    Base class for testing eRPC with different languages.

    Define this abstract functions:
        - client(): This function should start the eRPC client with test cases
        - test(): This function should start the eRPC server
        - test_case_server_exist(), test_case_client_exist(): Return if client/server implementation in given language exists
        - init_tests(): Init anything that concreate class need to run tests (build, flash, download, ...)

        - Init client and server with all arguments
        - Iter through client's test_cases
            - call init_test(test_case, test_suit_name, transport) on client and server
            - Check if test case exist for client/server
            - call server() on given implementation
