The dogma around unit testing, TDD and the book selling test hype cycles have caused immeasurable damage to software development as technical and scientific disciplines.
Or how about another project that had lots of real tests, that were old, unmaintained, did humongous amounts of work in each single unit test and took a weekend to run, and of course, fail.
Or perhaps the team that obsessed about the testing for each user story, spent all the time doing that, then running out of time to deliver the actual stories.
And those were the less egregious examples!
