Micronaut:无法测试junit的重定向响应

问题描述 投票:2回答:2

我正在尝试测试Controller返回HttpResponse.seeOther(URI.create(redirectUri));的重定向方案。问题是我的测试用例遵循重定向而不是返回HttpResponse<String>或类似的东西。如何在Micronaut中进行测试?

Controller

  @Post("/some/endpoint")
  public HttpResponse<?> capture(@Body Map<String, String> body)
      throws Exception {
    // do something
    String uri = getRedirectUri();
    return HttpResponse.seeOther(URI.create(redirectUri));
  }

Test

  @Test
  public void testCapture() {
    String expectedUri = getRedirectUri();
    //following doesn't work
    String redirectUrl = client.toBlocking().retrieve(HttpRequest.POST("/some/endpoint",  body), String.class);
    assertEquals(expectedUri, redirectUrl);

    //following also doesn't work
    HttpResponse<String> response = client.toBlocking().retrieve(HttpRequest.POST("/some/controller", someBody), HttpResponse.class);
    assertEquals(HttpStatus.SEE_OTHER, response.status());
  }

错误

我测试了某些方案,并观察到Micronaut客户端处理了某些类型的Response(Http请参见其他,错误的请求,服务器错误)。在您的情况下,一种解决方法是尝试获取对象,该对象由See Other指向并对其进行assert的端点给出。

但是如果真的只想获取String,则在Controller方法中,将返回值更改为HttpResponse.status(HttpStatus.SEE_OTHER).body(URI.create(redirectUri);

通过使用client.exchange()方法实施替代方法,该方法返回发布者。 io.reactivex.subscribers.TestSubscriber可用于订阅和测试断言。

[HttpClient.exchange()方法签名-

<I, O> Publisher<HttpResponse<O>> exchange(HttpRequest<I> request, Class<O> bodyType) {...}

使用TestSubscriber-]的有效测试用例

@Test
public void testCapture() {
  //Instead of following client.toBlocking().retrieve()
  /*
  String redirectUrl = client.toBlocking()
      .retrieve(HttpRequest.POST("/some/endpoint",  body), String.class);
  */

  // Use client.exchange()
  Publisher<HttpResponse<Object>> exchange =
    client.exchange(HttpRequest.POST("/payment/1234567890/capture", body)
        .contentType(MediaType.APPLICATION_FORM_URLENCODED), Object.class);

  TestSubscriber<HttpResponse<?>> testSubscriber = new TestSubscriber<HttpResponse<?>>() {
    @Override
    public void onNext(HttpResponse<?> httpResponse) {
      assertNotNull(httpResponse);
      assertEquals(HttpStatus.SEE_OTHER, httpResponse.status());
      assertEquals(getRedirectUri(), httpResponse.header("location"));
    }
  };

  exchange.subscribe(testSubscriber);

  // await to allow for response
  testSubscriber.awaitTerminalEvent(2, TimeUnit.SECONDS);

  // assert for errors, completion, terminated etc.
  testSubscriber.assertNoErrors();
  testSubscriber.assertComplete();
  testSubscriber.assertTerminated();
}
