I know that sounds strange but that is how it is)
I'm using MSTest to run my unit tests. Using VS2013 + ReSharper 8.1 + some dll projects in C#. I'm calling some API functions, that is why I need VS to running as Administrator or those calls will fail.
The problem is:
For some reason folder TestResults is empty. While tests are running and not completed, I can see a new folder (User_Comp YYYY-mm-dd HH-MM-ss) created inside, with all test outputs, but once tests are completed this folder is deleted, so TestResults are empty.
I've checked my project Options->Web Performance Test Tools->Test Execution->Limit number of old Test Results is set to 25. I've tried to disable ReSharper UnitTesting + disabled support for MSTests, NUnit and JS, but problem still exists.
When VS is started under normal account (not Administrator)
In this case folder "TestResults\User_Comp YYYY-mm-dd HH-MM-ss" is not deleted after test. Of course in this case some of my tests are failing.
I've set full access for each user to folder "TestResults" but still results are removed.
Looks that VS is using 0 as limit for Test Results. Did anyone face this problem?
Test results are removed when all tests pass. If any is failed, results are not removed.
Have you tried to add a *.testsettingsfile to your Test project in Visual Studio?
Have a look at https://msdn.microsoft.com/en-us/library/jj635153.aspx and specifically the "DeleteDeploymentDirectoryAfterTestRunIsComplete" setting
