/**
 * The HTTP GET method requests a representation of the specified resource.
 * It is the most frequent type of request made by consumers of a typical HTTP API.
 * For this reason it's important to test every known endpoint that responds to GET requests and ensure that it
 * behaves correctly.
 *
 * Since the GET method is used to _retrieve_ data from a server, it should be implemented
 * as [safe](https://developer.mozilla.org/en-US/docs/Glossary/Safe)
 * and [idempotent](https://developer.mozilla.org/en-US/docs/Glossary/Idempotent).
 * This means that an identical request can be made once or several times in a row with the same effect while leaving
 * the server in the same state.
 *
 * ## Verify response to a GET request
 *
 * ```ts
 *  import { actorCalled } from '@serenity-js/core'
 *  import { CallAnApi, GetRequest, LastResponse, Send } from '@serenity-js/rest'
 *  import { Ensure, equals } from '@serenity-js/assertions'
 *
 *  interface Book {
 *      title: string;
 *      author: string;
 *  }
 *
 *  await actorCalled('Apisitt')
 *    .whoCan(CallAnApi.at('https://api.example.org/'))
 *    .attemptsTo(
 *      Send.a(GetRequest.to('/books/0-688-00230-7')),
 *      Ensure.that(LastResponse.status(), equals(200)),
 *      Ensure.that(LastResponse.body<Book>(), equals({
 *          title: 'Zen and the Art of Motorcycle Maintenance: An Inquiry into Values',
 *          author: 'Robert M. Pirsig',
 *      })),
 *    )
 * ```
