测试web API服务

我想测试给定Web API服务的方法。我可以通过添加一个测试项目、实例化控制器和测试方法来实现这一点。然而，我不想只测试方法，我想测试请求和响应。我在Java中做了类似的事情，像这样:

  private HttpServer server;
    @Before
    public void before() {
        this.server = Servidor.initializeServer();
    }
    @After
    public void stopServer() {
        server.stop();
    }
    @Test
    public void testaQueBuscarUmCarrinhoTrazOCarrinhoEsperado() {
        Client client = ClientBuilder.newClient();
        WebTarget target = client.target("http://localhost:8080");
        String conteudo = target.path("/carrinhos").request().get(String.class);
        Carrinho carrinho = (Carrinho) new XStream().fromXML(conteudo);
        Assert.assertEquals("Rua Teste", carrinho.getRua());
    }
