UFT Developer test objects

Test objects represent the UI elements in your application.

Each test object is comprised of a unique property-value set that, together with its parent object hierarchy, enables UFT Developer to identify the object in your application.

Create test object definitions with UFT Developer tools

Create test object definitions automatically using the tools that come with UFT Developer:

Object Identification Center (OIC)
  • Identifies objects in your application and captures their current property values.
  • Provides a recommended set of properties and values that are expected to uniquely identify the object.
  • Enables you to edit the recommended descriptions to fit your needs.

The OIC provides several options for using the captured or edited information to create the test objects you need.

For details, see Object Identification Center.

Application Model

A user interface provided by the UFT Developer plugin in your IDE that enables you to define and maintain a set of test objects.

You can use these test objects in multiple tests without the need to define them programmatically each time.

After you create an application model, you can use the corresponding class in your tests to access its test objects with full IntelliSense.

For details, see Application models.

When you run your test, lines of code that create test objects do not result in any communication with the UFT Developer runtime engine. The runtime engine only processes steps that use methods or properties to interact with the objects in your application. At that point, the test object is passed to the runtime engine.

If the runtime engine cannot find an object in your application that matches the description in your test object, it waits until the object appears or until the UFT Developer object synchronization timeout (default 20 seconds) elapses.

Note: You can change the object synchronization timeout in the Engine tab of the Settings dialog box. For details, see Customize UFT Developer runtime engine settings.

Create test object definitions using the SDK libraries

You can use the UFT Developer SDK libraries to manually define test objects based on the technology, object interface, and a set of properties and values that uniquely describe the object in your application. Before you learn how to code test object descriptions manually, make sure you understand the logic behind them: 

  • Each technology has its own namespace or package with the types of objects that you use for testing applications based on that technology. For example, to test Web applications use:

    C# the HP.LFT.SDK.Web namespace
    Java the com.hp.lft.sdk.web package
    JavaScript the LFT.Web package
  • Each namespace or package contains a set of interfaces that represent the types of objects you want to test in your application.

  • Each test object interface has a variety of methods and properties you can use to interact with an object in your application.

  • Each interface has a corresponding <TestObject>Description class that enables you to create a unique object definition using sets of identification properties and values. (In JavaScript, the <TestObject> classes define the description properties.)

  • The base interface for all test objects is:

    C# ITestObject
    Java TestObject


    All Description classes inherit from the interface:

    C# IDescription
    Java Description


  • Each technology namespace or package is set up as a hierarchy of objects. UFT Developer searches for objects by identifying the object that matches the test object description within its parent object.
