Bitmap Image Recording
I've read that bitmap image recording is not an efficient method of test automation because the images are large, you can't change your display settings and they are burdensome to maintain. I would like to know the experiences anyone has had using WinRunner's bitmap recording. I'm considering using this as part of a SmokeTest for my company's application using a test machine designated for this purpose, but I'm concerned that it may not be a good return on investment. Your feedback is greatly appreciated.
Re: Bitmap Image Recording
A friend of mine uses Bitmap Image approach extensively.
His test suite takes 29 Hours to run!
He is testing an application that generates reports and finds this method works good and can't test the Report Output any other way.
That being said, the Bitmap Image should only be used as a last resort when No other method will produce the results you want.
A GUI checkpoint is a much better choice.
It will check any or all of the properties of the window or object.
The problem is Not that the images are large, but the Bitmap Image may match and a property of the Window or Object may Not be correct.
Also if the Font or other property of the Window or Object changes (by design) you need to recapture all of the Bitmap Images again. A time consuming task.
Plus your Not sure the Images you're capturing are correct! You need to visually check every Window or Object to make sure it is correct.
Almost None of the tests I create use the Bitmap Image approach.
