Understanding UFT's architecture, particularly its object repository management, is essential for maximizing its potential and creating maintainable, scalable test automation frameworks.

Anatomy of UFT's Object Repository

An object repository in UFT is essentially a database that stores information about objects in the application under test. When you record a test in UFT, the tool identifies objects based on their properties and stores them in the repository. Each object entry includes properties that uniquely identify the object, such as its name, type, and other identifying attributes like HTML tag, ID, or other relevant properties.

The object repository structure is hierarchical, with objects organized based on their location in the application's user interface. Objects are typically stored as parent-child relationships, reflecting their actual hierarchy in the application. For example, a button might be stored as a child of a window, which itself might be a child of the application object.

UFT uses this stored information during test execution to locate objects in the application. When a test step references an object, UFT compares the properties stored in the repository with the actual properties of objects in the running application. If UFT finds an object that matches the properties in the repository, it can execute the action; otherwise, the test fails.

Key components of UFT's object repository:

• Object properties that uniquely identify each UI element
• Object hierarchy reflecting the application's structure
• Methods and properties available for each object type
• Test object classes that map to actual application objects

Understanding this anatomy is crucial for effective UFT's internal object repository management, as it helps you make informed decisions about how to organize and maintain your repositories for optimal test performance and reliability.

Local vs. Shared Object Repositories in UFT

UFT offers two primary types of object repositories: local and shared. Each serves different purposes and offers distinct advantages for UFT's internal object repository management.

A local object repository is associated with a specific test and stored within the test itself. This means the repository is created, modified, and maintained independently of other tests. Local repositories are ideal when you're working on a small number of tests that are unlikely to be reused or shared across different test scripts. They offer simplicity and isolation, as each test has its own repository that doesn't interfere with others.

Shared object repositories, on the other hand, can be accessed by multiple tests. They are stored as separate files that can be linked to various tests. Shared repositories are beneficial when multiple tests need to interact with the same set of objects, as they allow for centralized management and consistency. This approach reduces redundancy and makes maintenance easier, as changes to objects in the shared repository automatically apply to all tests using it.

When deciding between local and shared repositories, consider factors like:

• The number of tests that will use the objects
• The frequency of changes to the application
• The need for consistency across tests
• The complexity of your automation framework

When to choose each type:

• Local repositories: Small test suites, unique objects per test, limited collaboration
• Shared repositories: Large test suites, common objects across tests, team environments, applications that change frequently

Understanding these differences is essential for effective UFT's internal object repository management, as it directly impacts the maintainability, scalability, and reliability of your automated tests.

Creating and Managing Object Repositories

Creating and managing object repositories effectively is a cornerstone of successful UFT automation. The process begins with understanding your application's structure and identifying which objects need to be stored in repositories.

To create a new object repository in UFT, you can use the Object Repository Manager, a dedicated tool that provides an interface for managing repositories. From here, you can create new repositories, either local or shared, and specify where they should be stored. When creating a repository, it's important to consider an organizational strategy that will make the repository easy to navigate and maintain as it grows.

Adding objects to repositories can be done through several methods:

• Recording tests, which automatically captures objects
• Manually adding objects using the Object Spy tool
• Importing objects from other repositories
• Adding objects programmatically

Proper organization is critical for effective object repository management. Consider organizing objects logically based on modules, pages, or functionality. This makes it easier to locate and maintain objects as your test suite grows. Additionally, use meaningful naming conventions for objects and repositories to enhance readability and maintainability.

Best practices for repository management:

• Regularly review and clean up unused objects
• Document changes to repositories
• Implement version control for shared repositories
• Establish naming conventions and stick to them
• Use consistent naming patterns
• Group related objects together
• Regularly audit repositories for duplicates or obsolete objects
• Document complex or custom properties

By following these practices, you can ensure your repositories remain organized, efficient, and easy to maintain throughout the lifecycle of your automation projects.

Advanced Object Repository Management Techniques

As your automation framework matures, you'll need to implement advanced techniques for object repository management. These techniques help address challenges that arise with larger test suites and more complex applications.

Merging repositories is a common technique when working with shared repositories. If you have multiple repositories that contain similar or related objects, you can merge them into a single repository to improve organization and reduce redundancy. The Object Repository Manager provides functionality to merge repositories while preserving object properties and relationships.

For very large repositories, you might consider splitting them into smaller, more manageable components. This can improve performance and make maintenance easier. When splitting repositories, consider logical boundaries such as modules, features, or pages to ensure objects are grouped meaningfully.

Descriptive programming offers an alternative approach to traditional repository management. Instead of storing object properties in repositories, you can specify them directly in your test scripts. This technique provides flexibility and can be useful for dynamic objects or when working with applications that have frequently changing interfaces.

Repository maintenance is an ongoing process that includes:

• Regular audits to identify and remove duplicate or obsolete objects
• Updating object properties when applications change
• Optimizing repository structure for better performance
• Implementing version control to track changes

These advanced techniques can significantly enhance your object repository management, making your automation framework more robust, maintainable, and scalable as your testing needs evolve.

Code Examples for Object Repository Management

' Example 1: Creating a new object repository programmatically
Dim objRepository
Set objRepository = CreateObject("QuickTest.Application.ObjectRepository")
objRepository.Create "C:\TestRepositories\MyLocalRepository.tsr"
objRepository.Add "Browser", "MyBrowser", "micClass"
objRepository.Add "Page", "MyPage", "micClass", "Browser"
objRepository.Save
Set objRepository = Nothing

' Example 2: Adding an object to a shared repository
Dim objRepository
Set objRepository = CreateObject("QuickTest.Application.ObjectRepository")
objRepository.Open "C:\TestRepositories\SharedRepository.tsr", True, True

' Add a new button object
objRepository.Add "Button", "SubmitButton", "micClass", "Window", "MainWindow", _
    "html id:=submitBtn", "html tag:=INPUT"

objRepository.Save
Set objRepository = Nothing

' Example 3: Using descriptive programming to reference objects
' Instead of using repository objects, specify properties directly
Browser("Browser").Page("Page").WebButton("html id:=submitBtn").Click

' Or using the Description object
Set btnDesc = Description.Create()
btnDesc("html id").Value = "submitBtn"
btnDesc("micclass").Value = "WebButton"
Browser("Browser").Page("Page").WebElement(btnDesc).Click

Optimizing Object Repository Performance

As your automation suite grows, the performance of your object repositories can become a critical factor in test execution speed and overall efficiency. Optimizing object repository performance involves several strategies that ensure quick access to objects and minimal overhead during test execution.

One key optimization technique is to minimize the size of your object repositories by removing unused or obsolete objects. Over time, repositories can accumulate objects that are no longer referenced by any tests, cluttering the repository and slowing down access times. Regular audits and cleanup sessions can help maintain repository efficiency.

Another important consideration is the organization structure of your repositories. A well-organized repository with logical hierarchies and naming conventions allows UFT to locate objects more quickly during test execution. Implementing consistent patterns and avoiding deeply nested folder structures can significantly improve access times.

For shared repositories in particular, performance optimization requires special attention to network access and concurrent usage. When multiple tests access the same shared repository simultaneously, proper locking mechanisms and connection management become essential to prevent bottlenecks and ensure smooth test execution.

Strategies for optimizing shared repository performance:

• Implement proper connection management
• Use version control for repository changes
• Consider splitting large repositories into smaller, focused ones
• Regular maintenance and cleanup of obsolete objects

Maintaining object repository performance is not just about speed—it's also about ensuring the reliability and maintainability of your automated tests. By implementing these optimization techniques, you can create a scalable automation framework that grows efficiently with your testing needs while maintaining consistent performance across all test executions.
