三个框框的EditBox

一、程序要求

　　EditBox 同时允许输入三个1到6个英文字符或数字，点击确定结束。

二、有效等价类和无效等价类划分

三、测试用例设计，根据有效和无效等价类可以设计出6个测试用例

四、程序代码：使用JavaFx实现

  1 import javafx.application.Application;
  2 import javafx.event.ActionEvent;
  3 import javafx.event.EventHandler;
  4 import javafx.scene.Scene;
  5 import javafx.scene.control.Button;
  6 import javafx.scene.control.TextField;
  7 import javafx.scene.layout.AnchorPane;
  8 import javafx.scene.text.Text;
  9 import javafx.stage.Stage;
