该函数还需要知道当前行上的文本，可以使用getline来获取存储在curr_line中的当前行。

The function also needs to know the text on the current line, which can be retrieved using getline , and is stored in curr_line.

可以将GuiTestObject只传递到构造函数中一次，然后将设置和获取文本的方法用作实例方法，而不是用作类方法。

Instead, you can pass in the GuiTestObject to the constructor once, and then use the methods to set and get the text as instance methods instead of class methods.
