The 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.
