I didn't mean to start a big discussion so I'm not ready to state or develop my vision right now fully and logically� But let's try to start little-by-little.�

Considering Pharo as an example� there are �few minor issues like lack of some code-producing features in debugger� the one I can remember right now is lack of code formatting there, but there are few more. Fixing such issues would be a first step towards TDD-oriented environment.�

Next steps would be about some more serious improvements: Test Runner improvements, auto-test running (it's already is implemented I think?), test annotations (expressing ideas behind every tests, relations between them, etc.), better test navigation and, perhaps, a "TDD-oriented" browser. Then, there should be introspection tools that for example silently save all the history and allow to review, analyze the development process regarding the idea-test-implementation triplets��

�Sure, I rather have a "feeling" of the TDD-oriented environment then a good proposal right now. The feeling grows to something almost reasonable when I code, but I didn't have such chance for few months already, so I'm kinda caught off base :)

Why do you think Smalltalk environments aren't "TDD oriented"? What
would an IDE need to be TDD oriented? (I can think of something like
Ruby's guard, which runs tests every time you save a file.)
