From the Catch docs: 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. https://github.com/philsquared/Catch/blob/master/docs/assertions.md In current versions of Catch violating this causes a build error.
