同性班级

每投入,确定一个有效等价类和无效的国家.通常有三种情况来确定计划时等价班级.

如果输入规定了一系列具体的价值还是会有一个有效状态,两个国家确定为无效. 举例来说,如果一定要由120多个,有效状态是1至20,将无效状态少于1、无效状态大于20.

如果排除了一系列具体的投入价值,将有两个国家的有效、无效国家之一界定.举例来说,如果一些不可一日至二十日 不到一个国家的有效期和大于20 而1至20无效状态.

如果输入规定了布尔值,届时会有两个国家,其中一个有效、无效.

边界值分析

只考虑边界值分析边界值的投入.例如,在一些情况下被1和20之间,测试用例可一日 20、0、21.其理念是,若如预期工程计划与这些价值观 其他如预期值也会工作.

下表概述了典型的界线你想要找出.

Range

  • x[lower_bound]-1
  • x[lower_bound]
  • x[upper_bound]
  • x[upper_bound]+1

Boolean

  • True
  • False

制定测试计划

找出等价类,每一类确定边界.划定了阶级界限,写一份有效和无效的界限值,哪些行为应当预期.测试就能办好节目与边界值 并说明是什么事,当边界值测试所需的结果.

以下是一个典型的测试计划可能用来检查进入下一个时代所接受的价值观是射程在10至110.

 

等价类

有效期

无效

Between 10 and 110

> 110

 

< 10

有明确的等价类,我们现在可以设计一个试验计划,年龄.

"实际结果"栏是空白,它将于何时测试.如效果一如预期,将杨国强栏.如果没有,发生了什么评论,显示应该进入.
