Note that is the python dictionary is unordered.

For example, the 'test_modules' may be {'a': 1, 'c': 3, 'b': 2, ...} or  
{'c': 3, 'a': 1, 'b': 2, ...} or ...

And then the 'type' has been sequentially executed by codes, for 


s/has/hasn't/.


example, type = "s4 migration" then the result
is 'migration' case is run firstly, it's not our expected, so we should 
use a list with 2-tupes instead of dictionary to
complete similar function, please check patch in the attachment.
