Test Coverage

We do not include test coverage as a metric or a requirement in CI but test coverage as a local tool is useful to make sure your code does test all the things you care about.

To use it, install coverage in your virtualenv env.

pip install coverage

Now run the tests with coverage like this:

coverage run -m pytest normandy

To generate a report, run:

coverage html --skip-covered

This will create the HTML report in the ./htmlcov/ directory.

open htmlcov/index.html


The --skip-covered flag means it doesn’t create a HTML report for files with 100% test coverage.
