Gurock Software offers this Ruby library for accessing their TestRail API. TestRail is a test case and project management application for QA and development teams. This library offers full access to the API's functions like: creating test runs, synchronizing test cases between systems, and migrating test cases over from older systems. Their extensive documentation includes code examples and instruction for implementing the API. The TestRail API uses HTTP basic authorization and requires a TestRail username and password.
