I'm wondering is it ok if arguments and expects are going out of scope when they actually be matched later? like this:

struct Object
{
    // ...
};

struct TestFixture : public testing::Test
{
    MOCK_METHOD1(handle, void(Object obj));
};

TEST_F(TestFixture, Basic)
{
    {
        Object obj; // = get different obj
        EXPECT_CALL(*this, handle(obj));
    }

    {
        Object obj; // = get different obj
        EXPECT_CALL(*this, handle(obj));
    }

    {
        Object obj; // = get different obj
        EXPECT_CALL(*this, handle(obj));
    }

    // call handle 3 times
}

all the 3 obj variable will go out of scope, also will EXPECT_CALL create some kind of local variables there? Is this test ok in gtest? Thanks.

From reference/matchers.html

Except Ref(), these matchers make a copy of value in case it’s modified or destructed later.

So you are fine.
