Vscode PyTest - TypeError: Cannot read property '$' of undefined #243

mr-narender · 2019-08-16T07:15:34Z

Describe the bug
while trying to configure and run a PyTest via vscodium, I struck across the following error.

TypeError: Cannot read property '$' of undefined

While it seems the test case ran nicely, however, the final output has a specific error message as shown above.

Please confirm that this problem is VSCodium-specific

This bug does happen if I use Microsoft's Visual Studio Code.

Please confirm that the issue/resolution isn't already documented

I checked the Docs page and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

Create a test suite in python (I choose pytest)
Run Python: Discover Tests and choose test directory appropriately and then run them.
Scroll down to output message at the bottom and notice the error
See error message which says TypeError: Cannot read property '$' of undefined

Expected behavior
Notice the error message which says TypeError: Cannot read property '$' of undefined

Just happened to me as well. It was working fine previously, I then did a git rebase which included changing dev dependencies in Pipfile (pipenv). After the pipenv install --dev, I restarted vscode and this error starting showing up when running my tests (pytest).

Same issue here. It seems it is the python extension:

cornel-masson · 2019-08-19T08:37:43Z

@asherf: Thanks, downgrading pytest to 5.0.1 does the trick. I guess we can close this one?

domoritz · 2019-08-19T08:42:40Z

Shouldn't this plugin work with the latest version of pytest?

stripedpajamas · 2019-08-19T13:34:10Z

The plug-in should work with the latest version of pytest, and that can be solved in the plug-in repo.

Closing this as there is no issue with VSCodium here.
