temporal-python-testing

Test Temporal Python workflows and activities using unit, integration, and replay testing methodologies. This approach covers local development setup with Docker Compose, pytest integration, and coverage strategies to ensure production-ready code reliability.

Replay testing validates Temporal workflow determinism and backward compatibility by replaying production histories. You need it to ensure safe deployment and prevent non-deterministic errors when updating workflow logic in existing Python applications.

Set up a local Temporal environment for Python testing by configuring a local Temporal server using Docker Compose. This enables seamless local development, allowing you to run unit and integration tests efficiently before deployment.

Yes, you can use pytest with Temporal Python workflows for integration testing. Validate workflow orchestration by mocking activities and injecting errors to ensure your Python workflows handle external dependencies and failures correctly.

Unit test Temporal activities in isolation using Python by applying the ActivityEnvironment for rapid feedback. This allows time-skipping to test individual activities independently before building broader integration tests for external dependencies.

The best way to validate Temporal workflow determinism in Python is replay testing. Replaying production histories ensures your workflows remain deterministic and backward compatible, guaranteeing safe deployment of production-ready code.
