Include new library files in coverage measurement

[alexmojaki]

Currently GHA has coverage run --include=executing/executing.py <run tests> which doesn't measure coverage in the recently added files in the executing folder. The original motivation was lines in __init__.py that would never be covered, but that should be handled by a # pragma: no cover comment or something.

Can we also add the tests/ folder to the coverage analysis? It should be assumed that the tests are always executed to 100% but I experienced several times that this is not always the case.

The error reporting for example had some issues in #51, which was not noticeable because it was not covered by the tests.

Some way to generate the coverage html reports locally would also be helpful.

You need a .coveragerc file, specially with omit section:

If you want, but let's consider that a higher goal. It's not something I've done before.

For the main library files, probably not. If we include the tests folder, that'd probably be a good way to exclude samples.
