Google Test中没有模拟的EXPECT_CALL

Question

Is there any way to test a function call via GoogleTest for c++ without creating mock object, eg we have the following production code:

if (a)
    method(x);

I would like to test whether the method will be called in the case a is True and a is False. I would like to construct a test that does exactly the same what Google Test's EXPECT_CALL does, but EXPECT_CALL works only with the mock object's method. In my case I would prefer not to use a mock (there is no need to create any object).

Answer 1

As state here ,

It's possible to use Google Mock to mock a free function (ie a C-style function or a static method). You just need to rewrite your code to use an interface (abstract class).

Their "It's possible" is misleading, as you have to rewrite code to use class (abstract, or provided by template), and so no longer use free functions.

Answer 2

If you are trying to fake a free function, you may want to look into the Fake Function Framework (fff) . It allows you to replace free functions with fake implementations that can be used in a similar way to GoogleMock.

It works seamlessly with GoogleMock and GoogleTest.
