The folks at Microsoft have posted a Troubleshooting Guide for Visual Studio Test Controller and Agent to the MSDN Visual Studio Team System – Testing forum.
“This guide is to help troubleshoot connection issues between Visual Studio Test Controller and Agent as well as remote test execution issues. It gives an overview of main connection points used by Test Controller and Agent and walks through general troubleshooting steps. In the end it provides a list of common errors we have seen and ways to fix them, and a description of tools that can be useful for troubleshooting as well as how to obtain diagnostics information for test execution components.”
This guide lists the permissions, ports and topology of the Test Controllers and Agents that are new in VS 2010 as well as Step-by-Step troubleshooting sections.
They are also looking for feedback from the community on how to make the guide better. Just post a comment to the Guide’s thread. Good Stuff!
