In case when Test Suite is created, but default Test Case constant is not replaced by "real" test case class, the following error is dropped while calling VI Tester window:
As the result - VI Tester window is empty, and does not list other test cases/test suits.
This error could be either handled somehow so user could see other tests; or error message will be more specific (like, that test suite does not contain valid test case class).
