The Normal Recording Mode

The normal recording mode is the default recordingmode.

In this mode, QuickTest:

Records a step for each interaction with an object.

Learns the properties of an object and stores them in the objectrepository for object identification at run time.

The Low-level Recording Mode

The low-level recording mode enables you to record onany object in the application, regardless of whetherQuickTest recognizes the object.

In low-level recording, QuickTest:

learns the object properties of run-time objects in the Windowclass or the WinObject class.

records the exact coordinates of mouse clicks, drag-and-dropmovements, and type operations on an object.

records a step for each interaction with an object.

A Bitmap Checkpoint

A bitmap checkpoint checks an area of an application asa bitmap.

You use a bitmap checkpoint to compare an expectedimage to the actual image at run time, pixel by pixel.

Bitmap checkpoints are sensitive to changes in imageproperties, image size, and screen resolution.
