hello world
    pod "dummy" deleted
    ```

    As you observe, sending _world_ on a TCP connection to the server results in
    the server prepending _hello_ and echoing back with _hello world_.

1. To clean up, execute the following command:

    ```console
    $ kubectl delete -f tcp-echo.yaml
    service "tcp-echo" deleted
    deployment.apps "tcp-echo" deleted

        then:
        installation("build/install/main").exec().out == app.englishOutput

        then:
        file("build/libs/hello/shared/link/new_output/_hello.lib").assertExists()
        file("build/libs/hello/shared/runtime/new_output/_hello.dll").assertExists()
    }

    @ToBeFixedForConfigurationCache

        where:
        include             | text
        'HELLO'             | '''
            #define _HELLO(X) #X
            #define HELLO _HELLO(hello.h)
            #include HELLO

            #define _HELLO(X) #X

        '''
        'MISSING'           | '''
            #ifdef MISSING
            #include MISSING
