1279237 - Can't run desktop_unittest.py with a custom --base-work-dir

Status: NEW

(Release Engineering :: Applications: MozharnessCore, defect)

Description

[Andrew Halberstadt [:ahal]]

If you try to change the base_work_dir via commandline, desktop_unittest.py will fail. This is because the config files completely ignore it by hardcoding os.getcwd():
https://dxr.mozilla.org/mozilla-central/source/testing/mozharness/configs/unittests/linux_unittest.py#5

So basically you need to pass in --base-work-dir, then cd to that directory as well. But if you cd there, then --base-work-dir becomes redundant as os.getcwd() is the default for it anyway.

The config values that use that ABS_WORK_DIR variable should get set at runtime (after base_work_dir is calculated). This is another example of immutable configs being a pita.

This isn't blocking me as I can work around it with the 'cd' fix. But using os.getcwd() in those config files just seems wrong.
