title: Xcode UI Tests - Stop testing when any given test in the test suite fails?
body: <p>I want to run my UI tests in such a way that if any given test within a test suite we're to fail, the entire test run is stopped. I understand there is an option to continue after failure, but this only applies to a single test case.</p>
  
  <p>I plan on running the UI tests on a CI server such as Teamcity, naturally I want the build process to fail if any of the tests fail without having to wait for remaining tests to complete. Does anyone know if this is possible or will I need to somehow parse the output of each test case to detect a failure and stop at that point, possibly with some exit code?</p>
  
  <p>Thanks.</p>
