I can see how that'd be the case. For me, the thing I like about TDD is that I can clearly outline my expectation of how code should work so that it feels logically sound. And then, if I need to refactor it, I can confirm that everything is still ok. I would never want to refactor a big project that was only tested from public facing stuff. I think that if you need to mock stuff TDD can be slow and a pain. Almost all of my tests are expect().toBe();... there's almost nothing to writing them. I keep it deliberately simple because if it's hard to test, I'm probably writing brittle code. (Not to say you are or were either. Just something that I noticed about my own coding practice).
Nice! Different stuff works for different people. I find no value in writing individual units. Never have I ever caught a bug because a unit test failed. I did catch a bug because my functional test failed though.
Even recently. My test was written in a way such that I expected that if the user tried to access a class that didn't exist within a DI container, that the code would throw an exception. Turns out that the code was written such that if the DI container didn't contain the class it would throw an exception in php 7.1, but not 7.3. That is a bug that I wouldn't have been able to catch if I mocked everything and spent time writing individual unit tests.

Totally agree. Different strokes.
And I hear ya about the need for other tests and assurances too. I wouldn't ever think, "I have unit tests, so everything is perfect."
And I've written loads of code that isn't tested at all and had zero problems.
I can say this much. I DEFINITELY dislike TDD when working with OOP. :)
