pytest-coverage

Run pytest tests with coverage, discover lines missing coverage, and increase coverage to 100%.

Why this skill is useful

Provides specific pytest commands and coverage reporting techniques that enhance the AI's ability to ensure code quality and test coverage.

What it needs

Requires pytest installed locally. About 1k tokens when loaded. Last updated 2026-08-07. 37,534 stars on the source repository.

What this skill does

The goal is for the tests to cover all lines of code. Generate a coverage report with: pytest --cov --cov-report=annotate:covannotate If you are checking for coverage of a specific module, you can specify it like this: pytest --cov=yourmodulename --cov-report=annotate:covannotate You can also specify specific tests to run, for example: pytest tests/testyourmodule.py --cov=yourmodulename --cov-report=annotate:covannotate Open the covannotate directory to view the annotated source code. There will be one file per source file. If a file has 100% source coverage, it means all lines are covered by tests, so you do not need to open the file. For each file that has less than 100% test coverage, find the matching file in covannotate and review the file. If a line starts with a ! (exclamation mark), it means that the line is not covered by tests. Add tests to cover the missing lines. Keep running the tests and improving coverage until all lines are covered.

How to use it
