Can you add some test cases like testPartitionState and testNonPartitionState?

Can you add some test cases like testPartitionState and testNonPartitionState?

I've added, but find that there's a test overtime after upgrading the image to 3.2.0, and I can adjust the sequence to work properly, but this may be a potential bug, I'll try to locate to specific reasons.
