test_dynamic_state_insertion unstable

[franzlst]

The test_dynamic_state_insertion is unstable. The dynamic_library_insertion parameterization is stable, the other two are not.

Till the test is fixed, it is marked as unstable.

The following stacktrace occurs often:

Also the first parametrization (dynamic_library_insertion) is unstable.

This is the underlying error, causing the AssertionError:

00:03:47.550 AssertionError

So a LibraryState is created (dynamically in the execute function of an ExecutionState) and passed as state to ContainerState.add_state. However, at that point assert isinstance(state, State) is not fulfilled.

I tried hard, to find out why this is, but did not succeed. One problem is that I cannot reproduce this locally on my machine.
