Robot Framework + AutoIt：字典不包含键

Question

我现在正在玩一个叫做AutoIt的库，它是用来和Robot Framework一起使用的。所以我在做一个典型的“我的第一个”Robot GUI测试，测试计算器！不幸的是，我下面的代码出现了一个错误：字典中没有键 'View Scientific'。。这个错误发生在启动计算器这个步骤中。似乎每当我调用选择计算器菜单项时，就会出现错误。

这个步骤为什么会产生错误呢？

提前谢谢你。

“字典中没有键 'View Scientific'”这个提示应该很容易理解。你试图用键 "View Scientific" 去访问一个字典，但这个字典里没有这个键。

在你的情况中，你有一个叫 ${MENUMAP} 的字典，显然它里没有键 "View Scientific"。你需要找出为什么这个字典缺少这个键。一个简单的方法是记录一下这个字典，这样你就能看到它里面有哪些键。
