Code coverage

Configure coverage by editing .coveragerc:

[run]
branch = True

# coverage data file path
data_file = output/.coverage

# omitted file patterns
omit = mylib/tests/*, mylib/tools/*

[html]
# html report output folder
directory = output/htmlcov

Use pytest to measure coverage for mylib package:

coverage run --source=mylib -m pytest tests/

To generate html report:

coverage html

View output/htmlcov/index.html in browser.

Done.
