Contract testing isn't E2E testing and doesn't provide the same guarantees. So they are replacing a high cost, high value system with a lower cost, lower value system. So they are literally saying that they don't think the extra value of E2E testing is worth the extra cost. Personally, I think they are wrong, and the problems they have with their E2E tests are problems with their implementation. Fixing them would benefit the customer experience and the developer experience as well as reducing the costs of the E2E. They are absolutely going to have critical customer impact (they are fintech ffs) that their E2E tests would have caught. Of course, whether that actually tanks their business depends on other factors. So accepting more critical issues may the right thing for the success of the company. Robinhood customers were greatly pissed off by its behavior, and yet it doesn't seem to have hurt them too much. But I wouldn't fucking boast about it!
