The ability to write test scripts for a graphical interface can be thwarted by an unfortunate GUI development tool choice. We've encountered such problems in several projects. When selecting development tools, it's important to consider how testable the interfaces they create will be. They tend to work very well in that context, but custom controls and widgets complicate their use. Moreover, customized interfaces generated by some development tools can stop these tools in their tracks, even though such interfaces may look like a manual interface to the casual observer.
