//java图像模版匹配
//核心思路:用一张小图片,在一张大图片里去寻找,并返回该小图片所在的坐标位置,然后将鼠标移向该处,并实施相应操作。并更据页面的反馈,进行相应的判断(断言)
//1.对需要操作的对象进行截图,得到一张小图片,并保存。
//2.对当前屏幕进行截图,获得一张大图片,保存或放在内存中
//3.利用模版匹配,在大图片中,按像素对小图片进行滑动,找到小图片所在的位置。
//4.对该坐标位置(X,Y),加上小图片高度的一半(H),宽度的一般(W),得到该小图片的中心位置,即是我们要操作的坐标(X+W,Y+H)
//5。将鼠标移向该坐标(X,Y),并进行相应操作(输入,单机,双击,右键等).
//6.继续第二轮操作,第三轮操作。直到第N轮。最后进行模版匹配,来确认是否存在和预期结果一致的小图片,进而实现断言。
//由于是基于的像素匹配,所以,如果界面风格发生变化,可能出现识别不到的情况。
