Testing workflows and activities in Go requires a deep understanding of the testsuite package, which provides a mocked environment with deterministic time-skipp
Testing Strategies for Temporal workflows in Go provide a structured approach to validating workflow logic, activities, signals, and query handling using the `testsuite` package. It enables time-skipping to simulate long waits instantly, mocks external dependencies like activities and child workflows, and verifies determinism through replay testing. This skill ensures workflows behave as expected before deployment, reducing runtime errors and improving reliability.
This skill is essential for Go developers building Temporal workflows who need robust test coverage for complex distributed processes. It suits performance marketers and growth leads working with engineering teams to ensure customer-facing workflows handle edge cases and failures gracefully. Agency strategists managing integrations or automation pipelines will also benefit from understanding how to validate signal and query interactions within workflows.
Start by setting up the `WorkflowTestSuite` to maintain test state across multiple scenarios. Register mocks for activities and child workflows before executing the workflow under test, leveraging time-skipping to speed through delays. Use the `TestActivityEnvironment` to isolate and verify individual activities, ensuring they return expected results or handle errors correctly. Finally, run replay tests with saved workflow histories to confirm code changes do not break existing workflows and test signals by sending them at specific simulated times to validate state changes.
How do I simulate long delays in workflow tests? Use the built-in time-skipping feature in `testsuite` to advance workflow time instantly, even through waits of days. Can I test workflows that depend on external APIs or databases? Yes, mock all such activities to avoid real calls during tests, ensuring deterministic and fast execution. How do I verify that my workflow changes won’t break running workflows? Perform replay testing by loading historical workflow executions and re-running them with the updated code to check for determinism.
Attach this skill to a Metaflow agent task by specifying your Go-based Temporal workflows and activities for testing through the `testsuite` framework. Expect fast, isolated execution of workflow logic with comprehensive mocking and time control, enabling rapid feedback on workflow correctness and error handling. This skill integrates seamlessly into CI/CD pipelines to maintain workflow quality before production rollout, and...
