Code coverage measurement for Python
Coverage.py measures code coverage, typically during test execution. It uses the code analysis tools and tracing hooks provided in the Python standard library to determine which lines are executable, and which have been executed.
Coverage.py runs on Pythons 2.3 through 3.3, and PyPy 1.9.
New in 3.6: --fail-under, and >20 bugs closed.
New in 3.5: Branch coverage exclusions, keyboard shortcuts in HTML report.
New in 3.4: Better control over source to measure, and unexecuted files can be reported.
New in 3.3: .coveragerc files.
New in 3.2: Branch coverage!
