mage checkpoints enable you to check the properties of a Web image. You can check an area of a Web page or application as a bitmap. While
creating a test or component, you specify the area you want to check by
selecting an object. You can check an entire object or any area within an
object. QuickTest captures the specified object as a bitmap, and inserts a
checkpoint in the test or component. You can also choose to save only the
selected area of the object with your test or component in order to save disk Space
For example, suppose you have a Web site that can display a map of a city
the user specifies. The map has control keys for zooming. You can record the
new map that is displayed after one click on the control key that zooms in
the map. Using the bitmap checkpoint, you can check that the map zooms
in correctly.
You can create bitmap checkpoints for all supported testing environments
(as long as the appropriate add-ins are loaded).
Note: The results of bitmap checkpoints may be affected by factors such as
operating system, screen resolution, and color settings.
