[suityou01]

What are you really trying to do?

Unit test a workflow

Describe the bug

When unit testing a workflow, if the workflow under test encounters a runtime exception the unit test hangs.

Minimal Reproduction

See pull request here wolfy-j/temporal-simple-test-example#1

Environment/Versions

• OS and processor: [e.g. M1 Mac, x86 Windows, Linux] - Ubuntu Linux 22.04
• Temporal Version: [e.g. 1.14.0?] and/or SDK version - 1.23.1
• Are you using Docker or Kubernetes or building Temporal from source? - On the metal using Temporal\Testing\Environment

Additional context

Discussed on slack last Friday with wolfy-j

Try to limit Client requests by timeouts.

This would not give me the error details of the runtime exception but of the timeout thus masking the problem. It would also prevent any unit testing that expected specific exceptions.
