How to write temporal test cases using Junit in Springboot Application?

2

It’s getting difficult to write junit testCases for worflow.

3

We don’t have direct Spring Boot integration yet.

You can still write unit tests using provided testing support.

4

In real use cases we have a separate class for workflow and activities.
In Activity level it is working, but in workflow level it is not working.

5

Please, provide information about the specific issue you are facing. It is hard to help based on “workflow level not working” description.

while executing the workflow unit test case. I am getting this error.

The error is:
Cannot subclass final class class io.temporal.workflow.Workflow

Are you trying to mock the Workflow class? Why?

8

Yes, for unit test cases I am mocking workflow for further process

This is not going to work. Please use the unit testing support provided by Temporal SDK.
