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

Question

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 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.
