实验二 JUnit测试框架的使用（2学时）
一、实验目的：
通过本次实验，掌握Junit测试框架的使用，会编写测试驱动程序，运行测试用例对Java程序测试。
二、实验内容：
需求：
NextDay是一个简单的日期计算器，计算给定日期的下一天的具体日期。如给定2020年1月1日，返回2020年1月2日；给定2020年1月31日，返回2020年2月1日。主要要求考察学生对日期边界以及异常处理的测试的能力。
要求：
使用JUnit来完成测试，需要将实验步骤截图。
实验总结
通过JUnit测试实验，我学习到了JUnit 作为一个单元测试框架，能够较快地追踪到问题的原因，减少回归错误的纠错难度。 理解了软件测试工具能够提高测试效率......
