Path too long exception in MTM

Question

Trying to run CodedUI test cases using MTM: Several errors:

Test Run deployment issue: Failed to access the file 'C:\Users\master\AppData\Local\VSEQT\QTController\rm\1234\master_TestController 2017-07-28 08_10_50\Out\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\Architecture Tools\Providers\AssemblyMetadata\Microsoft.VisualStudio.ArchitectureTools.AssemblyMetadataProvider.dll': System.IO.PathTooLongException: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.'."

Answer 1

The best and easiest way to solve the PathTooLongException is tweaking the path space.

The test result in the test control is using the folder ...\VSEQT\QTController\rm\[run ID]\[name] [date]\..\... to store files before attaching them to TFS. This location's length is usually very long.

So users must handle the attachments' name to avoid long path exception. Or changing that default location. A solution is changing the QTController.exe.config "WorkingDirectory" in QTController.exe.config and make the path shorter.
