Integrating automated testing tools with TestRail and having an API to push test results is a popular feature request that we receive regularly. We have big plans in this regard and we are going to publish a new TestRail roadmap for the second half of 2010 at the end of the summer.

Until we have a complete API and support for automated testing tools directly integrated in TestRail, the mini API is a great way to submit your test results. You can download the API and learn more about its usage on the project site:
