I recently developed a utility tool for my application called batch-checkbox-util.js and I am eager to conduct some tests on it.
Although I have written a test script, which can be found at the same link provided, I am encountering an issue during the test execution. The error message indicates that the controller is not available, specifically the controller being utilized by a child directive within the parent directive.
Uncertain of the root cause and consequently the remedy, however, in order to resolve the current issue, I had to mark the parent directive as optional ?^. It is possible that during tests, there may not be sufficient time for it to load.
Once again unsure of the rationale behind it, but following the modification, the directive now needs to verify the presence of the controller or throw an error to indicate that the controller is currently unavailable.
