I can create and execute test cases

[saig0]

Is your feature request related to a problem? Please describe.
As a user, I want to create test cases for my processes to verify that the processes behave as expected.

Describe the solution you'd like
I want to create test cases for my process visually on the diagram.

I want to execute the test cases and see if the processes fulfill the expectation. If not, I want to analyze the test run.

Further ideas:

• import and export of test cases
• create a test case by recording commands (like in Selenium)

Describe alternatives you've considered
None.

Additional context
Requires camunda-community-hub/zeebe-spec#100.
