Having executed a test - at a minimum - we want to know the outcome. But beyond that, we may want to know more. Data collectors and loggers are the key extension mechanisms intended to provide this and other such details for rich reporting. Data collectors and loggers generate information based on listening to events raised during test ...

Updating off pre-RTM bits once RTM ships ought to be routine.

At its core, TIA collects, and subsequently consults, a map of the dynamic dependencies of each test method as it is executing. As the test method is executing it will cover various methods - the source file in which those methods reside are the dynamic dependencies that get tracked. So, the mapping ends up like the following: and so on...
