These are just logic tests, not integration tests with Instruments.
Took me forever to get the build to work. Per my other post for some reason xcodebuild did not work from the command line on TeamCity's installation though it did locally.
Now, it builds successfully then runs a .sh file and the simulator comes up on the screen of the server, but it's blank and it just hangs.
I tried starting the simulator through Xcode. Didn't seem to make any difference.
The build step is defaults with clean build as the commands, run tests checked and these parameters provided:
-configuration "Debug" -sdk iphonesimulator7.1
(I tried with just iphonesimulator as well.)
