Interesting, haven't heard this before (I don't know much about testing). Is this kind of like fuzzing?

I recently had race condition that made tests randomly fail because one test created "data_1" and another test also created "data_1".

- Test 1 -> set data_1 with value 1

- Test 1 -> `do some magic`

- Test 1 -> assert value 1 + magic = expected value

- Test 2 -> set data_1 with value 2

But this can fail if `do some magic` is slow and Test 2 starts before Test 1 asserts.

So I can either stop parallelism, but in real life parallelism exists, or ensure that each test as random id, just like it would happen in real life.
