Mastering Object Identification in UFT

Mastering Object Identification in UFT: Leveraging Object Spy and Advanced Inspection Techniques

Object Identification in UFT forms the backbone of successful test automation, enabling the tool to recognize and interact with application elements consistently. This comprehensive guide explores how UFT identifies objects, with a special focus on the powerful Object Spy and advanced inspection techniques that empower testers to create robust, maintainable automated tests.

Understanding Object Identification in UFT

Object Identification is the cornerstone of Unified Functional Testing's ability to interact with applications. When UFT records a test or executes a script, it must first identify each object on the application's user interface before performing any actions. This identification process relies on a set of properties that uniquely describe each object in the application.

UFT creates a Test Object Model that maps the objects in your application to corresponding test objects in UFT's object repository. Each test object has specific properties that UFT uses to recognize the corresponding object in the application during test execution. Understanding how this mapping works is crucial for creating stable tests that can withstand minor UI changes.

The object identification process follows a hierarchy, where UFT first attempts to identify an object using its mandatory properties. If those aren't sufficient, it uses additional properties from the ordinal identifier, such as the object's location on the screen or its index among similar objects. This layered approach ensures that UFT can accurately identify objects even when some properties change.

The challenge lies in ensuring that object identification remains reliable even when applications change. Poor object identification can lead to test failures, maintenance nightmares, and unreliable test results. Mastering this aspect of UFT is essential for creating stable, resilient test automation frameworks that can withstand application changes while maintaining test reliability.

Key aspects of object identification include:

• Understanding how UFT perceives objects
• Configuring identification properties
• Implementing smart identification techniques
• Handling dynamic and complex objects

• Properties used for identification can include:
• Mandatory properties (like name, html id, etc.)
• Assistive properties (additional properties to ensure unique identification)
• Ordinal identifiers (location, index, etc.)

The Object Spy: Your Gateway to Object Properties

The Object Spy is one of UFT's most valuable tools for understanding how objects are recognized. It allows testers to view the native properties and operations of any object in an open application, as well as the test object hierarchy and description properties that UFT uses to represent that object.

To use the Object Spy, you first need to open both UFT and the application you want to test. Then, click the Object Spy button on the UFT toolbar or use the shortcut Ctrl+Shift+F2. This activates the spy tool, which you can then move over any object in your application to inspect its properties.

When you hover over an object, the Object Spy displays two panes: the Properties tab shows the native properties of the object as recognized by the application, while the Methods tab lists the operations that can be performed on the object. The Object Identification section shows exactly which properties UFT is using to identify this object, which is invaluable for understanding why a test might be failing.

' Example of using Object Spy programmatically in UFT
Set objSpy = Description.Create()
objSpy("micclass").Value = "Window"
objSpy("text").Value = "Login Window"

' Spy on the login window
Set spyedObject = Desktop.ChildObjects(objSpy)(0)

' Print the properties of the spyed object
For Each prop In spyedObject.GetROProperties
    Print prop.Name & " = " & prop.Value
Next

The Object Spy also allows you to copy object properties directly to the clipboard, making it easy to add objects to the Object Repository or modify their identification properties. This feature is particularly useful when dealing with complex objects or when you need to fine-tune object identification for tricky scenarios.

Key benefits of using Object Spy include:

• Understanding object hierarchy and parent-child relationships
• Identifying the most stable properties for object identification
• Learning about available methods for object interaction
• Debugging identification issues by comparing test and runtime properties

Object Spy is particularly valuable when you encounter objects that UFT struggles to identify, as it helps you understand which properties are changing and which remain consistent across test runs.

Object Identification Center (OIC): Next-Generation Inspection

The Object Identification Center (OIC) represents a significant advancement over the traditional Object Spy. It provides a more comprehensive interface for creating unique and robust object descriptions that can withstand application changes. The OIC is particularly useful for testing modern web applications with complex dynamic content.

Unlike the basic Object Spy, which primarily focuses on viewing existing object properties, the OIC emphasizes creating and optimizing object descriptions. It provides visual feedback on how unique each property is, helping testers select the most stable and reliable properties for object identification.

The OIC also includes features for batch processing, allowing testers to analyze multiple objects simultaneously and identify common patterns or potential issues across the application. This capability is invaluable for large-scale test automation projects where consistency and reliability are paramount.

' Example of using the Object Identification Center
' First, open the OIC
OpenObjectIdentificationCenter

' Spy on multiple elements at once
elementsToSpy = Array("username_field", "password_field", "submit_button")

For Each element In elementsToSpy
    ' Spy on the element
    Spy element
    
    ' Analyze the identification properties
    AnalyzeProperties element
    
    ' Optimize the object description
    OptimizeDescription element
Next

' Save the optimized descriptions
SaveOptimizedDescriptions

When working with web applications, the OIC provides additional insights into how objects are rendered in different browsers and how their properties might change based on browser-specific behaviors. This browser-aware approach helps create tests that work consistently across different environments, reducing the likelihood of flaky tests due to browser-specific rendering issues.

Object Identification Properties: The Core of Recognition

Object Identification Properties are the attributes that UFT uses to uniquely identify objects in your application. When you record a test or use Object Spy, UFT analyzes the object and gathers a set of its attributes to create a description. These attributes typically include properties like name, ID, class, and other characteristics specific to the object type.

UFT employs two main types of properties for object identification: mandatory and optional. Mandatory properties are essential for identifying an object of a specific class, while optional properties provide additional discrimination when needed. The tool typically uses a combination of these properties to create a unique description that distinguishes one object from another.

For example, in a web application, a button might be identified by its "html tag" (mandatory), "name" (optional), and "id" (optional) properties. When UFT looks for this button during test execution, it searches for an element that matches all specified properties.

Here's a simple example of how object properties might be used in UFT script:

' Standard way to identify an object using descriptive programming
Browser("My Application").Page("Login").WebButton("name:=Submit", "html tag:=BUTTON").Click

' Using an object repository item
Browser("My Application").Page("Login").WebButton("Submit").Click

The smart identification mechanism in UFT comes into play when the primary identification properties fail. It then uses additional properties to try to identify the object, providing a fallback mechanism that can prevent test failures in certain scenarios.

Advanced Inspection Techniques for Complex Applications

While the Object Spy provides a solid foundation for understanding object identification, advanced testers often need more sophisticated techniques to handle complex applications. These techniques include using regular expressions in properties, leveraging the Smart Identification feature, and utilizing the Object Repository utilities.

Smart Identification is a powerful feature that kicks in when UFT cannot identify an object using its stored properties. Instead of immediately failing the test, Smart Identification attempts to identify the object using a set of smart algorithms that analyze the object's properties and determine the most likely match. This feature can help create more resilient tests that are less likely to break with minor UI changes.

Regular expressions can be used in object properties to handle dynamic values that change between test runs. For example, you might use a regular expression to match a user ID that includes a timestamp or a session ID that varies with each login. This technique significantly increases the flexibility and maintainability of your tests.

' Example of using regular expressions in object identification
Set objDesc = Description.Create()
objDesc("micclass").Value = "WebEdit"
objDesc("name").Value = "user_\d{4}"  ' Matches user_1234, user_5678, etc.
objDesc("html tag").Value = "INPUT"

' Find the matching object
Set matchingObjects = Browser("micclass:=Browser").Page("micclass:=Page").ChildObjects(objDesc)

Another advanced approach involves using child object properties for identification. When an object's direct properties are unstable, you can identify it through its relationship with more stable child objects. This approach leverages the object hierarchy to create more resilient identification.

For web applications, advanced techniques include:

• Using CSS selectors or XPath expressions for more precise object location
• Implementing wait methods for dynamic content that loads asynchronously
• Creating custom object classes for unique controls

Here's an example of using descriptive programming with regular expressions:

' Using regular expression for dynamic IDs
Browser("My Application").Page("Dashboard").WebEdit("regexp:=user_[0-9]+_name").Set "John Doe"

Another advanced technique is the use of the Object Repository utilities to manage and optimize object identification. These utilities allow you to export and import objects, compare repositories, and identify duplicate or redundant objects. By regularly maintaining your object repository, you can ensure that your tests remain efficient and reliable as your application evolves.

Best Practices for Object Identification

Effective object identification requires more than just knowing the tools—it requires a strategic approach to selecting properties and structuring your object repository. By following best practices, you can create tests that are both reliable and maintainable over time.

First, prioritize stable properties that are unlikely to change with application updates. Properties like IDs, names, or other uniquely identifying attributes are preferable to properties like position or text that might change frequently. When multiple properties are available, choose the ones that provide the most stable and reliable identification.

Second, organize your object repository logically. Group related objects together and use descriptive names that make it easy to understand what each object represents. This organization becomes increasingly important as your test suite grows and more objects are added to the repository.

• Key practices for robust object identification:
• Use mandatory properties whenever possible
• Minimize the number of properties used for identification
• Regularly review and optimize object descriptions
• Handle dynamic objects with specialized techniques
• Document complex object identification scenarios

Third, implement a consistent naming convention for objects in your repository. This consistency makes it easier to locate and maintain objects as your test suite evolves. Consider including the application area, page, and component in the object name to provide clear context.

Finally, regularly audit your object repository to identify potential issues such as duplicate objects, redundant properties, or objects that might be affected by application changes. This proactive maintenance helps prevent test failures and ensures the long-term stability of your automation framework.

Troubleshooting Common Object Identification Issues

Despite careful planning, object identification problems can still arise in complex applications. Understanding how to troubleshoot these issues is essential for maintaining reliable test automation. Common problems include objects not being recognized, incorrect objects being identified, or objects being identified inconsistently across different runs.

When objects aren't being recognized, the first step is to use the Object Spy or Object Identification Center to verify that the object exists and that UFT can access its properties. Check whether the object might be hidden, disabled, or created dynamically after the application loads. For dynamic objects, you may need to implement waits or synchronization points to ensure the object is ready before attempting to interact with it.

' Example of handling dynamic objects
' Wait for the dynamic element to appear
WaitProperty "Browser(""micclass:=Browser"").Page(""micclass:=Page"").WebEdit(""name:=dynamic_field"").exist", True, 10

' Alternative approach using descriptive programming for dynamic elements
Set desc = Description.Create()
desc("micclass").Value = "WebEdit"
desc("name").Value = "dynamic_field_\d+"

Set dynamicElements = Browser("micclass:=Browser").Page("micclass:=Page").ChildObjects(desc)
If dynamicElements.Count > 0 Then
    ' Interact with the first matching element
    dynamicElements(0).Set "some value"
End If

For incorrect object identification, review the properties being used and consider whether they might be ambiguous. Properties like text or position are often less reliable than unique identifiers like IDs or names. You may need to add or modify properties in the object description to improve uniqueness.

Inconsistency in object recognition can often be traced to timing issues. The application might be loading asynchronously, causing objects to appear at different times during different test runs. Implement proper synchronization techniques, such as WaitProperty statements or Exist statements, to ensure that objects are ready before attempting to interact with them.

Remember that object identification is both a science and an art. While technical knowledge is essential, experience with different applications and test scenarios will help you develop intuition for which properties are most reliable in different contexts. Regular practice and troubleshooting will make you increasingly proficient at creating robust object identification strategies.

Integrating Object Identification into Test Automation Strategy

Effective object identification should be an integral part of your overall test automation strategy, not just an afterthought. By considering object identification during test design and implementation, you can create more stable, maintainable tests that withstand application changes.

When recording tests, it's important to be mindful of which objects UFT identifies and how. Sometimes, the default identification may not be optimal for long-term test stability. By using Object Spy or OIC during recording, you can identify more stable properties or create custom identification schemes.

Maintaining a well-organized object repository is another critical aspect. Instead of relying solely on descriptive programming, consider creating logical object repositories that group related objects and use consistent identification properties. This approach makes tests easier to understand and maintain.

Key strategies for effective object identification include:

• Standardizing identification properties across similar objects
• Regularly reviewing and updating object descriptions
• Implementing version control for object repositories
• Creating documentation for complex identification schemes

By integrating these practices into your test automation workflow, you can ensure that your tests remain reliable even as applications evolve.
