How to write test cases for drawing text / string in a box?

I am drawing strings in a rectangular frame. The string is drawing perfectly. Now I need to write test cases using sentesting kit. I have no ideas from where I should start. For help I have also seen the iPhone sample calculator application

But still out of sorts.

Any body having ideas 开发者_开发知识库please help.

Thanks,

GUI drawing code is often hard to test. In your case it depends how you draw your string. If you draw it into a custom view by using the -(void)drawRect: method and therein just drawing your NSString (I suppose), then I do not think your can test that this drawing happend properly. If you use a separate view like a UITextLabel you could test for its existance by using STAssertNotNil. You could also check the proper positioning by checking the view's bounds.

If you need more help, please be a bit more specific and adding clean code would help.
