python.testing.cwd ignored when discovering or running tests using unittest

The issues is similar to https://github.com/microsoft/vscode-python/issues/8678 , but is about unittest, not pytest

Environment data

• VS Code version: 1.44.0
• Extension version: 2020.4.74986
• OS and version: Windows 10 Pro 1903
• Python version: python 3.7.4 x64
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A
• Relevant/affected Python packages and their versions: N/A
• Relevant/affected Python-related VS Code extensions and their versions: N/A
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): True
• Value of the python.languageServer setting: Microsoft

Expected behaviour

Set python.testing.cwd to correct directory in Workspace settings. Try discovering tests. The test discovery uses the provided cwd.

Actual behaviour

The test discovery ignores the provided cwd.

Output for Python in the Output panel:

Here is what I see during test discovery: (My python.testing.cwd is set to “sdk/python” or “<workspace_root>/sdk/python”).

> .../python ...\.vscode\extensions\ms-python.python-2020.4.74986\pythonFiles\pyvsc-run-isolated.py -c "
import unittest
loader = unittest.TestLoader()
suites = loader.discover(".", pattern="*test*.py")
print("start") #Don't remove this line
for suite in suites._tests:
    for cls in suite._tests:
        try:
            for m in cls._tests:
                print(m.id())
        except:
            pass"
cwd: <workspace_root>

See how the bottom line prints a different value of cwd.

P.S. I’m seeing the above log twice every time I try discovering the tests…

Closing this, since the original issue with unittest should be addressed in the latest release. @Ark-kun Please let me know if this is not addressed by 2020.4.76186
