• What is the cause and solution for SAP error message ESH_TST_SMK_MSG031 - Unit test already running in another session ?

  The SAP error message ESH_TST_SMK_MSG031 indicates that a unit test is already running in another session. This typically occurs in the context of SAP's testing framework, particularly when you are trying to execute a unit test that is already being executed in a different session or by another user.
  Cause:
  
  Concurrent Execution: The most common cause of this error is that the same unit test is being executed in another session. SAP does not allow the same unit test to run concurrently to prevent data inconsistencies and ensure that the test results are reliable.
  Session Management: If a previous session was not properly closed or terminated, it may still be holding onto the execution context of the unit test.
  Locking Mechanism: SAP uses a locking mechanism to prevent multiple instances of the same test from running simultaneously.
  
  Solution:
  
  Check Active Sessions: Verify if the unit test is indeed running in another session. You can do this by checking the transaction SM50 (Process Overview) or SM66 (Global Process Overview) to see if there are any active processes related to the unit test.
  Terminate the Other Session: If you find that the unit test is running in another session and you have the necessary permissions, you can terminate that session. Be cautious when doing this, as it may affect other users.
  Wait for Completion: If you do not have the option to terminate the other session, you may need to wait until the other unit test execution completes before trying to run your test again.
  Review Test Design: If this issue occurs frequently, consider reviewing the design of your unit tests to ensure they can run independently without overlapping execution contexts.
