Is this compatible with existing CI/CD pipelines?

Yes, it includes guidance for setting up Temporal test environments and Docker containers in CI/CD, ensuring your workflows are validated automatically on every pull request.

How does time-skipping work with this skill?

It utilizes the Temporal Python SDK's WorkflowEnvironment to advance internal clocks manually, allowing you to execute and validate month-long workflows in milliseconds.

Can I use this for production determinism checks?

Yes, the skill includes specialized resources for Replay Testing, which validates your code against actual production history to prevent non-deterministic errors during deployment.

Does it support activity mocking?

Absolutely. It provides specific patterns for isolating workflow logic by mocking external activity calls using standard Python mocking libraries and integrated pytest fixtures.

Security & Testing

Streamlines the testing of Temporal workflows and activities using pytest, time-skipping, and mocking strategies.

About

This skill provides a comprehensive framework for testing Temporal workflows in Python, enabling developers to validate distributed systems logic with high confidence. It offers specialized guidance on unit testing with time-skipping—turning month-long workflows into seconds of execution—as well as integration testing with mocked activities and replay testing to ensure determinism. By providing ready-to-use patterns for local setup, pytest fixtures, and CI/CD integration, it helps development teams maintain high reliability and achieve over 80% code coverage in their Temporal applications.
