Coverage filter

Allows developers to indicate which code they are trying to test when using coverage tools.

Warning This is just a proof of concept. The API will likely change as I receive feedback. There are also no unit tests, or other code quality control methods in place. If you wish to use this code, please make a copy for yourself, so my changes won't break your build.

Example

Example code to be tested: (in target.py)

def target(self):
    return target_inner()

def target_inner(self):
    return 42

Example unit test: (in test_target.py)

from coverage_filter import CoverageFilter
from target import target

@CoverageFilter('target.py:target')
def test_target(self):
    assert target() == 42
