> I've left most of the tests out of the scope of this review to provide more confidence; however, I've fixed them in a few places where using sets consistently broke things. Specifically I changed construction of some Thrift structs to use set-literals instead of list-literals (since their IDL type is set and not list) and this broke some tests due to a long-standing bug in Thrift.

> To fix them I've introduced a test dependency on [PyHamcrest](http://pyhamcrest.readthedocs.org/en/release-1.8/tutorial/) for matchers support (it's pretty much the same as Java for those who are familiar). Usage of PyHamcrest is [suggested in the mock documentation for this use case](https://docs.python.org/3/library/unittest.mock-examples.html#more-complex-argument-matching).
