The Rangers have been hard at work lately putting together guidance for good practices for organizing real world test efforts and how our tools can help. If you’ve got a significant test effort and are using the Visual Studio tools, I recommend checking this out.
Test Release Management – covers guidance on managing test practices and artifacts around release boundaries.
Test Tooling Guidance – covers guidance on how to organize coded UI tests for large apps, helping you componentize your UIMap so that it is not too unwieldy.
Hopefully you will find them useful.
