Unfortunately, this test had not been added to meson.build, so we did not notice a regression: Looking for 'Kernel panic - not syncing: VFS:' as the indication for the final boot state of the kernel was a bad idea since 'Kernel panic - not syncing' is the default failure message of the LinuxKernelTest class, and since we're now reading the console input byte by byte instead of linewise (see commitcdad03b74f), the failure now triggers before we fully read the success string. Let's fix this by simply looking for the previous line in the console output instead. Also, replace the call to cancel() - this was only available in the Avocado framework. In the functional framework, we must use skipTest() instead. While we're at it, also fix the TODO here by looking for the exact error and only skip the test if the plugins are not available. Fixes:3abc545e66("tests/functional: Convert the tcg_plugins test") Fixes:cdad03b74f("tests/functional: rewrite console handling to be bytewise") Message-ID: <20250123083625.1498495-1-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
