Test cases on a projector

I need to know what will be the test cases for testing the functionality of a projector n what do we test for in black box and white box testing for aprojector?:)

hi friend..

Not only for projector to test the functaionality whatever needed first you should understand the basic functionality

In black box:

In black box we check only the external (ie.,) if there is a button and if it is mentioned in the SRS the button should be placed at the top right of the page. we just check the button is placed top right on the particular page..

In white box:

In white box testing assume that there is a link in the form named a and by clicking the link the navigation should be done to the page b, we click on the link in the form a and then we test whether page navigation is done to the exact form (ie.,) B or not
