连接拒绝,放心的junit测试用例

Har*_*ana 14 java rest junit rest-assured

下面的测试用例给了我一个连接拒绝异常,当我评论方法体时,它是成功的.所以我相信端口没有问题,但我确定无法确定调用的问题.即使我与其他客户端一起检查,它也能成功地将书籍作为json返回.

@Test
public void testMe() {      
    get("/book").then().assertThat().contentType(ContentType.JSON);
}

控制器如下所示,

@RestController
@RequestMapping("/book")
public class BookController {
//Other crud api's are there

   @RequestMapping(method = RequestMethod.GET)
   public Map<String, Object> getAllBooks(){
   List<Book> books = bookRepository.findAll();
   Map<String, Object> response = new LinkedHashMap<String, Object>();
   response.put("totalBooks", books.size());
   response.put("books", books);
   return response;
   }

通常我的应用程序在端口8080上运行,但在测试中它似乎在不同的端口上运行(即使我没有改变任何关于端口的东西).

对我来说,以下解决了这个问题:

将其添加到SpringBootTest:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
Run Code Online (Sandbox Code Playgroud)

获取指定的端口(没有随机端口设置时无效):

@LocalServerPort
private int port;
Run Code Online (Sandbox Code Playgroud)

使用新端口设置为预先确认的测试添加前缀:

given().port(port).when().get...

要么

    RestAssured.port = port;
}

REST Assured 执行真正的 http 请求，看起来服务器没有运行（或者它在与 8080 不同的端口上运行，这是 REST Assured 使用的默认端口）。如果您不想发出真正的 http 请求，您可以查看Spring MockMvc 模块，它可以说更容易设置。
