Current problem

Currently the test_messages_documentation.py file is in the doc folder.

I usually like to run the full test suite via pytest tests -n 8 before submitting a PR (because it's faster than waiting for CI).
However, this doesn't include test_messages_documentation.py since it's in a diff folder. Could we move it over to the tests folder for convenience?

Desired solution

As above
