title: TeamCity - Stop build when a test fails
body: <p>Is it possible to stop a TeamCity build (the entire build, i.e. it won't execute subsequent steps) when a unit test fails?  Ideally I'd also like it to terminate the currently executing step which in my case would be the Nunit Test Runner.  In my circumstance there is no point in continuing the build if a single unit test fails.  I've looked at Failure Conditions but I don't think they are applicable as the build continues to run.</p>
