Mention `stress test` in `Tests overview`

[brunoerg]

In Tests overview, it would be great to short mention we have stress test in Core? It's into the functional test (to not rewrite same code) but we can consider it a different category of test.

Hello Bruno, thanks for the feedback.

I don't think I quite see how this test is different from many of the other feature_*.py tests? We have e.g. abortnode, dbcrash, shutdown etc. which all might be considered similar, perhaps you could explain a little further?

I think that personally if I heard that we had a "stress test" I would take it to mean that we have a test which exercised many of the potential DoS vectors to try and stress the CPU/RAM/Disk and check that the node doesn't fall over (although I fully take the point that the author of that PR named the commit " test: add stress tests for initialization ") 😄

Hey, sorry for the late reply!

I think you're right, this specific test is not sooo different compared to other ones we have in feature_*.py, just thought interesting to short mention it because there were some new contributors I talked about it that didn't know we could have into our functional tests this kind of tests (e.g. stressing initialization by disturbing files, etc.).

Hmmm, I agree with you actually!

Do you think something like this commit would cover it adequately enough? (and, if you'd prefer to submit the PR yourself, then please feel free!)

[brunoerg]

Yes, that commit sounds good.
