我正在创建一个基本的应用程序，并希望在注册过程中添加一个用户到数据库。我创建了一个用户类，用户存储库类和UserService类。我试图测试这些类。下面是代码。

import static org.assertj.core.api.Assertions.assertThat;

import org.example.User;
import org.example.UserRepository;
import org.example.UserService;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertNotNull;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;

@RunWith(SpringRunner.class)
@DataJpaTest
public class UserTest {

    @Test
    public void testCreateUser() {

    }
}

字符串
我有例外

我尝试添加注解@SpringBootTest，仍然得到同样的错误。我也尝试添加ContextConfiguration，它也不起作用。我正在尝试@RunWith。你能给给予任何建议吗？

junit

这是因为您混合使用JUnit 4（org.junit）来执行测试，使用JUnit 5（org.junit.jupiter）来编写测试。
我建议从类路径中删除JUnit 4（依赖项junit:junit），只使用JUnit 5（依赖项org.junit.junit-jupiter:junit-jupiter）。
如果您想使用旧的JUnit 4，请将导入从import org.junit.jupiter.api.Test;更改为import org.junit.Test;，以便JUnit可以找到测试方法。
