I am writing tests. I want to verify completed workflows as in the expected workflows were successfully executed/failed etc

To complete a scenario (migration of data) in current use case, I want to assert completion/failure of workflows or may be complete history.

Is this possible? I was looking into documentation and found `QueryWorkflow` but it seems it is for running workflow and not completed workflows.

Thank you

A `client.GetWorkflow(...)` returns a future that, if you `Get(...)` on it, it will either unmarshal the result into the second param and return no error on success, or return an error if the workflow failed.

You can absolutely execute a query on a completed workflow (I can provide a brief explainer on how this works if desired). It is a normal thing to do. Usually you’d count on the workflow result or error to relay completion info, but you can use a query to relay status which is especially useful if you also want to call while the workflow is running.
