【Web自动化测试——代码篇十二】自动化测试模型——数据驱动测试和关键字驱动测试...

自动化测试模型可以看作自动化测试框架与工具设计的思想。随着自动化测试技术的发展,演化为以下几种模型:

  • 线性测试
  • 模块化驱动侧式
  • 数据驱动测试
  • 关键字驱动测试

数据驱动测试

前一篇所讲的模块化驱动测试能够很好的解决脚本重复的问题,但是在针对同一个功能进行不同数据的测试,从而检测测试结果的变化时仍然需要重复地编写测试脚本。于是,数据驱动测试的概念就为解决这类问题而被提出。
我们可以通过读取定义的数组、字典,或者是外部文件(excel、csv、txt、xml等),都可以看作是数据驱动,从而实现数据与脚本的分离,进一步增强脚本的复用性。

读取txt文件

【Web自动化测试——代码篇十二】自动化测试模型——数据驱动测试和关键字驱动测试..._第2张图片

Java

(ノへ ̄、)这段代码存在一个问题,txt文件中有四组数据,但运行时只执行了三组数据(运行时忽略了一条密码为空的数据)。

读取excel文件

Excel文件数据必须时文本格式

Java

进入http://poi.apache.org/download.html下载POI的Jar包
问题一:
【Web自动化测试——代码篇十二】自动化测试模型——数据驱动测试和关键字驱动测试..._第3张图片
解决方法:
进入http://mvnrepository.com/artifact/org.apache.xmlbeans/xmlbeans/2.6.0,下载jar包

问题二:
【Web自动化测试——代码篇十二】自动化测试模型——数据驱动测试和关键字驱动测试..._第4张图片
解决方法:
进入http://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.1,下载jar包

问题三:
在遇到Excel单元值为空时sheet.getRow(i).getCell(j).getStringCellValue()会报错
解决方法:
在Excel中把空值改为空格,然后在代码中获取该值后去空格。

浅谈关键字驱动测试

       在数据驱动的基础上,我们把“数据”转化为“关键字”后,通过关键字的改变从而引起测试结果的变化。
       为何我要在这里说明是“浅谈”呢?在关键字驱动测试中,我们可以将测试的对象、满足条件、传输值、断言等,甚至是所需要读取的外部文件以及外部类库,所有的相关条件存储在文件中(典型的关键字驱动工具:UFT)。我们可以将关键字以“填表格”形式写入文件中,从而降低脚本的编写难度。
       正因如此,采用关键字驱动测试来编写同样的脚本需要较高的学习成本。同样,这样的框架越到后期越难维护,可靠性也会变差。所以,暂时不深入研究关键字驱动测试。
