Integration tests refactoring

[carlwr]

I was considering contributing some refactoring of the integration tests; something like speeding them up (there's some low hanging fruit there), adding some structure, dropping the unittest imports in favour of pytest functionality and incorporating some other testing best practices. I also see a possibility of reducing the test code LOC (without testing less).

Would such a PR be welcome?

If so, any other guidelines/preferences around the tests that could be useful for me to know in advance?

Would be great to refactor current tests, since they are not well written. LOC code optimisations are always welcome. There are few resources might be usefull:

• Typer testing
• OpenAI tests

We also have a unit test module where we can add more tests with mocked responses (as OpenAI tests).
