RegisterUserFunc Statement in QTP

RegisterUserFunc in QTP automation testing : Enables you to add new methods to test objects or change the behavior of an existing test object method during a run session.

When you use this statement, QuickTest uses your user-defined function as a method of a specified test object class for the remainder of a run session, or until you unregister the method.

If the specified method name does not already exist for the test object, it becomes a new method for the object. If the method name is a defined QuickTest method for the object, your definition (temporarily) overrides the existing functionality of the specified method. 


Notes:

A registered method applies only to the test or library file in which you register it (or to any tests calling an action containing a RegisterUserFunc statement).

For tests, if you register a function within a reusable action, it is recommended that you unregister the method at the end of the action. 


QuickTest clears all function registrations at the beginning of each run session.

For more information on registering user-defined functions, see the HP QuickTest Professional User Guide.

Syntax

RegisterUserFunc TOClass, MethodName, FunctionName, SetAsDefault



Argument

Type

Description

TOClass

String

The test object class for which you want to register the method.

MethodName

String

The method you want to register.

FunctionName

String

The name of your user-defined function. The function can be located in your action or in any library file associated with your test or component.

SetAsDefault

Boolean

Optional. Indicates whether the registered function is used as the default operation for the test object.

Default = False

Note: When you select a test object in the Keyword View or Step Generator, the default operation is automatically displayed in the Operation column (Keyword View) or Operation box (Step Generator). For more information, see the HP QuickTest Professional User Guide.

Examples

The following example uses the RegisterUserFunc method to create a new Copy method for the WinEdit test object that copies all the text in an edit box to the Windows Clipboard.

Sub Copy (edit)

       Edit.Click 3, 3

       Edit.SetSelection 0, Len(Edit.GetROProperty("text"))

       Edit.Type micCtrlDwn + "c" + micCtrlUp

End Sub

RegisterUserFunc "WinEdit", "Copy", "Copy"

' Now you can call the new method
Dialog("Login").WinEdit("Agent Name:").Copy

The following example uses the RegisterUserFunc method to modify the behavior of the WebEdit.Set method as defined in the MySet function. The new behavior enables the Set method to retrieve and report the default value of the edit box before the new value is entered.

Function MySet (obj, x)

dim y

y = obj.GetROProperty("value")

Reporter.ReportEvent micDone, "previous value", y

MySet=obj.Set(x)

End Function

RegisterUserFunc "WebEdit", "Set", "MySet"

Browser("MercuryTours").Page("FindFlights").WebEdit("Country").Set "Canada"

UnRegisterUserFunc "WebEdit", "Set"
