Right-clicking on a VI in a project and selecting "Find -> Callers" doesn't list any .lvtest files which call the VI in question. I think there should be a relatively easy way to find which unit tests call the VI. I use Find -> Callers when I'm refactoring, and want to know what code might be impacted by a change. It'd be nice to quickly find the unit tests which also call the VI.
Option 1) Have Find -> Callers include .lvtest files in the results alongside calling VIs.
