but won’t the tests also change for the same reason that they want to be flexible with types: because requirements and you realize might be going down the wrong path? Which is why I think they want that flexiblity with types. But with TDD, you also face the same issues. Unless they have never had to change their tests or delete them because they are useless at a point.
