Acceptance Testing: Can I pass terraform apply parameters to test runner?


I have a TestCase in my provider that requires that the resources in it are not created simultaneously, but in (any) order. Normally, there are two ways to force this:
1.) add -parallelism=1 to terraform apply
2.) add explicit dependencies with depends_on blocks between the resources so that terraform cannot create them in parallel

Now, obviously option 2 gets less convenient the more resources I create. But I do not see any option to implement option 1 in the TestCase.
