Java 如何使用视图和路径变量测试Spring控制器?

Java 如何使用视图和路径变量测试Spring控制器?,java,spring,spring-mvc,junit,mockito,Java,Spring,Spring Mvc,Junit,Mockito,如何在CreditGroup中传递?还是有别的办法 控制器: @Controller @RequestMapping("/ingredients/groups") @RequiredArgsConstructor @PermissionUserWrite public class IngredientGroupController { private static final String VIEWS_PATH = "/pages/ingredient/gr

如何在CreditGroup中传递
?还是有别的办法

控制器:

@Controller
@RequestMapping("/ingredients/groups")
@RequiredArgsConstructor
@PermissionUserWrite
public class IngredientGroupController {
    private static final String VIEWS_PATH = "/pages/ingredient/group/";
    private final IngredientGroupService ingredientGroupService;

    @GetMapping("{id}")
    public String show(@PathVariable("id") IngredientGroup group, Model model) {
        if (group == null) {
            throw new ResponseStatusException(HttpStatus.NOT_FOUND, "Ingredient group not found");
        }

        model.addAttribute("group", group);
        return VIEWS_PATH + "show";
    }
}
测试:


我不知道
IngredientGroup
中的字段是什么。但是,我假设有
name
something
字段

将对象用作
@PathVariable
时,需要将其属性作为查询参数传递。因此,在您的情况下,您将要测试的url如下所示: http://localhost:8080/ingredients/groups/1?name=xxxxxx&something=otherthing


InCreditGroup
应该是什么?对于
@PathVariable
(例如long),您通常会使用基本数据类型,而不是复杂的数据类型。看一看它是实体,您是否在内存中的数据库中加载了id=1的
IngredientGroup
,以便进行测试?我想通过使用mockito来避免这种情况。但这似乎是Spring尝试使用
@PathVariable(“id”)
调用方法
findById
(JpaRepository)的唯一方法。它返回null(控制器返回状态404),因为我没有用于测试的DB。我想通过使用mockito来避免这种情况。如果您的问题得到了回答,请标记此问题已解决,并在另一个问题中添加mocking存储库。检查这个
@SpringBootTest
@AutoConfigureMockMvc
class IngredientGroupControllerTest {
    private static final String VIEWS_PATH = "/pages/ingredient/group/";
    @Autowired
    private MockMvc mockMvc;

    @Test
    @WithMockAdmin
    void show_for_admin() throws Exception {
        var ingredientGroup = Mockito.mock(IngredientGroup.class);
        mockMvc.perform(MockMvcRequestBuilders.get("/ingredients/groups/{id}", 1))
                .andExpect(status().isOk())
                .andExpect(view().name(VIEWS_PATH+"show"));
    }
}
@Test
public void show_for_admin() throws Exception {
    var ingredientGroup = Mockito.mock(IngredientGroup.class);
     mockMvc.perform(MockMvcRequestBuilders.get(String.format("/ingredients/groups/%d", 1), 
                                            ingredientGroup.getName(), 
                                            ingredientGroup.getSomething()))
                .andExpect(status().isOk());
}
