Trapeze generates a suite of unit tests or specifications for existing Ruby source code. This is accomplished through dynamic analysis, by reflecting on the public interfaces of classes, modules and top-level methods defined in the source. Trapeze then exercises each object, module and method, recording the behavior of the code. This recorded behavior is captured in a suite of test cases or specifications that can be rendered as test code or executable specifications.
In essence, Trapeze is a tool for characterizing Ruby source code. Trapeze lets you fly high as you maintain and enhance a Ruby codebase that lacks test or spec coverage, knowing that you have a regression safety net underneath you.
