Pytest discovery is triggered even though unittest is the enabled framework

[luabud]

Type: Bug

Behaviour

When trying to set up test discovery with unittest, I can only get pytest to trigger discovery to trigger. Even though I have the following settings in my workspace:

    "python.testing.unittestArgs": [
        "-v",
        "-s",
        "./tests",
        "-p",
        "test_*.py"
    ],
    "python.testing.pytestEnabled": false,
    "python.testing.unittestEnabled": true

Steps to reproduce:

1. Create a new empty folder
2. Add a file called e.g. test_1.py with the following content:

import unittest


class TestStringMethods(unittest.TestCase):
    def test_upper(self):
        self.assertEqual("hello".upper(), "HELLO")

    def test_isupper(self):
        self.assertTrue("HELLO".isupper())
        self.assertFalse("Hello".isupper())

    def test_split(self):
        s = "hello world"
        self.assertEqual(s.split(), ["hello", "world"])
        # check that s.split fails when the separator is not a string
        with self.assertRaises(TypeError):
            s.split(2)

3. Click on the test explorer, select configure tests, select "unittest" and then "." and then "test_*.py"
4. See that it will fail pytest discovery
