I have been interested in starting to use unit tests to validate development. In my current job, we do a lot of green screen development for the Multi-Value database environment. There did not seem to be any good options for implementing unit tests in this environment. At work, we just had a presentation on mvTest by Brian Leach. Brian has developed a tool for doing unit tests in green screen environments. It is similar to how Selenium uses a web driver to drive a browser through a site and look for output in a web page to confirm the processing except this encapsulates a telnet session and looks for screen changes. It is an effective way of implementing unit tests in a green screen environment. I am looking forward to getting the chance to work with it.
