What are some examples of using coverage.py with rc files?

Coverage.py is a tool for measuring code coverage in Python programs. You can use a .coveragerc file to configure its behavior. For example, you can specify which files to include or exclude from coverage reports.

Can you show me a sample .coveragerc file?

Sure! Here's a simple example of a .coveragerc file:

[run]
branch = True
source = my_project

[report]
omit = tests/*

This configuration enables branch coverage and specifies that coverage should be measured only for the my_project directory, omitting the tests directory from the report.

How do I run coverage with this configuration?

You can run coverage with the command coverage run --rcfile=.coveragerc -m pytest to execute your tests while using the specified configuration.

What if I want to generate an HTML report?

You can generate an HTML report by running coverage html --rcfile=.coveragerc. This will create an htmlcov directory with the report.
