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.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 website http://www.onestoptesting.com/qtp/test-model-object.asp# - - - 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 :
- Each test object method we execute (perform) while
recording is recorded as a separate step in the test. When we run the
test, QuickTest executes (performs) the recorded test object method on
the run-time object.
- Properties of test object are captured from object
while recording. QuickTest uses the values of these properties to
identify runtime objects in the application during a run session.
- Property values of objects in the application may
change .To make the test object property values match the property
values of the run-time object, we can modify test object properties
manually while designing the test or component or using SetTOProperty
statements during a run session. We can also use regular expressions to
identify property values.
- We can view or modify the test object property values
that are stored with the test or component in the Object Properties or
Object Repository dialog box.
- We can view the syntax of the test object methods as well as the run-time methods of any object on our dekstop http://www.onestoptesting.com/qtp/test-model-object.asp# - - using the Methods tab of the Object Spy.
- We can retrieve or modify property values of the TEST
OBJECT during the run session by adding GetTOProperty and SetTOProperty
statements in the Keyword View or Expert View. We can retrieve property
values of the RUNTIME OBJECT during the run session by adding
GetROProperty statements.
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.
