-autobuilder2</filename> repository.</para>
+ <para>We hope that people can use the <filename>yocto-autobuilder2</filename> code directly
+ but it is inevitable that users will end up needing to heavily customise the
+ <filename>yocto-autobuilder-helper</filename> repository, particularly the
+ <filename>config.json</filename> file as they will want to define their own test
+ matrix.</para>
+ <para>The Autobuilder supports wo customization options: <itemizedlist>
+ <listitem>
+ <para>variable substitution</para>
+ </listitem>
+ <listitem>
+ <para>overlaying configuration files</para>
+ </listitem>
+ </itemizedlist>The standard <filename>config.json</filename> minimally attempts to allow
+ substitution of the paths. The Helper script repository includes a
+ <filename>local-example.json</filename> file to show how you could override these
+ from a separate configuration file. Pass the following into the environment of the
+ Autobuilder:<literallayout class="monospaced">
+ $ ABHELPER_JSON="config.json local-example.json"
+ </literallayout>As
+ another example, you could also pass the following into the
+ environment:<literallayout class="monospaced">
+ $ ABHELPER_JSON="config.json <replaceable>/some/location/</replaceable>local.json"
+ </literallayout>One
+ issue users often run into is validation of the <filename>config.json</filename> files.
+ A tip for minimizing issues from invalid json files is to use a Git
+ <filename>pre-commit-hook.sh</filename> script to verify the JSON file before
+ committing it. Create a symbolic link as
+ follows:<literallayout class="monospaced">
+ $ ln -s ../../scripts/pre-commit-hook.sh .git/hooks/pre-commit
+ </literallayout></para>
