Can we agree that "it depends"? If I have a resource-starved build runner (looking at you, there, Bitbucket Pipelines), and I have a good handful of parallel integration tests, each spinning up a few Docker containers worth of dependencies, I will end up troubleshooting out of memory situations. I also don't think you get to leverage application context caching, for parallel test execution, and if you did, I'd be concerned about unpredictable conflicting state between those integration tests. If I can already run my tests for a single microservice in about two minutes, the parallelization just isn't worth it to me (in CI). And, oh, I'm not in a monorepo.
