Explain Test object Model, test object and run-time object ?
Test object Model is a set of object types or Classes that QuickTest uses to represents the objects in our application.
A test object class comprises of a list of properties that can individually (uniquely) identify objects of that class and a set of appropriate methods that QuickTest can record for it.
Test Object Class
A test object is an object that QuickTest creates in the test to correspond to (represent) the actual object in the application. QuickTest uses the stored information about the object during the run session to identify and check the object.
A run-time object is the real (actual) object in the application or Web site on which methods are performed during the run session.
Properties and methods of objects:
The property set for each test object is created and maintained by QuickTest. The property set for each run-time object is created and maintained by the object architect (creator) (Microsoft for Internet Explorer objects, Netscape for Netscape objects).
Similarly, methods of test objects are methods that QuickTest recognizes and records when they are executed (performed) on an object while we are recording, and that QuickTest executes when the test or component runs. Methods of Run-time object are the methods of the object in the application as defined by the object architect (creator). We can access and execute run-time object methods using the Object property.
Some important points to remember about methods and properties :
If the available test object methods or properties for an object are not sufficient or they do not provide the functionality we need, we can access the internal methods and properties of any run-time object using the Object property. We can also use the attribute object property to identify Web objects in the application according to user-defined properties.
