  • 《自拍教程65》Python Testlink用例导出工具xml2excel

有导入,肯定有导出,很不凑巧,只支持Xml格式的用例导出。

我们需要把Xml格式的测试用例再转换成Excel版的测试用例,以方便阅读。

准备阶段
  1. 操作Xml的模块,我建议首选ElementTree, 本次用官方自动的ElementTree即可
  2. 操作Excel的模块,一直首选openpyxl
     
Python面向对象类形式

由于本案例涉及的代码有些许难度,且相对较长,
直接以面向对象类的形式来进行建模及程序设计。

建模:先设想有这么一个空白的世界,这个世界需要哪些类型的事物(名词)。
我们需要两个类,一个是ExcelParser类用于解析Excel获取Excel数据,
一个是XMLWriter类,用于将以上获取的Excel数据写入Xml文件里去。
