Outside Smalltalk, TDD has never "worked" for me. But in a Smalltalk environment it was an absolute no-brainer and super slick because the environment was set up for it to just work. The nuance is the code-build-test cycle. In Smalltalk, they were all one and the same. In other languages and with other VMs, that cycle is disconnected. Likewise, once we moved to web applications, things changed. Now the unit we want to test is the API, or the widget, not really the function per se, but every TDD tradition has been at a much lower level. It overlooks that it takes real time and energy to build out tests at that higher level, and there are better tools than what have traditionally been "TDD."
