I think it's going to largely depend on build times and how much infrastructure you need to spin up during during tests. Some discussion for the same question in a recent thread: https://news.ycombinator.com/item?id=21679714 https://news.ycombinator.com/item?id=21679714 We're quite a bit smaller but have similar numbers: 15-20m right now. We're dominated by build time (build caching might help) and schlepping docker images.
