MockResponse can be used to simulate a slow network. This is useful for
testing timeouts and interactive testing.

### Java
```java
MockResponse response = new MockResponse.Builder()
    .throttleBody(1024, 1, TimeUnit.SECONDS)
    .build();
```

### Kotlin
```kotlin

    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

Esse é o benefício dos padrões...

    You would only call this function yourself if you needed to override some parts,
    for example the URLs to use to load Swagger UI's JavaScript and CSS.

* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:
    * which is then used by the automatic interactive documentation user interfaces.

This might all sound abstract. Don't worry. You'll see all this in action in the [Tutorial - User Guide](tutorial/index.md).
