 In this example, we build on some of the concepts described earlier. In addition to the `compile()` method we used earlier, we now use the `createNestApplication()` method to instantiate a full Nest runtime environment. We save a reference to the running app in our `app` variable so we can use it to simulate HTTP requests.
