For this recipe, we require three files. The first is the implementation that we wish to test (we can call the file leaky_implementation.cpp):
#include "leaky_implementation.hpp"int do_some_work() { // we allocate an array double *my_array = new double[1000]; // do some work // ... // we forget to deallocate it // delete[] my_array; return 0;}
We also need the corresponding header file (leaky_implementation.hpp):
#pragma onceint do_some_work();
And, we need the test file (test.cpp):
#include "leaky_implementation.hpp"int main() { int return_code = do_some_work(); return return_code;}
We expect the test to pass, since the return_code is hardcoded to 0. However, we also hope to detect a memory leak, since we forgot to de-allocate ...
