 # 🔁 workflows
 
-Unit testing of workflows themselves is not possible yet - but you can still
-trigger them in unit tests.
+This Worker includes two Workflows: a basic workflow that runs a single step and completes `TestWorkflow`, and a long-running worflow that includes more steps `TestLongWorkflow`.
+The testing suite uses workflow mocking to validate the logic of each step.
