That's E2E test. What's interesting with unit tests is that you can run them locally, offline. They are fast enough so that you can run them and see if you broke anything. If your tests take too much time to start or relies on a live env (which may be down or broken), you'll spend more time for maybe nothing.

With Docker I can run my E2E "offline".

If you're touching real data, your test isn't offline.

Not true. You might be touching local sample of real or realistic data. It does not need to be static either.

The performance of such a test is still a problem.
