Tests not working properly for chapter 6

[KheireddineOtm]

Dear all,
I have been working through the exercises in Chapter 6 and encountered an issue with the classroom.yml file. It appears that the test workflow is not properly installing the Python environment. Specifically, the virtual environment setup and package installations are not being handled correctly, leading to failures when attempting to run tests.

Could you kindly review the classroom.yml file and ensure that the Python environment is being configured correctly?

Thanks.

Regards
