Gmock - matching structures

Question

How can I match value of an element in a union for an input argument e.g - if I mock a method with the following signatiure -

    struct SomeStruct
    {   
           


        

Answer 1

This is basically answered above but I want to give you one more good example:

// some test type
struct Foo {
    bool b;
    int i;
};

// define a matcher if ==operator is not needed in production
MATCHER_P(EqFoo, other, "Equality matcher for type Foo") {
    return std::tie(arg.b, arg.i) == std::tie(other.b, other.i);
}

// example usage in your test
const Foo test_value {true, 42};
EXPECT_CALL(your_mock, YourMethod(EqFoo(test_value)));
