You are comparing pointers. The pointers are not equal.

Convert them to std::string and compare them.

    std::string sample = "Sample String";

    std::string copy = sample;
    CPPUNIT_ASSERT_EQUAL_MESSAGE("Identical strings are not equal",
                                 copy, sample);

Welcome to C++
