Please note that the `THROW` family of assertions expects to be passed a single expression, not a statement or series of statements. If you want to check a more complicated sequence of operations, you can use a C++11 lambda function.
Expects that exception of _exception type_ is thrown and it matches provided matcher (see next section for Matchers).
