They appear when the tests are run with the `Wextra` flag.
I know of 3 possible solutions:
* A.) `static_cast<void>(unusedParameter);` – the preferred C++ way, but `unity` can also be used with `C`
* B.) `(void) unusedParameter;` – "old" C–style casting – the one I used – compatible with both C and C++
* C.) remove `unusedParameter` var from the function arguments – but keeping the name better explains what it is
