Thanks for everyone attending my " Implementing an Agile Software Development Process with Team Foundation Server (TFS) " presentation today. We enjoyed some good discussion. I had a few TFS-related questions pop up which I thought I'd address in a post: Q. Is it possible to fail the build but only if a specific test fails? So, let's say we have 3 tests. If Test01 or Test02 fail, fail the build. If Test03 fails, don't fail the build. A. Not that I'm aware of. If any test fails in a build but compilation succeeded, that build lists a state of Partially Succeeded. With TFS 2008 SP1, we received a property to modify or control this behavior: TreatTestFailureAsBuildFailure. If true (false is the default), any test failure will set the build state to Failed (vs. Partially Succeeded). Nice write-up here . You might take the approach of creating two separate builds: one that contains all your tests and one containing just mission critical tests. Set TreatTestFailureA...
