Gmock：保存传递参数的指针或在预期调用中按地址进行比较

Question

假设我有一个方法

void Mock::foo(const A& obj);

并且我想检查它是用对象 obj 而不是它的副本调用的：

A obj;

EXPECT_CALL(mock, foo(obj));

mock->foo(obj);

我该如何检查？我找到 Address(m) 匹配器 here。但我无法在 ::testing 中找到它，即它无法编译。

如评论中所述，::testing::Address() 匹配器是在 GoogleTest 1.11 中引入的。

您可以改用 ::testing::Ref() matcher, which does the same thing underneath (comparing addresses) and is available since at least GoogleTest 1.8 (see it online):

#include <gmock/gmock.h>

struct Data
{};

struct Mock
{
    MOCK_METHOD(void, foo, (const Data& d), ());
};

struct ClassUnderTest
{
    Mock* dependency;
    void methodUnderTest(const Data& d)
    {
        dependency->foo(d);
    }
    void methodThatCopies(const Data& d)
    {
        Data copy = d;
        dependency->foo(copy);
    }
};

TEST(X, Correct)
{
    Mock m;
    Data d;
    ClassUnderTest uut {&m};

    EXPECT_CALL(m, foo(::testing::Ref(d)));
    uut.methodUnderTest(d);
}

TEST(X, Fail)
{
    Mock m;
    Data d;
    ClassUnderTest uut {&m};

    EXPECT_CALL(m, foo(::testing::Ref(d)));
    uut.methodThatCopies(d);
}

int main(int argc, char** argv)
{
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}
