Unit test not available for Python

Unit tests not working for Python!!!

Unit tests are not currently supported for this language.

Earlier I was successfully able to set up python project using unit test cases. However when I tried setting up new projects, it showed the above prompt for unit tests.
Can someone let me know how can I access unit tests? Or is it a Replit’s bug.?

This is a known bug but there is a workaround:

The .replit file is a hidden file: you need to show hidden files to see it.

The main topic for this issue is here:
