Implementing Support for Identification Properties

In the test object configuration file you defined the identification properties for your test object classes. When UFT runs a test it needs to retrieve the values for these properties. UFT uses identification property run-time values in different test object methods, such as GetROProperty. Identification property run-time values are also required for different basic capabilities, such as creating checkpoints and outputting values.

To support retrieving the run-time values of identification properties, you need to implement a JavaScript function that accepts a PropertyName parameter and returns the value of any property UFT requests. (UFT uses only lowercase letters in identification property names. If the identification property name in the test object configuration file contains uppercase letters, they are converted to lowercase.)

This function must return the property value in one of the following formats: String, Integer, Boolean, or array. When returning an array, use the toSafeArray function to convert the array to the format that UFT expects. When you provide an identification property value in an array format, UFT converts the array to a semicolon-delimited string.

For more information on writing JavaScript functions for Web Add-in Extensibility, see Designing JavaScript Functions for Your Toolkit Support Set.

UFT uses the base test object class implementation to retrieve the identification property values when the following conditions are met:

Implement your JavaScript function to return a value for the identification properties defined in the test object configuration file in the following situations:

By designing the function that returns identification property values to return a value for the logical_name property, you can control how UFT names test objects of this test object class. For more information, see Customizing the Test Object Name.

In the toolkit configuration file, you can specify the JavaScript file in which you implemented the JavaScript function that retrieves property values. You can also specify the name of the function that you implemented for this purpose (in the Control\Run\Properties element). However, if you do not specify a function name, UFT calls get_property_value (PropertyName) and this is the function that you must implement. If you do not specify a file name, UFT calls the function from the default JavaScript file you specified in the Control\Settings element (at the test object class level) or in the Controls\Settings element (at the toolkit level). For more information, see the Toolkit Configuration Schema Help.

After you create support for retrieving the run-time values of identification properties, you can test that your toolkit support set correctly enables UFT to run checkpoints on your Web elements, output property values, display the property values in the Object Spy, and run test steps with the GetROProperty operation.
