Rational Functional Tester (RFT) 是一款集成在Eclipse上的自动化测试工具。而自动化测试最麻烦的维护部分，一大部分也是指的是对象库文件的管理维护。
之前的项目里，经常遇到对象库文件有冲突，虽然我们有用Rational Team Concert (RTC) 去做compair & merge 的工作，但是还是不是太理想，有时候还是会遇到一些文件的冲突（主要是对象文件，“*.rftdef”文件，以及与之相关的helper文件）。下图就是一个典型的rftdef文件，很容易看出其本质就是个xml文件
而冲突的内容主要就是<TestObject>元素的冲突。其实就是两个XML文件的合并。
我用python写了个RftDef类去将不同的<TestObject>元素加在最后

上面的代码会比较两个rftdef文件 test1 和 test2，最后生成的是out.rftdef文件
附test1.rftdef文件，test2则是自己随便改了些<TestObject> Name里面的内容
