1. pom.xml

• Eclipse创建时需要手动加依赖坐标

<!- 添加 junit 环境的 jar 包 ->
<depndency>
    <groupId>org.springframework.bot</groupId>
    <artifactId>spring-bot-starter-test</artifactId>
</depndency>

• IDEA创建SpringBoot项目会自动导入

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <scope>test</scope>
</dependency>

2. 生成测试文件

快捷键：Ctrl+Shift+T
@RunWith:启动器
SpringJUnit4ClasRuner.clas：让 junit 与 spring 环境进行整合
@SpringBotTest(clases={Ap.clas}) 1,当前类为 springBot 的测试类
@SpringBotTest(clases={Ap.clas}) 2,加载 SpringBot 启动类。启动springBot
@Contextconfiguartion("claspath:aplicationContext.xml") junit 与 spring 整合

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = {SpringBootTestApplication.class})
public class UserServiceImplTest {

    @Autowired
    private UserServiceImpl userService;

    @Test
    public void addUser() {
        userService.addUser();
    }
}
