pytest-coverage
Exécute pytest avec rapport de couverture pour identifier et éliminer les lignes de code non testées. Génère des fichiers source annotés dans le répertoire cov_annotate/, avec des marqueurs ! indiquant les lignes non couvertes. Prend en charge les vérifications de couverture par module via --cov=module_name et les exécutions de tests ciblés sur des fichiers de test spécifiques. Flux de travail : exécuter la couverture, examiner les fichiers annotés pour les lignes non couvertes, écrire des tests pour combler les lacunes, répéter jusqu'à atteindre 100 % de couverture.
npx skills add https://github.com/github/awesome-copilot --skill pytest-coverageThe goal is for the tests to cover all lines of code.
Generate a coverage report with:
pytest --cov --cov-report=annotate:cov_annotate
If you are checking for coverage of a specific module, you can specify it like this:
pytest --cov=your_module_name --cov-report=annotate:cov_annotate
You can also specify specific tests to run, for example:
pytest tests/test_your_module.py --cov=your_module_name --cov-report=annotate:cov_annotate
Open the cov_annotate 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 cov_annotate 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.
