FAQPage Schema

How do I measure test coverage with pytest and identify untested code?▼

Test coverage measures which lines and branches your pytest tests execute. Use pytest-cov to run tests with coverage tracking, then generate reports showing missing lines and untested code paths. This reveals gaps in your test suite that could hide bugs.

What's the best way to enforce minimum coverage thresholds in my codebase?▼

Set coverage thresholds (e.g., >= 80%) and validate against them after each test run. Coverage analyzers check whether your actual coverage meets these targets and fail the build if thresholds are breached, preventing quality regression.

How can I identify which modules have the lowest test coverage?▼

Coverage gap analysis highlights modules and functions with low or zero coverage, ranking them by untested lines. This prioritizes where to add tests for maximum quality impact across your codebase or services.

Can I track coverage improvements over time and compare historical trends?▼

Yes. Multi-format reporting (HTML, XML, JSON) lets you store and compare coverage metrics across test runs, exposing trends in coverage growth or regressions and validating that test investments are paying off.

Does coverage analysis work for both unit and integration tests?▼

Coverage analysis applies to both unit and integration tests. It measures any code executed during pytest runs, supporting different test types and scopes from single modules to entire codebases.
