pytest-coverage
Jalankan pytest dengan laporan cakupan untuk mengidentifikasi dan menghilangkan baris kode yang tidak teruji. Menghasilkan file sumber beranotasi di direktori cov_annotate/, dengan penanda ! yang menunjukkan baris yang tidak tercakup. Mendukung pemeriksaan cakupan spesifik modul melalui --cov=nama_modul dan pengujian tertarget pada file pengujian tertentu. Alur kerja: jalankan cakupan, tinjau file beranotasi untuk baris yang tidak tercakup, tulis pengujian untuk menutupi celah, ulangi hingga cakupan 100% tercapai.
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.
