include tests in sdist

References

• fixes Please package testsuite to the distribution tarball #453

Changes

• includes the tests in the .tar.gz
  • this will allow downstream package maintainers to confidently test the code when re-packaging
• does not
  • include the tests in the whl
  • create an importable module called tests, which happens all over, because there is no tests/__init__.py

@bollwyvl what's the relationship between this and #393 ? Does this re-implement part of it? If so, I think we should merge this one quickly, and potentially close the other one since I think moving the tests to another folder warrants team discussion.

[bollwyvl]

This approach does exactly #453 and no more, while #393 would also include the tests in whls.

So this is probably preferable for most purposes:

• downstreams get the tests (and then may choose to further distribute them, or not)
• "nornal" pip usage keeps the same download profile, as the whl continues to not include the tests

woot - then let's 🚢 it :-)
