Increasing VSTS limit on old test run results

By default, Visual Studio Team System will only save 25 of your test run results. To increase this number:

1. Tools -> Options -> Test Tools -> Test Execution


2. Change the value after "Limit number of old Test Results to:"

Note: you still may have a practical limit if you use the freely included SQL Express (default). I think the artificially imposed limit is something like 5GB, not sure.
