From 12f1e7908af97d901cc640da17e8ceea890c37a4 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 23 Nov 2019 18:15:23 +0100 Subject: dm: test: usb: rework keyboard test Allow the unit test to pass full 8 byte scan code sequences to the USB keyboard emulation driver and to parse multi-byte escape sequences. The following features are not yet tested: * LED status * caps-lock * num-lock * numerical pad keys The following features are not yet implemented by the USB keyboard driver and therefore not tested: * modifiers for non-alpha-numeric keys, e.g. and * some special keys, e.g. * some modifiers, e.g. and * alternative keyboard layouts Signed-off-by: Heinrich Schuchardt --- test/dm/usb.c | 284 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 276 insertions(+), 8 deletions(-) (limited to 'test') diff --git a/test/dm/usb.c b/test/dm/usb.c index ef454b0ae5..e396c2a0ea 100644 --- a/test/dm/usb.c +++ b/test/dm/usb.c @@ -15,6 +15,12 @@ #include #include +struct keyboard_test_data { + const char modifiers; + const char scancode; + const char result[6]; +}; + /* Test that sandbox USB works correctly */ static int dm_test_usb_base(struct unit_test_state *uts) { @@ -115,9 +121,263 @@ static int dm_test_usb_stop(struct unit_test_state *uts) } DM_TEST(dm_test_usb_stop, DM_TESTF_SCAN_PDATA | DM_TESTF_SCAN_FDT); +/** + * dm_test_usb_keyb() - test USB keyboard driver + * + * This test copies USB keyboard scan codes into the key buffer of the USB + * keyboard emulation driver.
