I don't think it's worth doing this in the tests. The hash table at least in case of the node name detection code is just an intermediate step to fill the data into the domain definition and it's a conveniet place to test the detection code. Testing it in other places would remove the dependency on deterministic ordering of the hash table but would not really add much value. The cost would be much more complexity in the test case which I don't think it's worth. If you feel bothered by it, please post patches. I think currently the testsuite tests the complex portion of the code without the bloating necessary for the so-called "clean" solution.
