Temporal Python Testing

Testing Temporal workflows properly requires understanding three distinct approaches: unit tests with time-skipping that can run month-long workflows in seconds, integration tests with mocked activities to isolate workflow logic, and replay tests that validate determinism against production histories. This skill walks you through pytest fixtures, WorkflowEnvironment setup, activity mocking patterns, and local development configuration with Docker Compose. The progressive disclosure format means you load specific resources based on what you're actually trying to test rather than wading through everything at once. Honestly saves you from the trial-and-error phase of figuring out Temporal's testing paradigms.
