    模拟实现一个基于文本界面的《开发团队调度软件》

    该软件主要实现以下功能：

    • 软件启动时，根据给定的数据创建公司员工部分成员列表（数组）
    • 根据菜单提示，基于现有的公司成员，组建一个开发团队以开发一个新的项目
    • 组建过程中包括将成员插入到团队中，或从团队中删除某成员，还可以列出团队成员中现有的成员列表
    • 开发团队包括架构师、设计师和程序员

    TeamException类

    测试NameListService类的getAllEmployees()

    测试结果如下：

    测试NameListService类的getEmployees()

    1. package com.light.team.junit;
