[PATCH 1/2] kunit: tool: test: Rename test_data_path() to _test_data_path()

[Thomas Weißschuh]

Running the KUnit testsuite through pytest fails, as the function
test_data_path() is recognized as a test function. Its execution fails
as pytest tries to resolve the 'path' argument as a fixture which does
not exist.

Rename the function, so the helper function is not incorrectly
recognized as a test function.

Thanks -- I'd never tried pytest, but it's working with this series.

Although, it's worth noting that we add another call to
test_data_path() in "kunit: tool: Add test for nested test result
reporting", which conflicts here.

[David Gow]

From: Thomas Weißschuh <thomas.w...@linutronix.de>

If no kunitconfig_paths are passed to LinuxSourceTree() it falls back to
DEFAULT_KUNITCONFIG_PATH. This resolution only works when the current
working directory is the root of the source tree. This works by chance
when running the full testsuite through the default unittest runner, as
some tests will change the current working directory as a side-effect of
'kunit.main()'. When running a single testcase or using pytest, which
resets the working directory for each test, this assumption breaks.

Explicitly specify an empty kunitconfig for the affected tests.

If no kunitconfig_paths are passed to LinuxSourceTree() it falls back to
DEFAULT_KUNITCONFIG_PATH. This resolution only works when the current
working directory is the root of the source tree. This works by chance
when running the full testsuite through the default unittest runner, as
some tests will change the current working directory as a side-effect of
'kunit.main()'. When running a single testcase or using pytest, which
resets the working directory for each test, this assumption breaks.

Explicitly specify an empty kunitconfig for the affected tests.
