13-Unit Testing Object-Oriented Software

一、内容

1，Object-oriented design is centered around the concepts of classes, inheritance, and messages.类、接口、方法

Classes	objects preserve state; state control is typically distributed over an entire program. State control errors are likely to occur
Inheritance	dynamic binding & complex inheritance structures are prone to faults.
Message	object-oriented programs typically have many small components and therefore more interfaces. Interface errors are more likely to occur.

二、步骤

1，列出input，output的范围 重叠的分区，但是根据规范，它们应该被视为独立的类。 2，组合test data 3，测试

三、案例

题目：

源代码

1，列出input，output的范围 重叠的分区，但是根据规范，它们应该被视为独立的类。 Overlapped partitions, but based on the specification, they should be treated as separate classes.

2，组合test data 3，测试

四、Combinational Testing

用组合测试来处理该类问题
