Subject: [PATCH v2 4/4] minor: kunit: tool: fix unit test so it can run from
non-root dir
Also take this time to rename get_absolute_path() to test_data_path().
1. the name is currently a lie. It gives relative paths, e.g. if I run
from the same dir as the test file, it gives './test_data/<file>'
See https://docs.python.org/3/reference/import.html#__file__, which
doesn't stipulate that implementations provide absolute paths.
2. it's only used for generating paths to tools/testing/kunit/test_data/
So we can tersen things by making it less general.
Cache the absolute path to the test data files per suggestion from [1].
Using relative paths, the tests break because of this code in kunit.py
if get_kernel_root_path():
os.chdir(get_kernel_root_path())
[1] https://lore.kernel.org/linux-kselftest/CABVgOSnH0gz7z5JhRCGyG1wg0zDDBTLoSUCoB-gWMeXLgVTo2w@mail.gmail.com/
Fixes: 5578d008d9e0 ("kunit: tool: fix running kunit_tool from outside kernel tree")
