我的單元測試用例在 spring 引導中的 PUT api controller 失敗

[英]my unit test case is failing for the PUT api controller in spring boot

 原文  2020-12-29 03:22:50  6   1    java/ spring-boot

問題描述

我創建了一個基本的 CRUD api。我已經為所有 api 編寫了測試用例，每個測試用例都可以正常工作，但不能 PUT。 它總是給我找不到資源錯誤。

model

package com.example.crudrestapi.model;


import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Data
@Entity
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Customer {

    @Id
    @GeneratedValue private Long id;
    private String name;
    private String address;
    private String phoneNumber;
    private String gstin;
    private float outstandingBalance;
}

測試

@ExtendWith(SpringExtension.class)
@WebMvcTest(CrudController.class)
class CrudControllerTest {

    @Autowired
    MockMvc mockMvc;

    @MockBean
    CustomerRepo customerRepo;
    
    @Test
    void putApiTest() throws Exception {

        Customer customer = Customer.builder().build();
        given(customerRepo.findById(Long.parseLong("1"))).willReturn(Optional.of(customer));

        mockMvc.perform(put("/customers/{customerId}", 1)
                .content("{ \"name\" : \"test\", \"address\" : \"test\" }")
                .contentType(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk());
    }

controller

@PutMapping("customers/{customerId}")
    public Customer updateCustomer(@RequestBody Customer newCustomer, @PathVariable Long customerId) throws ResourceNotFoundException {

        return customerRepo.findById(customerId)
                .map(customer -> {
                    if (newCustomer.getName() != null)
                        customer.setName(newCustomer.getName());
                    if (newCustomer.getGstin() != null)
                        customer.setGstin(newCustomer.getGstin());
                    if (newCustomer.getPhoneNumber() != null)
                        customer.setPhoneNumber(newCustomer.getPhoneNumber());
                    if (newCustomer.getAddress() != null)
                        customer.setAddress(newCustomer.getAddress());
                    if (newCustomer.getOutstandingBalance() != 0.0f)
                        customer.setOutstandingBalance(newCustomer.getOutstandingBalance());
                    return customerRepo.save(customer);
                }).orElseThrow( () ->new ResourceNotFoundException());

    }

我得到的錯誤

我不明白為什么我得到404 。Object 不是由構建器創建的..??

我應該在構建器中指定id嗎？？

您還需要在存儲庫上模擬“保存”方法。 從 Optional.map 方法返回 null 將返回一個空的 Optional，這將導致 orElseThrows 執行其供應商。

請參閱 Optional.map javadoc 。
