Hi Erik,

It is true that setting the dependency in the metadata will solve the 
problem.

However, I am concerned that depending (pun unintentional) on the 
implementation to properly order the deletes based on the metadata is 
using an advanced feature for simple test cases.

So in my opinion, it's better to explicitly put the deletes in the 
proper order for these tests and have a different explicit test for 
dependency.

Thanks,

Craig
