Mocking a void method?

[m-mcgowan]

I have a interface like this:

struct Change {
    virtual void change(uint8_t r, uint8_t g, uint8_t b) =0;
};

In a test code like

function assertChanged(Mock<Change>& mock, uint8_t v1, uint8_t  v2, uint8_t v3) {
   Verify(Method(mock, change).Using(v1,v2,v3));
}

TEST_CASE(...) {
Mock<Change> mock;
Change* change = &mock.get();
When(Method(mock, change)).AlwaysReturn();
change->change(1, 2, 3);
assertChanged(mock, 1, 2, 3);
}

But I get

Unexpected method invocation: unknown()
  An unmocked method was invoked. All used virtual methods must be stubbed!

What am I doing wrong?

You are doing nothing wrong. Actually I just added your test to the file default_behaviore_tests.cpp and it passes. It is part of Fakeit tests on github now. I guess this is a another MinGW issue. I'll check it on MinGW soon and give you an accurate answer. Thank,

struct Change { virtual void change(uint8_t r, uint8_t g, uint8_t b) =0; };

void assertChanged(Mock& mock, uint8_t v1, uint8_t v2, uint8_t v3) { Verify(Method(mock, change).Using(v1,v2,v3)); }

void testPassMockByRef() { Mock mock; Change* change = &mock.get(); When(Method(mock, change)).AlwaysReturn(); change->change(1, 2, 3); assertChanged(mock, 1, 2, 3); }

I have just ran the tests on MinGW 32 on my computer and your test passes. Can you please send me the exact details of the configuration you are using. BTW, I had to replace all std::to_string with my implementation fakeit::to_string since I got a compile error on MinGW32: error: ‘to_string’ is not a member of ‘std’. Don't you get this error too?

Did you get a chance to pull the latest version and run the tests? I added your test to the set of fakeit unit tests and it passes. Please try to build & run the tests. If they pass then all is OK. If not, please send me the output. Thanks,

All tests pass (including the above example one). On all GCC, Clang, MSC, & MinGWx32.
