Explain about Checking Bitmaps?..

Answer / ramyab.mca@gmail.com

Hai.....

Checking Bitmaps:

A.) 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.

When you run the test or component, QuickTest compares the
object or selected area of the object currently displayed
on the Web page or application with the bitmap stored when
the test or component was recorded. If there are
differences, QuickTest captures a bitmap of the actual
object and displays it with the expected bitmap in the
details portion of the Test Results window. By comparing
the two bitmaps (expected and actual), you can identify the
nature of the discrepancy.

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 is loaded).

Note: The results of bitmap checkpoints may be affected by
factors such as operating system, screen resolution, and
color settings.

K,Byeeee...
