Pytest - Production test Coverage

Short summary

A practical guide to running pytest in production-grade CI pipelines, covering log configuration, marker-based test splitting, and honest code coverage. Key tips include using --log-cli-level for readable output, autouse fixtures to auto-skip integration tests, and ensuring all modules are imported so coverage reports don't silently inflate. Coverage is a floor, not a ceiling — a covered line ran, but may not have run correctly.

• •Configure pytest logging with --log-cli-level and caplog fixture for debuggability
• •Use markers and autouse fixtures to separate unit from integration tests in CI
• •Treat coverage as a floor not a ceiling; ensure all modules are imported to avoid inflated numbers
