python.testing.cwd does not work properly

Update setting description saying it only works with absolute paths. Folks often try relative paths which do not work for them Error: spawn <python interpreter> ENOENT on test discovery when "python.testing.cwd" is set #15739 (comment).
For some reason we need to reload window everytime for changes in the setting to take effect.
It seems the setting doesn't work when using forward slashes in windows:
Have the following test ./Test/test2.py where . is workspace folder

import unittest   # The test framework

class Test_TestIncrementDecrement1(unittest.TestCase):
    def test_increment(self):
        f = open("./demofile.txt", "r")
        print(f.read())
        self.assertEqual(2, 4)


if __name__ == '__main__':
    unittest.main()

And ./demofile.txt carrying some random content.
Set python.testing.cwd to ./Test. Run the file, it doesn't work. Setting python.testing.cwd to .\\Test works.

The below setting is working for me with python unittest

{
    "python.testing.cwd": "path\to\yourworkingdir",
    "python.testing.unittestArgs": [
        "-v",
        "-s",
        ".",
        "-p",
        "test_*.py"
    ],
    "python.testing.unittestEnabled": true,
}

Remember you need to restart your VSCode application after modify your settings.json file.

This issue is about having . in python.testing.cwd. Does that work for you?

I don't think having . in python.testing.cwd or not is difference.
"python.testing.cwd": ".\\path\to\yourworkingdir" still working for me.

Kartik Raj (@karrtikr) what's way you running for test.

If using launch.json file and run directly your file, you need to set working directory manually with cwd property

"configurations": [
	{
		"name": "Python: Current File",
		"type": "python",
		"request": "launch",
		"program": "${file}",
		"console": "integratedTerminal",
		"cwd": "${fileDirname}"
	}
]

You also able to using TEST EXPLORER of VSCode for testing with setting in my previous comment.
But you will be got a problems with TEST EXPLORER of VSCode: run a test case or test class is working normally but debugging will throws an exception Unhandled exception in thread started by.

I am running the tests directly using play button, not debugging it.
And that's not how you set debugging which is why it's throwing an error, please see #11587. If that doesn't work I recommend to open up a new issue.

This launchfile doesnt work for me anymore... Do you have the same problem?

everything works in this issue except: "need to reload window everytime for changes in the setting to take effect". Will create another issue about this specifically but all other aspects of this issue are resolved.
