Usando GMock para verificar un destructor de llamadas

Question

El uso de GMock, ¿cómo puedo comprobar que el destructor de una clase se llama? ¿Hay una manera, que no sea a envolverlo en otra clase ?

El método obvio, EXPECT_CALL(object, ~classtype()) produce un error de compilación (gmock no puede producir un método mock llamado gmock_~classtype).

Answer 1

An easy way to check for a destructor call:

class MockFoo : public Foo {
  ...
  // Add the following two lines to the mock class.
  MOCK_METHOD0(Die, void());
  virtual ~MockFoo() { Die(); }
};

In your test function:

 MockFoo* foo = new MockFoo;
  ...
  {
    EXPECT_CALL(*foo, Die());
  }

Answer 2

Unless you're passing --gmock_catch_leaked_mocks=0, then gmock should already be detecting when you fail to destroy a mock. The destructor is where unsatisfied expectations are flagged as errors, so gmock has special support for detecting when it is not called.
