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

Maybe useless as the question has been answered long time ago but here is a solution that works with any structure and which does not use MATCHER or FIELD.

Suppose we are checking: methodName(const Foo& foo):

using ::testing::_;

struct Foo {
    ...
    ...
};

EXPECT_CALL(mockObject, methodName(_))
    .WillOnce([&expectedFoo](const Foo& foo) {
        // Here, gtest macros can be used to test struct Foo's members
        // one by one for example (ASSERT_TRUE, ASSERT_EQ, ...)
        ASSERT_EQ(foo.arg1, expectedFoo.arg1);
    });
