Temporal workflows coordinate long-running, fault-tolerant business processes. Testing them requires a different approach than testing regular functions — workflows encode history, run across multiple servers, and must be deterministic across replays. Why Temporal Testing Is Different A Temporal workflow is a durable function that can pause, resume after failures, and replay

Temporal and AWS Step Functions both orchestrate distributed workflows. But they differ significantly in how easy they are to test. This comparison covers unit testing, local development, mock support, replay testing, and CI integration. The Core Difference Temporal workflows are code. You write Go, Java, Python, or TypeScript. Tests use

Temporal activities are where your workflow touches the outside world — HTTP calls, database writes, email sends. Testing workflows in isolation means replacing activities with mocks that return predictable values without making real external calls. Why Mock Activities Activities in Temporal are the "impure" part of the system — they
