CI exercise fails #37
Description
CI exercise fails because pytest cannot find any tests.
This is because the default github workflow runs pytest without any arguments. By default, pytest searches for files that start with test_. It won't find any because we have only asked the participants to create a file called example.py.
Either instruct the participants to create just a file test_example.py, or ask the participants to create two files (example.py and test_example.py).
The latter option requires the participants to import the add function into test_example.py, which can give some issues, so easiest it would be to just rename the original file.
