Testing - Test View for Python unittest #17039
Description
Refs: #15750
- macOS Don Jayamanne (@DonJayamanne)
- linux Greg Van Liew (@gregvanl)
- windows Alex Ross (@alexr00)
Complexity: 3
Requirements
- Install python extension from here: https://pvsc.blob.core.windows.net/extension-builds/ms-python-insiders.vsix
- Make sure you have
"python.experiments.optInto": ["All"],in your user settings. If you did not have it, add it and reload.
Testing
- Open an empty folder in VS Code.
- Add following
unittestcode (name your filemy_tests.py). Do not name itunittest.pythat will override theunittestlibrary:
import unittest
class PassingTests(unittest.TestCase):
def test_passing(self):
self.assertEqual(42, 42)
def test_passing_still(self):
self.assertEqual("silly walk", "silly walk")
class FailingTests(unittest.TestCase):
def test_failure(self):
self.assertEqual(42, -13)
def test_failure_still(self):
self.assertEqual("I'm right!", "no, I am!")- Select any python version.
- You can either configure tests using
Python: configure tests...command from the command pallet, or go the test view and configure by using the welcome view, or you can run tests to get a prompt to configure. - Select
unittestframework. - You should see the tests in the test view. Run the tests.
- Add your own test methods, or add another test file, the test UI should update accordingly.

I followed both of the Requirements steps, but I wasn't able to get this working. Am I missing something?

Alex Ross (@alexr00) It looks like the test file detection is really fragile. For example if you specify searching for the pattern "*test.py", it will detect a file called "utest.py" but not with more than one character (for example "untest.py").
I was able to get detection to work most reliably with just "test.py".
I'll enter an issue.

Tried your suggestion Greg Van Liew (@gregvanl) of naming the file utest.py, but it still doesn't work.

I see that the file name is
unittest.py, in python the file names are module names. So, if you create a file by the nameunittest.pythen importunittestin it then it overrides the underlyingunittestlibrary. Please name it something else.karthiknadig commentedon Aug 24, 2021
Alex Ross (@alexr00) When the config settings are generated see if they look like this. If not, try and add this to
settings.jsonfor the project and see if that helps:DonJayamanne commentedon Aug 24, 2021

I had tested with utest.py yesterday without success. Today I deleted everything in my folder, reloaded, and started over. Success.
