People’s opinion of what is needed for TDD differs widely. The so called xUnit testing frameworks are generally quite basic (test specification, assertions and test runners) but suffice for many people. They typically cannot be easily used to test GUI code. Other testing frameworks, it seems especially in the JavaScript world, extend much farther with test doubles, code coverage, and testing user interfaces via the browser. I have published a simple test framework, Mini-Test. It can be used to test both LiveCode handlers and GUI interfaces. (This is latter is a credit to LiveCode’s features not me). It is rooted in MiniTest, the testing framework included with Ruby. It does not include test doubles, code coverage or performance testing. LiveCode, the company, has a test framework but, personally, I found it too complicated for my own use. I felt something written wholly in LiveCode would be easier to handle.

I feel that the LiveCode engine makes it extremely easy to write a test framework that will do all of the above. It just needs a little thought, such as designing a set of commands to automate user input simulation, and a little work.
