@tdpauw thanks for writing this, gold.
From my observation every change in the tool chain e.g. Spring boot, Test containers and now AI, people try to (near) only have e2e tests and somehow miss that it slows you down by a lot.
IMHO Using Unit tests to guide your software design is an underdeveloped skill in these circumstances.

@mrksdck @tdpauw I’m a big fan of high-level “fast” tests that do everything in memory, stubbing out the ports+adapters but not testing individual classes/functions. My problem with a lot of these fully-E2E tests is that they’re slow and flaky!
