Kettled twice. Extra chewy, extra trustworthy.
Summary
Coverage.py utilizes regexes to define pragma syntax for excluding code from measurement, offering flexibility and power in its implementation. Unlike other tools with fixed syntax, Coverage.py allows users to modify or add regexes, enhancing its adaptability.
Key quotes
· 4 pulledCoverage.py lets you indicate code to exclude from measurement by adding comments to your Python files.
Rather than having fixed syntax for these comments, they are defined using regexes that you can change or add to.
This has been surprisingly powerful.
Coverage finds lines in your source files that match the regexes. These lines are excluded from measurement.
