/**
 * @def CHIP_REGISTER_TEST_SUITE(FUNCTION)
 *
 * @brief
 *   Registers a unit test suite runner
 *
 * Adds a function of the signature int(*)() to the list of test runners which
 * should be invoked when chip::RunRegisteredUnitTests() is called.
 *
 * Example:
 *
 * @code
 * int MyTestSuiteRunner()
 * {
 *     if (!RunSomeTests())
 *         return -1; // test failure
 *     return 0; // test success
 * }
 *
 * CHIP_REGISTER_TEST_SUITE(MyTestSuiteRunner)
 * @endcode
