TFS build server creates no test results

Question

Is there any way to activate a test related log at our TFS build server? If a tests fails, I can't find any information about it (besides the name of the test).

I checked:

• The drop folder. There is the normal log, but this log ends after the compilation, so before the tests are checked
• The compilation folder at the build server (C:\\Builds\\8...). There is a folder "Test Results" next to the "bin" and the "src" folder, but the "Test Results" folder is always empty.
• The build definition. Couldn't find any option to activate a log regarding tests.

When i check the build in the web view, all I see is:

x/y test(s) passed, z failed, 0 inconclusive

No Code Coverage Results Other Errors and Warnings z+1 error(s), 0 warning(s)

Failed z1 Failed z2 ... Failed zn Test Run Failed.

How can I find further information, why the tests are failing?

We are using:

• TFS 2012 + a TFS 2012 build server
• Rolling builds
• Visual Studio 2013 + Resharper at our local machines
• NUnit + MOQ
• Rolling builds (no more than 30 minutes) build definition

Answer 1

We got rid of the problem after we upgraded to TFS 2015. Now I just have to check the web interface, if a build is broken because of a unit test I click at the specific build to open the detail view of it. At the right side there is an area named Test result, where I can click at a link to get to the Test Run page. Under Attachments (1) I got a file of the type Visual Studio Test Results File , which shows me exactly what the problem was.
