@effect-temporal/testing

Testing helpers for @effect-temporal/workflow.

This package provides scoped Effect constructors for Temporal test servers, workflow clients, workflow engines, and workers. Client helpers use @effect-temporal/client, while workflow engine and worker helpers use @effect-temporal/workflow. The helpers use @temporalio/testing and automatically wire the test environment address and namespace into the package services.
