問題描述

我想為我的 spring boot 應用程序編寫一個功能測試，它將像從控制器到存儲庫一樣端到端運行。

對於同樣的錯誤，我嘗試按照以下解決方案進行操作，但它不起作用並且給出了相同的錯誤。

https://mkyong.com/spring-boot/spring-boot-test-unable-to-autowired-mockmvc/ https://www.yawintutor.com/error-45940-no-qualifying-bean-of-type- org-springframework-test-web-servlet-mockmvc-available/

我使用以下配置。

            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>

這也是我寫的測試類。

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebFlux;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.web.server.LocalServerPort;
import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

/*@ActiveProfiles("mock")
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, properties = "spring.main.web-application-type=reactive")
//@AutoConfigureWebTestClient
@AutoConfigureMockMvc*/

@ActiveProfiles("mock")
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "spring.main.web-application-type=reactive")
@AutoConfigureMockMvc
public class EmpWorkFeatureTest {

   /* @Autowired
    private WebApplicationContext webApplicationContext;*/

    @Autowired
    private MockMvc mockMvc;


    @Test
    void contextLoads() {
    }
    @Autowired
    private EmpController empController;

    @Autowired
    private EmpService empService;

    @Autowired
    private EmpRetriever empRetriever;



   @BeforeEach
    public void setup() {
       this.mockMvc = MockMvcBuilders.standaloneSetup(empController).build();
    }

    @Test
    public void testEmp() throws Exception {
       
        this.mockMvc.perform(get("/api/v1/work/search").param("work", "completed"))
                .andExpect(status().isOk());

    }
}

所以當我執行測試用例時出現錯誤：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.employee.EmpWorkFeatureTest': Unsatisfied dependency expressed through field 'mockMvc'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available: expected at least 1 bean which qualifies as autowire candidate.

我遇到了與 Spring Boot (2.6.7) 和 JUnit5 相同的情況。

我通過使用以下代碼直接創建 mockMvc 實例（不是自動裝配）解決了這個問題：

import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

class MyTest {

  private MockMvc mockMvc;

  @BeforeEach
  public void setUp(WebApplicationContext webApplicationContext) {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
        ... // customize to your needs
        .build();
  }
}

為了 org.springframework.test.* 可用，添加spring-test作為測試依賴。
