Prove API sandbox isolation and reset

Parallel workers must never see one another’s created records and reset must restore the seed.

  • api
  • isolation
  • reset

Objective

What to automate

Create independent sessions, mutate one, prove isolation, then reset and verify seed restoration.

  • Open the fixture identified by FX-FORM-001, FX-TABLE-001.

Test data

  • session A customer: isolated.a@example.test
  • session B
