如何使用视图和路径变量测试 Spring 控制器？

Question

如何传递ingredientGroup？还是有其他方法？

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：

@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"));
    }
}

我不知道IngredientGroup 中的字段是什么。但是，我认为有字段name 和something。

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

@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());
}
