How-to¶

Short recipes for specific tasks: one problem, one worked answer, no build-up. Each page assumes you have read the Guide and know what a fixture, a scope and a mark are.

Where the Guide teaches a concept at a time, a recipe here starts from something you want to accomplish — sharing a database engine across a suite, sharing code across test files, tuning concurrency from a --durations report, pinning down a flaky test, measuring coverage — and walks the code that does it.
