Python Testing with pytest

Review

In this chapter, we used coverage.py and pytest-cov to measure code coverage and used quite a few commands and options.

For running coverage with pytest-cov, use:

• pytest --cov=cards <test path> to run with a simple report

• pytest --cov=cards --cov-report=term-missing <test path> to show which lines weren’t run

• pytest --cov=cards --cov-report=html <test path> to generate an HTML report

For running coverage by itself, use:

• coverage run --source=cards -m pytest <test path> to run the test suite with coverage
• coverage report to show a simple terminal report
• coverage report --show-missing to show which lines weren’t run
• coverage html to generate an HTML report

Even if you ran coverage from pytest --cov=..., you can run different reports or generate ...
