RegisterUserFunc Statement

Abstract

The RegisterUserFunc statement is used to register the previously registered function or method. This method could have been used for some special requirement. The statement in itself falls under the category of utility statements and not utility objects.

Remember there is a difference between utility statements and utility objects.

Before we dig down deep into the usage let’s quickly visit some general questions.

In the interview usually, you might be questioned in different ways like:

1. How to set custom method for any control class?
2. Can you use the RegisterUserFunc statement by calling some other methods in external function file?
3. What are the objects and parameters of RegisterUserFunc statement?
4. Is RegisterUserFunc an object or statement?
   

Discussion

This is the most used and discussed statement in QTP. The RegisterUserFunc statement instructs enables you to add new custom methods to test object classes or change the behavior of an existing test object method during a run session.

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

If the specified custom method name does not already exist for the test object class, it becomes a new method for the test object class.

Point to Note here:

1. If you register a function within a reusable action, it is recommended that you de-register the method at the end of the action.
2. You cannot register a method for a QuickTest reserved object (such as Recover, Reporter, and the other objects listed in the Utility Objects.
3. The custom method name cannot contain spaces.
4. The function can be located in your action or in any library file associated with your test or component.
5. 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).
6. If the custom method name is a defined QTP method for the test object class, your definition (temporarily) overrides the existing functionality of the specified method.

Syntax

RegisterUserFunc TOClass, MethodName, FunctionName, SetAsDefault

Let’s see the parameters and their usage description for this statement:

Example

Suppose that the Web page contained a Country edit box, and by default, the box contained the value USA. The following example registers the Set method to use the MyCustomSet function in order to report the default value of the edit box to the run results before the new value is entered. After using the registered method in a WebEdit.Set statement for the Country edit box, the UnRegisterUserFunc method is used to return the Set method to the standard QuickTest functionality.

'RegisterUserFunc  example

Function MyCustomSet (obj, x)

	dim y

	y = obj.GetROProperty("value")

	Reporter.ReportEvent micDone, "previous value", y

	MyCustomSet=obj.Set(x)

End Function

RegisterUserFunc "WebEdit", "Set", "MyCustomSet"

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

UnRegisterUserFunc "WebEdit", "Set"
