java - SpringRunner.class 无法解析为类型
问题描述
这是我测试我的项目的测试代码。我有所有的进口，但它似乎仍然无法找到SpringRunner.class. 下面是我的课。
package c03xxx.test;
import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.jupiter.api.Assertions.*;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.content;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultMatcher;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.ContextConfiguration;
import CO3102.hw2.domain.AccountTypes;
import CO3102.hw2.domain.User;
import CO3102.hw2.repositories.UserRepository;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class ApplicationTest {
@Autowired
private MockMvc mockMvc;
@Test
public void testSignUp() throws Exception{
User u = new User();
u.setDob("31/12/1999");
u.setEmail("testEmail@le.ac.uk");
u.setFav_team("Liverpool");
u.setNumber_of_friends(0);
u.setPassword("123456");
u.setUsername("TESTUSERNAME");
this.mockMvc.perform(get("/newUser"))
.andExpect(status().isCreated());
}
}
这是我收到的错误消息：

有什么原因可能无法正常工作。在出现此错误之前，我有一个 mockMvc 错误，已通过添加修复，SpringRunner.class但现在这也不起作用！如果有人可以提供帮助，将不胜感激。
解决方案
你有jupiter，即JUnit5。但是从 JUnit4 导入SpringRunner。实际上整个字符串：
@RunWith(SpringRunner.class)
使用 JUnit5 运行时不需要
