Engineers should absolutely be writing unit tests and integration tests for their APIs. Personally I find that it brings a lot more integrity and a sense of ownership into the process when engineers are required to deliver tests. I disagree with the problem's that you mention in this article: Developers aren’t incentivized to prioritize QA testing Developers are typically evaluated based on the quantity of software they ship, and how fast they ship it. That's an organizational problem that is not universal and certainly won't be solved by a QA automation tool. Developers’ job satisfaction goes down when they’re in charge of QA Expanding upon one of the previous points:, we’ve seen that most developers just don’t enjoy doing QA. This might be the case for manual testing but for automated testing the opposite is true. Delivering tests along with code increases integrity, makes debugging significantly easier, and helps clearly communicate the intention of each feature. This only works if there is collaboration between the developers and the product owner. Clearly you have a viable product that works for many organizations, but it's certainly not a one-size-fits-all solution nor a best practice.
