Verification steps:

• Install the Insiders build of the Python extension using Python: Switch to Insiders weekly command.
• Make sure you have "python.experiments.optInto": ["All"], in your user settings. If you did not have it, add it and reload.
• Create a new folder containing a python file named pytest_test.py. (name is important)
• Add the following content:

def test_passing():
    assert 42 == 42
def test_failure():
    assert 42 == -13

• Select a Python interpreter and create new terminal.
• Click the test explorer icon on the explorer tab to the left and click Configure Python tests:
  
• Select pytest in the dropdown and select directory containing the tests:
  
• If pytest is not installed, install it using pip in the dropdown displayed. Click the refresh icon to rediscover tests in that case.
  
• You can also run the following command to install pytest: python -m pip install pytest if no such dropdown is displayed. Do leave a comment in this case.
• Run all tests using the icon above and verify the tests are run successfully:
