1.使用的依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

2.使用

@SpringBootTest(classes = ShiroDemoApplication.class)  // 这里的启动类.class
public class AccountMapperTest {

    @Autowired
    private AccountMapper accountMapper;

    @Test
    public void test01(){
        List<Account> accountList = accountMapper.selectList(new QueryWrapper<Account>());
        accountList.forEach(System.out::println);
        System.out.println();
    }
}

2.普通的测试 没有spring环境

public class DesTest {

    @Test
    public void test2(){
        Integer a = 127;
        Integer b = 127;
        System.out.println(a == b);
    }


}
