Is your feature request related to a problem? Please describe.
Unit test stubs are being updated to pass-through a more complete context information, currently for EVS events such that the full spec string and argument set can be checked/manipulated.

Describe the solution you'd like
Sample unit tests should include an example of how to obtain the context arguments in a hook function.

Additional context
