The thing that frustrates me is running into situations where creating the infrastructure and code to set up and run a test is orders of magnitude more complicated than actually building the application. This is typically not at the unit test level (which mostly isn't that bad), but rather at the "wow, I basically need to implement a local version of this 3rd party API that doesn't have a test environment" sort of level. And that's not even getting into the times I've had to work with "APIs" that are so bad they aren't even testable (wishing wells).
