    interface will make your code easier to test. When you test code that makes
    HTTP requests, you can use this interface to replace the real `OkHttpClient`
    with your own mocks or fakes.

    The interface will also let you use OkHttp's API with another HTTP client's
    implementation. This is useful in sandboxed environments like Google App
    Engine.
