java - 重定向 URL 应为 : but was in Junit

Question

我有以下类(class):

商店.java

@Controller
public class Store {

    @Autowired
    private List<Products> products;

    @GetMapping(value = "cart/busket")
    public String busket() {
        return "redirect:/cart/index";
    }

    @GetMapping(value = "/")
    public String index(final ModelMap model) {

        model.addAttribute("products", this.products);
        return "product/index";
    }

    @GetMapping(value = "cart/buy/{id}")
    public String buy(@PathVariable("id") final String id, final HttpSession session) {

        //some logic

        return "redirect:/";
  }
//and other methods
}

Main.java - 运行应用程序

@SpringBootApplication
@Configuration
@ImportResource("classpath*:beans.xml")
public class MainApp {
    public static void main(final String[] args) {

        SpringApplication.run(MainApp.class, args);

    }
}

StoreTest.java - 我的测试类

@SpringBootTest
@ContextConfiguration(classes = Store.class, locations = {"classpath*:beans.xml"})
@RunWith(SpringRunner.class)
public class StoreTest {

    @InjectMocks
    private Store   myController;
    private List<Products> products;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        // Process mock annotations
        MockitoAnnotations.initMocks(this);

        // Setup Spring test in standalone mode
        this.mockMvc = MockMvcBuilders.standaloneSetup(this.myController).build();

    }

    @Test
    public void testBusket_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/cart/busket"))
                .andExpect(MockMvcResultMatchers.redirectedUrl("/cart/index"));
    }

    @Test
    public void testBuy_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("cart/buy/1"))
                .andExpect(MockMvcResultMatchers.redirectedUrl("/"));
    }

    @Test
    public void testIndex_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/"))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }

}

我的 testBuy_StatusOK() 不起作用。它说:重定向的 URL 预期:“/”，但为“null”。我认为这是因为我的依赖项没有实现。我尝试了各种方法，但不起作用:\

更新了 StoreTest.java

@WebMvcTest(Store.class)
@ContextConfiguration(classes = Store.class, locations = {"classpath*:beans.xml"})
@RunWith(SpringRunner.class)
public class StoreTest {

    @MockBean
    private List<Products> products;

    @Autowired
    private MockMvc        mockMvc;

    @Before
    public void setup() {
        // Process mock annotations
        MockitoAnnotations.initMocks(this);

        // Setup Spring test in standalone mode
        this.mockMvc = MockMvcBuilders.standaloneSetup(this).build();

    }

    @Test
    public void testBusket_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/cart/busket"))
                .andExpect(MockMvcResultMatchers.redirectedUrl("/cart/index"));
    }

    @Test
    public void testBuy_StatusOK() throws Exception {

        this.mockMvc.perform(MockMvcRequestBuilders.get("cart/buy/1"))
                .andExpect(MockMvcResultMatchers.redirectedUrl("/"));
    }

    @Test
    public void testGetProducts_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/"))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }

    @Test
    public void testIndex_StatusOK() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/"))
                .andExpect(MockMvcResultMatchers.status().isOk());
    }

}

Beans.xml - 包含 beans 的文件

<beans>

...


<bean id="product1"
    class="...entities.Products">
    <constructor-arg name="name" value="Cherry" />
    <constructor-arg name="description" value="This is very good cherry" />
    <constructor-arg name="price" value="500" />
    <constructor-arg name="id" value="1" />
  </bean>

  <bean id="product2"
    class="...entities.Products">
    <constructor-arg name="name" value="Cucumber" />
    <constructor-arg name="description" value="This is an amazing cucumber" />
    <constructor-arg name="price" value="1000" />
    <constructor-arg name="id" value="2" />
  </bean>

  <bean id="product3"
    class="...entities.Products">
    <constructor-arg name="name" value="Apple" />
    <constructor-arg name="description" value="This is pretty good apple" />
    <constructor-arg name="price" value="3000" />
    <constructor-arg name="id" value="3" />
  </bean>

  <util:list id="products" value-type="...entities.Products"> <ref bean="product1" /> <ref bean="product2" /> <ref bean="product3" /> </util:list>

</beans>

Answer 1

问题是 MockMvc 完全忽略测试中的 myController 变量，并使用它创建的 Controller 。

修复:

• 从测试中删除 private Store myController;
• 要覆盖 Controller 的任何依赖项，请使用@MockBean

此外，如果您打算仅测试应用程序的网络切片

• 将@SpringBootTest更改为@WebMvcTest(Store.class)
• 使用注入(inject)的MockMvc @Autowired private MockMvc mockMvc;

更新

如果您想在使用 @WebMvcTest 时注入(inject) @Bean，您可以在测试中提供它:

@Configuration
class ProductConfig {
    @Bean
    public List<Product> getProducts() {
        return List.of(new Product());
    }
}

@WebMvcTest(value = Store.class)
@Import({ProductConfig.class})
public class StoreTest {
}

更新2

如果你想从xml文件中读取bean，你可以使用:

@Configuration
@ImportResource({"classpath:beans.xml"})
class ProductConfig {
}

@WebMvcTest(value = Store.class)
@Import({ProductConfig.class})
public class StoreTest {
}
