I am happy to announce that we have just released the third preliminary version of TestApi -- the testing API library. This version introduces some fairly significant changes and new features:
TestApi is a policy-free API library, delivering Microsoft testing technology in an easy to use package. It can be used from within any tool (VSTS, NUnit, xUnit, etc.) or environment to automate the testing for desktop and in-browse applications on Windows.
TestApi v0.3 is available on http://testapi.codeplex.com. Thanks for all your feedback. Keep it coming! :)
