[TIP] Can coverage.py be used to collect coverage data for Functional or integration tests?

Hi Florian,

Suppose my framework gets initiated when I execute if from command prompt.

For eg – Framework binary file is – agave. So we run like this –

Agave <tests> <test_args> <other_options>

My question is how do I invoke it from coverage.py?

The tests are designed in such a way that they can only run inside the framework. Python compiler is not enough to run them.

So only option left for me is to integrate coverage.py with my framework.
