Mastering UFT Object Identification for Accessibility

Mastering Object Identification in UFT: Understanding Accessibility Objects and ARIA Properties

Unified Functional Testing (UFT) is a powerful automation tool that enables testers to create robust test scripts for various applications. One of the critical aspects of UFT is its object identification mechanism, which allows the tool to recognize and interact with different elements in the application under test. This capability becomes even more crucial when dealing with accessibility objects and ARIA (Accessible Rich Internet Applications) properties, which are essential for ensuring applications are usable by people with disabilities.

Understanding Object Identification in UFT

Object identification is the foundation of any automation testing process in UFT. When UFT records or executes a test, it needs to identify objects in the application to perform actions on them. The tool uses a combination of properties to uniquely identify each object in the application. These properties are stored in the Object Repository, which acts as a centralized location for managing test objects.

UFT follows a systematic approach to identify objects. First, it attempts to identify the object using the mandatory properties specified in the Object Identification settings. If an object cannot be uniquely identified with mandatory properties alone, UFT uses assistive properties to further distinguish the object. In cases where multiple objects match the specified properties, UFT employs ordinal identifiers such as location, index, or creation time to identify the correct object.

• The object identification process in UFT involves several steps:
• Collecting available properties from the object
• Comparing these properties with those in the Object Repository
• Selecting the best match based on the identification mechanism settings
• Handling potential identification failures with smart identification features

Understanding how UFT identifies objects is crucial for creating reliable and maintainable test scripts, especially when dealing with complex applications that include accessibility elements.

The Role of Accessibility in Modern Applications

Accessibility has become a critical aspect of modern software development. With an increasing number of users relying on assistive technologies to interact with digital applications, ensuring that applications are accessible to everyone is both a moral and legal requirement. Web accessibility standards, such as WCAG (Web Content Accessibility Guidelines), provide comprehensive guidelines for making web content more accessible to people with disabilities.

Accessible applications often implement various features to support users with different abilities. These features include keyboard navigation, screen reader compatibility, proper color contrast, and ARIA properties that provide semantic meaning to web elements. ARIA attributes help bridge the gap between native HTML elements and custom widgets, ensuring that assistive technologies can correctly interpret and interact with these elements.

• Key accessibility features that modern applications should include:
• Keyboard navigability
• Screen reader compatibility
• Proper color contrast
• Alternative text for images
• Focus management
• ARIA properties for custom widgets

As automation testers, understanding these accessibility features is essential for creating comprehensive test cases that verify not just the functional aspects of an application but also its accessibility compliance.

UFT's Handling of Standard Objects vs. Accessibility Objects

UFT treats standard UI elements and accessibility objects differently based on their properties and behaviors. Standard objects, such as buttons, text fields, and dropdown lists, typically have well-defined properties that UFT can easily identify using its default identification settings. These objects usually follow standard patterns and behaviors, making them relatively straightforward to automate.

Accessibility objects, on the other hand, present unique challenges for UFT. These objects often implement custom behaviors and may not have the standard properties that UFT relies on for identification. For example, a custom-built accordion menu implemented with divs and spans may not have the native properties of a standard accordion component. In such cases, UFT needs to be configured to identify these objects using their specific properties or by adding them to the Object Repository manually.

When dealing with accessibility objects, testers often need to:

• Customize the Object Identification settings to include properties specific to accessibility elements
• Use descriptive programming to identify objects when they cannot be added to the Object Repository
• Implement regular expressions to handle dynamic properties that change during runtime
• Leverage the Test Object Model to programmatically interact with objects that are difficult to identify through standard methods

Understanding the differences between how UFT handles standard and accessibility objects is crucial for creating reliable test scripts that can accurately interact with all elements in an application.

Working with ARIA Properties in UFT

ARIA (Accessible Rich Internet Applications) properties play a vital role in making web applications accessible to users with disabilities. These properties provide additional semantic information about elements that may not be conveyed through standard HTML. ARIA attributes include roles, states, and properties that help assistive technologies understand and interact with web elements.

UFT has built-in support for identifying and working with ARIA properties. When recording or running tests on web applications that use ARIA, UFT can recognize these properties and include them in the Object Repository. This capability allows testers to create scripts that specifically target elements based on their ARIA attributes, ensuring that accessibility features are properly tested.

For example, if a web application uses the aria-expanded property to indicate whether a dropdown menu is expanded or collapsed, UFT can identify and interact with this element based on this property. Similarly, testers can use the aria-label or aria-labelledby properties to identify elements that may not have visible text but are still important for accessibility.

' Example of working with ARIA properties in UFT
' This script checks if a collapsible menu is expanded and clicks it if it's collapsed

Set objCollapsibleMenu = Browser("Browser").Page("Page").WebEdit("aria-expanded:=false")
If objCollapsibleMenu.Exists Then
    objCollapsibleMenu.Click
    Reporter.ReportEvent micPass, "Menu Click", "Successfully clicked the collapsible menu"
Else
    Reporter.ReportEvent micFail, "Menu Click", "Collapsible menu not found or already expanded"
End If

Another important aspect of working with ARIA properties in UFT is the ability to verify these properties during test execution. Testers can create checkpoints to validate that ARIA attributes are correctly set based on the application's state. For instance, after expanding a menu, a tester can verify that the aria-expanded property has been updated to "true".

' Example of verifying ARIA properties in UFT
' This script verifies that a menu's aria-expanded property is set to true after clicking it

Set objCollapsibleMenu = Browser("Browser").Page("Page").WebEdit("aria-expanded:=true")
If objCollapsibleMenu.Exists Then
    ' Get the current value of the aria-expanded property
    currentValue = objCollapsibleMenu.GetROProperty("aria-expanded")
    
    If currentValue = "true" Then
        Reporter.ReportEvent micPass, "ARIA Verification", "Menu is correctly expanded"
    Else
        Reporter.ReportEvent micFail, "ARIA Verification", "Menu is not expanded as expected"
    End If
Else
    Reporter.ReportEvent micFail, "ARIA Verification", "Menu not found after clicking"
End If

By leveraging UFT's capabilities to work with ARIA properties, testers can create comprehensive tests that verify both the functional and accessibility aspects of an application.

Best Practices for Testing Accessible Applications

Testing accessible applications requires a different approach than standard functional testing. When working with accessibility objects and ARIA properties in UFT, testers should follow several best practices to ensure comprehensive coverage and reliable test execution.

First, it's essential to understand the accessibility requirements and standards that the application aims to meet. This knowledge helps testers create appropriate test cases that verify accessibility compliance. Testers should familiarize themselves with WCAG guidelines and other accessibility standards to identify the critical areas that need testing.

Second, testers should leverage UFT's Object Repository effectively. When dealing with accessibility objects, it's often beneficial to add these objects to the Object Repository with specific identification properties that ensure reliable recognition. For objects that cannot be added to the Object Repository, descriptive programming can be used to identify them based on their unique properties.

• Key best practices for testing accessible applications with UFT:
• Understand the application's accessibility requirements and standards
• Customize Object Identification settings for accessibility objects
• Use descriptive programming for objects that cannot be added to the Object Repository
• Implement checkpoints for ARIA properties to verify accessibility features
• Combine functional and accessibility tests for comprehensive coverage
• Regularly update test scripts when accessibility objects change

Another important practice is to combine functional and accessibility testing. By integrating accessibility checks into existing functional tests, testers can ensure that accessibility features are tested as part of the overall test suite. This approach not only saves time but also helps identify accessibility issues early in the development process.

Finally, testers should document their accessibility testing approach and results. This documentation helps in maintaining consistency across test cycles and provides valuable insights for improving accessibility testing practices.

Troubleshooting Common Object Identification Issues

Despite UFT's robust object identification capabilities, testers may encounter issues when working with accessibility objects and ARIA properties. These issues can range from objects not being recognized to incorrect identification leading to test failures.

One common issue is objects not being added to the Object Repository. This can happen when UFT cannot uniquely identify the object using the default identification properties. To resolve this, testers can customize the Object Identification settings to include properties specific to accessibility objects or use descriptive programming to identify these objects programmatically.

Another frequent problem is dynamic object properties. Accessibility objects often have properties that change during runtime, such as the aria-expanded property that toggles between "true" and "false". To handle such cases, testers can use regular expressions in the Object Identification settings or create dynamic descriptions in their test scripts.

<!-- Example of ARIA attributes in a web application -->
<!-- This HTML shows a collapsible menu with ARIA properties -->

<div class="accordion-menu" role="tablist">
  <div class="menu-item" role="tab" id="menu1" aria-expanded="false" aria-controls="panel1">
    <button aria-label="Toggle Menu 1">Menu 1</button>
  </div>
  <div class="menu-panel" id="panel1" role="tabpanel" aria-labelledby="menu1" hidden>
    <ul>
      <li><a href="#">Item 1</a></li>
      <li><a href="#">Item 2</a></li>
    </ul>
  </div>
</div>

When troubleshooting object identification issues, it's important to use UFT's Object Spy tool to examine the properties of accessibility objects. This tool provides detailed information about an object's properties, methods, and events, helping testers identify the best properties to use for object identification.

Additionally, testers should regularly update their Object Identification settings to reflect changes in the application. As applications evolve, the properties of accessibility objects may change, requiring updates to the identification settings to ensure reliable test execution.
