Improvement: Testing OwnerDetails#validate exit behavior

[Surya00011]

While working on unit test for OwnerDetails#validate method, I ran into a small complication:

• If entityType is invalid, the method ends up calling Main.exit(-1).

• Since this uses System.exit, it terminates the JVM immediately.

• That makes it difficult to write a proper test for this path, because the test process itself stops.

From my side, I just wanted to share this with you. Adding tests for this case isn’t straightforward without special handling. I thought it would be helpful for you to know, in case it comes up again.

Thanks @justinmclean

Yes, this issue was previously encountered and we came up with a solution. Take a look at some of the tests that use Main.useExit = false;

If you set this in a test, it will throw an RuntimeException exception rather than exiting:

 public static void exit(int code) {
    if (useExit) {
      System.exit(code);
    } else {
      throw new RuntimeException("Exit with code " + code);
    }
  }
