In the team I lead, we haven't really shipped tests in over a year. We've also been in discovery and proof-of-concept phase, and where I do agree with the author is it's not worth it to spend tireless hours on having green pipelines at this stage. However we are now starting to put our platform towards a what will become a production state, and it's clear that without some level of testing, the confidence of stability is too low. (Thankfully our codebase is lightweight and mostly integration between systems, with some components for a third-party tool)
