coverage reporting

[Autoplectic]

attest should have some way to report test coverage, probably using coverage.py. this is generally a very useful metric and so for attest to gain some real traction needs to support it.

Doesn't it though work to simply do coverage run runtests.py?

If so I still should probably document it.

With the new attest command it isn't obvious how to measure coverage. These should work:

coverage run -mattest
coverage run $(which attest)

These solutions should be documented as well.

Running coverage run -mattest gives me this error: no such option -m. My attest version is 0.5.2.

You are quite right, I noticed this too. The coverage docs claim -m is supposed to work but I get the same error. It does however work fine if you point it to a scriptfile that runs the tests.

This issue is now resolved upstream in the latest coverage.py relase.
