That’s why I laugh when people are like “oh, AI writes all the tests, it’s so much easier.” If your code is hard to test, you need to change the abstraction or the interface. Tests are the first reuse of your code, so if it’s a pain to use in tests, it’s going to be terrible to use in general.
This is why I teach TDD when I'm teaching agent use to my clients.
Not to mention that tests are at least as critical to get right as the code that is being tested.
And not to mention that most tests available to AI training is trash, so no wonder AI-generated tests are not only worthless but costly in terms of false sense of reliability.
