Uber Cadence：如何断言对工作流的调用（Sleep（）？）？

In my unit tests, I want to assert that workflow.Sleep() was called. How do I do this?

It's possible to access the emulated time using the TestWorkflowEnvironment.Now() function. For example:

before := testenv.Now()
testenv.ExecuteWorkflow(...)
after := testenv.Now()

Then assert on the change between before and after.
