What is it about the tests that make you not care about how it’s implemented versus other code? Just the fact that it isn’t interesting to you? I happen to like spec-testing code and find it an interesting design space. It is vital to review it thoroughly for correctness. But I also think that whether I find something interesting or not doesn’t have much bearing on whether code quality is important. Code quality can even be more important for uninteresting code, because due to the lack of interest I’ll have a lower attention span when reviewing it.
