作业3-单元测试

一、单元测试

1.设计思路

• 固定返回值的函数通过对比与预期结果是否一致进行测试判断

• 随机返回值的函数通过对比是否在预期结果范围内进行测试判断

• 调度场算法通过函数异常中转进行测试判断

2.部分代码

二、结构优化

1.UML类图

2.运行流程图

3.代码重构

(1)重构部分

• 题目生成
• 参数处理

(2)重构原因

• 便于单元测试
• 代码模块化
• 增加代码耦合度

(3)当前模块功能

• MathExam为主类，用于接收参数
• File为文件类，用于写出文件
• Parameter为参数处理类，用于检查接收到的参数是否合格并进行处理
• ShuntingYard为调度场算法类，用于实现调度场算法，计算表达式结果
• TaskMake为题目生成类，用于随机生成题目

三、性能调优

1.优化前效能分析

2.性能瓶颈

• String.toArray()方法处理效率较低

3.解决方案

• 使用String.charAt(index)方法替代

4.优化后效能分析

四、总结

• 同类功能的函数应该封装到同一个类中

• 多次使用的方法封装为函数，减少代码量，且代码美观
