Environment
Problem
As shown here I decorated my TestMethod like
[TestCategory("Gated"), TestMethod()]
As shown here I filtered, like
TestCategory=Gated
When I build without any filter, the TestRun run successfully with all unit tests. But when I tried to filter over TestCaterory, no TestRun started at all.
I tried without success ...
... to put the filter in quotation:
"TestCategory=Gated"
... to separate the attributes:
[TestMethod]
[TestCategory("Gated")]
... a similar question has been posted here, but I can't revert back to using the old default.xaml.
... I found just one warning in the build log under "Run Visual Studio Test Runner for Test Sources": "Dependent Assembly Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed of C:\Builds2\56\614\bin\External\Microsoft.TeamFoundation.TestManagement.Common.dll not found. Can be ignored if not a NUnit project."
-> I added the reference to Newtonsoft.Json in every single NUnit-Project in all the solutions, that were build during the gated check-in - also without success.
The problem was not the TestCategory, but another pretty simple one:
The unittest-project in which the “broken” testmethod resides was not part of ”projects to Build” of the Build Definition.
