How QTP Learns Objects?First, it "looks" at the object being learned and stores it as a test object,
determining in which test object class it fits.QuickTest might classify the test object as a standard
Windows dialog box (Dialog), a Web button (WebButton), or a Visual Basic
scroll bar object (VbScrollBar), for example.
Then, QuickTest "considers" identification properties for the test object. For
each test object class, QuickTest has a list of mandatory properties that it
always learns;
When QuickTest learns an object, it always learns
these default property values, and then "looks" at the rest of the objects on the page, dialog box, or other parent object to check whether this
description is enough to uniquely identify the object. If it is not, QuickTest adds assistive properties, one by one, to the description, until it has
compiled a unique description;
If no assistive properties are available, or if those available are not sufficient to create a unique description, QuickTest
adds a special ordinal identifier, such as the object’s location on the page or
in the source code, to create a unique descriptionHow QuickTest Identifies Objects During the Run Session ?QuickTest searches for a run-time object that exactly matches the description of the test object it learned previously. It expects to find a perfect match for both the mandatory and any assistive properties it used to create a unique description while learning the object. As long as the object in the application does not change significantly, the description learned is almost always sufficient for QuickTest to uniquely identify the object. This is true for most objects, but your application could include objects that are more difficult to identify during subsequent run sessions.
QuickTest uses process of elimination with its Smart Identification mechanism to identify an object, even when the learned description is no longer accurate. Even if the values of your identification
properties change, QuickTest maintains your test’s reusability by identifying the object using Smart Identification.
