Bitmap Check Point:

Bitmap Check Point is used for verifying the area of your Web page or application as a bitmap. This check point is used for verifying static images and dynamic images as well.

Through INSERT Menu:-

1. Start Recording,
2. Choose Insert à Check Point à Bitmap Check Point, or click on Insert Check Point Button from the toolbar,

The Quick Test Window minimized and mouse pointer turns into a pointing hand

3. Click on the Object you want to verify, The Checkpoint Properties Dialogue Box opens up,

1. Select an object from the tree on which to create the bitmap checkpoint.
2.  If you want to create a bitmap checkpoint that contains multiple objects, you should select the highest level object that includes all the objects to include in the bitmap checkpoint.
3. Click OK. The Bitmap Checkpoint Properties dialog box opens. Create the Bitmap checkpoint using the options in the dialog box.

1. Set the properties you want to verify,
2. Click on OK button.

NOTE:

1.    Bitmap checkpoint is supported by all environments.

2.    Bitmap checkpoints can capture only the visible part of an object. Therefore, confirm that the object to capture is always fully visible on the screen before a bitmap checkpoint step is performed.

3.    For verifying dynamic objects, Multimedia Add-in required.

4.    We can use this Check Point for verifying Company Logos, Graphs, and Image Movements etc…

5.    In Bitmap checkpoint we can compare the exact images means the source image (in Build1) with the destination image (in build2).

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

7.    You can configure QuickTest not to save the bitmaps in the test results, or to save them even if the checkpoint passes (Tools > Options > Run > Screen Capture pane).

8.    QuickTest applies the RGB tolerance settings when comparing each pixel in the actual and expected bitmaps. The Red, Green, and Blue values for each pixel are compared separately. If any of the values differs more than the tolerance allows, the pixel fails the comparison.

9.    The pixel tolerance determines the number or percentage of pixels in the actual bitmap that can differ from those in the expected bitmap and allow the checkpoint to pass.

10.  Check entire bitmap / Check only selected area. Enables you to specify whether the checkpoint compares the entire bitmap or only a specific area of the bitmap.

11.  Save only selected area. Enables you to save only the selected area of the object with your test (to save disk space).

12.  If you select the Save only selected area check box, you can later modify the checkpoint by selecting a smaller area within the selected area, but you cannot return the bitmap to its former size.

13.  You can hold the left CTRL key to change the pointing hand to a standard pointer.  You can then change the window focus or perform operations in QuickTest or in your application, such as right-clicking, using the scroll bars, or moving the pointer over an object to display a context menu.
