java.lang.AssertionError：預期：<200>卻被：<404>在球衣RESTful服務單元測試

Question

我有這個類JerseySpringSuiteTest.java：

@RunWith(Suite.class) 
@Suite.SuiteClasses({ ProductTest.class }) 
public class JerseySpringSuiteTest { 
    public static JerseyTest jerseyTest; 

    @BeforeClass 
    public static void init() { 
     jerseyTest = new JerseyTest(new WebAppDescriptor.Builder("com.product.resource") 
       .contextParam("contextConfigLocation", "classpath:applicationContext.xml").servletClass(SpringServlet.class) 
       .contextListenerClass(ContextLoaderListener.class).requestListenerClass(RequestContextListener.class).build()) { 

     }; 
    } 
} 

和ProductTest.java：

public class ProductTest{ 

    @Before 
    public void before() throws Exception { 
     JerseySpringSuiteTest.jerseyTest.setUp(); 
     ExecutorService productExecutorService = ContextLoaderListener.getCurrentWebApplicationContext().getBean(
       "productExecutorService", ExecutorService.class); 
     Assert.assertNotNull(productExecutorService); 
    } 

    @Test 
    public void testNoAction() { 
     WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource(); 
     String responseMsg = webResource.path("product/").get(String.class); 
     Assert.assertEquals("No Action Specified", responseMsg); 
    } 

    @Test 
    public void testGetProducts() throws URISyntaxException { 
     WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource().path(
       "Products/rest/product/getProducts/1/productName/01-01-2013/"); 
     ClientResponse response = webResource.accept(MediaType.APPLICATION_JSON).get(ClientResponse.class); 

     Assert.assertEquals(200, response.getStatus()); 
    } 
} 

and Product.java：

@Component 
@Path("/product") 
public class Product{ 
    @Autowired 
    private ProductService productService; 

    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    public Object noAction() { 
     return "No Action Specified"; 
    } 

    @GET 
    @Path("/getProducts/{companyID}/{companyName}/{date}") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Object getProducts(@PathParam("companyID") final int companyID, 
      @PathParam("date") final String date, @PathParam("companyName") final String companyName) 
      throws IOException { 
     return productService.getProducts(companyID, companyName, date); 
    } 
} 

當我執行它，我看到：

我能夠得到的數據在瀏覽器中，當我平安URL。

有人可以幫我獲得200和JSON對象的響應狀態嗎？

注意：我使用球衣1.17.1版和grizzly2容器。

Answer 1

根據您的noAction單元測試，正確的URL似乎是：

webResource.path("product/") 

這一點也得到實際的服務類證實：

@Path("/product") 
public class Product { 
    //... 
} 

這意味着你需要改變你的其他測試使用相同的路徑。

此外，它是companyName，而不是productName根據您的服務等級。

@Test 
public void testGetProducts() throws URISyntaxException { 

    WebResource webResource = JerseySpringSuiteTest.jerseyTest.resource(); 
    ClientResponse response = 
     webResource.path("product/getProducts/1/companyName/01-01-2013/") 
        .accept(MediaType.APPLICATION_JSON) 
        .get(ClientResponse.class); 

    Assert.assertEquals(200, response.getStatus()); 
} 

一個可能的原因是它在瀏覽器是您的服務器（Tomcat的，碼頭等）配置爲通用網址的前綴Products/rest添加到所有路徑。執行單元測試時，此服務器不在圖片中。
