I very strongly disagree. Having "integration" tests are super powerful, you should be able to test against your interfaces/contracts and not have to spin up an entire environment with all of your hundreds of microservces, building "integrated" tests that are then dependant on the current correctness of the other microservices.

I advocate for not having any integrated environment for automated testing at all. The aim should be to be able to run all tests locally and get a quicker feedback loop.
