The first part of the function, before the `yield`, will be executed **before** the application starts.

And the part after the `yield` will be executed **after** the application has finished.

If you check, the function is decorated with an `@asynccontextmanager`.

These status codes have a name associated to recognize them, but the important part is the number.

In short:

## The normal process

The normal (default) process, is as follows.

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

As part of the application object creation, a *path operation* for `/openapi.json` (or for whatever you set your `openapi_url`) is registered.

It just returns a JSON response with the result of the application's `.openapi()` method.

     * starting at the root object contained in this value source, apply each part
     * to the object graph below this root, using either 'getXXX()' or 'isXXX()'
     * accessor types to resolve the value for each successive expression part.
     * Finally, return the result of the last expression part's resolution.</p>
