It's a trade off for sure. I have seen people write test code with no regards to DRY and it results in tests that are hundreds of lines of setup trying to wire up the inputs and the expectations when a little bit of thought to remove all that repetitive code would go a long way in making the tests readable. I do agree that there doesn't need to be obsession with DRY when it comes to writing tests (esp when you are bouncing around multiple functions and files just to understand the testcase) but completely abandoning it either isn't great either.
