When it comes to your code, no matter what type of development and testing philosophies you adapt, there is always the possibility that there can be holes in your attempts to reduce defects and improve maintainability. For this reason, it is never a good idea to solely rely on one type of development and testing methodology.

Observation-driven testing (ODT), in conjunction with test-driven development (TDD), can help fill holes with its automated code behavior observation. Read this white paper to learn how, as a result of successfully applying multiple techniques, your code will be more constrained, more maintainable, and better tested.
