You’re entirely right that running a bunch of tests is a really effective way to advocate for better resources to run the tests. While I’ve never worked anywhere that ran out of ideas to game the testing incentives, it’s definitely true that people who initially fall into the trap of gaming the tests come around with some experience and in general the org builds better intuitions and culture around how to use tests.
It may be that an org that _has_ a culture of testing just has them constantly running in the background but they’re minor in terms of time spent running them, but that building a culture of testing initially involves the whole org focusing on it to a seemingly ridiculous extent, as it’s the only way to generate enough momentum to get the infrastructure and institutional knowledge right.
