登录业务

@Service
public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper, Employee> implements EmployeeService {

    @Resource
    private JwtUtils jwtUtils;
    @Override
    public String login(Employee employee) {
        //2.构造条件
        LambdaQueryWrapper<Employee> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(Employee::getUsername,employee.getUsername())
                .or()
                .eq(Employee::getPhone,employee.getPhone());
        //1. 根据用户名或者密码查询用户信息
        Employee employeeInDb = this.getOne(wrapper);

        //3.判断是否查询到用户
        if(employeeInDb == null){
            throw new BusinessException(ResponseEnum.USER_INVALID);
        }

        //4.比较密码
        if(!BCrypt.checkpw(employee.getPassword(),employeeInDb.getPassword())){
            throw new BusinessException(ResponseEnum.PASSWORD_INVALID);
        }
        //5.签发token

        String token = jwtUtils.createJwt(
                employeeInDb.getId(),
                null,
                60*60*24*7L,
                "1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890"
        );
        return token;
    }
}

现要对这个登录业务进行测试，要测试的情况有 登录成功，账号或电话输入错误，密码输入错误三种情况

异常状态码

单元测试

通过断言对失败的情况进行判定，通过Assertions.assertEquals进行进一步判定异常的具体出错信息。

@SpringBootTest
public class EmployeeControllerTests {
    @Resource
    private EmployeeController employeeController;

    @Test
    //成功的情况
    public void testLoginSuccess() {
        Employee employee = new Employee();
        employee.setUsername("admin");
        employee.setPassword("123456");
    }

    @Test
    public void testLoginPasswordError() {
        //断言
        BusinessException e = Assertions.assertThrows(BusinessException.class, () -> {
            Employee employee = new Employee();
            employee.setUsername("admin");
            employee.setPassword("1234567");
            employeeController.login(employee);
        });
        //进一步断定更详细的异常类型
        Assertions.assertEquals("密码错误",e.getResponse().getMessage());
    }

    @Test
    public void testLoginUsernameError() {
        BusinessException e = Assertions.assertThrows(BusinessException.class, () -> {
            Employee employee = new Employee();
            employee.setUsername("adminaa");
            employee.setPassword("123456");
            employeeController.login(employee);
        });
        Assertions.assertEquals("用户不存在",e.getResponse().getMessage());
    }

}

测试结果
