I only write end to end tests. Because I come mainly from a maintenance background: unit test for test coverage are a hindrance. But testing functionalities of an app? That's what a client want. They don't care about how you implementing things, only that it works. And that old bugs don't come back. Yes it means new functionalities have higher estimates. But they tend to not come back once done. And doing it with end to end tests means you should easily be able to trash all the code and replace it with something else doing the same work. The problem is the tooling. Mocking external APIs tend to be a pain even with Wiremock. Testing a GUI is not easy: a Sikuli server to drive a GUI with screenshots would be a boon. And it tends to be slow. But that's because most of the work has been going to JUnit-like tests for years.
