Guides

Task-oriented how-tos:

• Migrating from pytest — the drop-in story
• Migrating from pytest-xdist — flag map and differences
• Parallel safety — rails for tests that can't parallelize
• Suite diagnostics — reading --doctor
• Flaky tests — reruns, flake history, quarantine
• Watch mode — the edit loop
• Selecting changed tests — --changed via import graph or coverage index
• Monorepos — one command across a multi-package repo
• CI quickstart — GitHub, GitLab, Azure, CircleCI, Jenkins, cloud builders, JUnit, caching, pre-commit
• Plugins — how plugin loading works, what's verified
• Coverage — pytest-cov under parallel workers
