It's called TDD not UTDD.

I frequently do TDD with integration and end to end tests. The type of test should be dictated by the nature of the code, which TDD doesnt have an opinion on.

TDD is about following red-green-refactor.

Good for you then. I myself have not come across the (loud/louder) TDD exponents advocating for using TDD in system/integration testing, they mostly focus on unit tests. If you can point to some examples, it would be a learning experience for me. If not that's fine too, I am glad that there are voices out there like yours.

I wrote a systems/integration testing framework for this purpose specifically and I wrote a few essays alongside it. It has the same name as my handle.

Not much traction, unfortunately. Id be interested in any comments you might have.
