From 623b3a579765f8e05723bd1eff6f8c7e56d33922 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 15 Sep 2017 10:06:11 +0200 Subject: efi_selftest: provide an EFI selftest application A testing framework for the EFI API is provided. It can be executed with the 'bootefi selftest' command. It is coded in a way that at a later stage we may turn it into a standalone EFI application. The current build system does not allow this yet. All tests use a driver model and are run in three phases: setup, execute, teardown. A test may be setup and executed at boottime, it may be setup at boottime and executed at runtime, or it may be setup and executed at runtime. After executing all tests the system is reset.
