Testing involves finding problems in your code, while debugging consists of isolating and fixing the problems. Testing and debugging are necessary stages in the development cycle and are best incorporated early in the cycle. Thoroughly testing and debugging individual components makes testing and debugging integrated applications much easier.

When testing and debugging applications, developers typically look for different levels of robustness:

Visual FoxPro provides a rich set of tools to help you isolate and identify problems in code so that you can fix them effectively.
