Automating Desktop Applications Using Tosca

As software development becomes increasingly complex, the need for reliable and efficient test automation continues to grow. While many testing tools focus solely on web or mobile applications, Tricentis Tosca stands out with its capability to automate desktop applications. Tosca’s model-based test automation approach makes it particularly powerful for testing legacy systems, enterprise software, and desktop environments.

In this blog, we'll explore how Tosca is used for automating desktop applications, its advantages, and the steps to get started.


Why Automate Desktop Applications?

Many businesses still rely heavily on desktop-based applications—from enterprise resource planning (ERP) systems to custom-built internal tools. Manual testing of these applications can be time-consuming, error-prone, and costly.

By automating desktop application testing, organizations can:

  • Improve test accuracy and consistency
  • Reduce testing time and costs
  • Enable faster release cycles
  • Ensure better coverage of critical workflows


Why Choose Tosca for Desktop Automation?

Tosca supports desktop application automation natively and excels due to:

  • Model-Based Testing: Rather than scripting, Tosca allows testers to build reusable business components using a visual, drag-and-drop interface.
  • Robust UI Recognition: Tosca uses OCR, UIA (UI Automation), and Win32 engines to recognize and interact with desktop elements, even in complex UIs.
  • No-Code Interface: Non-technical users can easily create and maintain test cases.
  • Data-Driven Testing: Tosca’s TestCase Design and Test Data Management modules allow dynamic, scalable testing across data sets.
  • Seamless Integration: Works well with CI/CD tools and supports end-to-end automation across web, mobile, and desktop platforms.


How Tosca Automates Desktop Applications

1. Scan the Application

Use Tosca’s XScan (Tosca Scanner) to recognize and capture the UI elements of your desktop application. It supports multiple technologies including WinForms, WPF, Java, Delphi, and SAP.

  • Open XScan from Tosca Commander.
  • Launch the desktop app to be tested.
  • Hover over and capture the required UI controls (buttons, text fields, lists, etc.).
  • Save the scanned module.


2. Create Test Cases

After capturing the UI elements:

  • Drag and drop the scanned elements into your test case.
  • Add test steps by defining input values, click actions, verifications, etc.
  • Use Tosca’s inbuilt conditions and loops to handle business logic.


3. Parameterization and Reusability

  • Use TestCase Design to create parameterized test templates.
  • Link with test data from Excel or Tosca TDM (Test Data Management).
  • Reuse modules across different test cases for maintainability.


4. Execute the Test

  • Use Tosca ExecutionLists to define and execute your test scenarios.
  • Generate reports and logs for debugging and documentation.
  • Schedule tests via Tosca CI/CD integration or Execution Server for continuous testing.


Challenges and Best Practices

While Tosca simplifies desktop automation, testers should be aware of potential challenges:

  • Dynamic UI Elements: Use wildcarding and buffer techniques to handle dynamic values.
  • Performance Considerations: Ensure the app under test is stable before automation.
  • Version Compatibility: Update modules if the application UI changes in future releases.

Best practices include keeping test cases modular, maintaining a clean repository structure, and regular reviews of scan modules.


Conclusion

Tosca makes desktop application automation accessible and efficient with its model-based, no-code approach. It enables testers to focus on business logic rather than programming, improving speed, accuracy, and collaboration. Whether you're automating a legacy ERP tool or a modern desktop utility, Tosca provides the features and flexibility to ensure high-quality test coverage.

How to Use Tosca's Test Configuration Parameters

Tosca by Tricentis is a powerful model-based test automation tool widely used in enterprise environments for end-to-end testing. One of its most useful features is Test Configuration Parameters (TCPs), which provide flexibility and control in managing test execution. TCPs enable testers to create reusable test cases by passing dynamic values without hardcoding them. This significantly enhances test maintenance, scalability, and efficiency. In this blog, we’ll explore what Test Configuration Parameters are, how to create and use them, and the best practices to follow when working with TCPs in Tosca. What Are Test Configuration Parameters? Test Configuration Parameters are custom-defined key-value pairs that can be associated with test cases, test case folders, or execution lists in Tosca. They help manage configuration data such as environment URLs, browser types, credentials, or any other variable data that may differ across test runs. By using TCPs, you can avoid duplicating test case...

Using Hibernate ORM for Fullstack Java Data Management

In the world of fullstack Java development, managing data efficiently and seamlessly across the application is critical. One of the most powerful tools in the Java ecosystem for handling database operations is Hibernate ORM (Object-Relational Mapping). Hibernate simplifies the interaction between Java applications and relational databases, reducing boilerplate code and improving maintainability. This blog explores how Hibernate ORM works, why it’s widely used, and how it fits into the data management strategy of a fullstack Java application. What is Hibernate ORM? Hibernate ORM is an open-source Java framework that provides a powerful and flexible mechanism for mapping Java objects to database tables. It abstracts the low-level JDBC code, allowing developers to work with high-level object-oriented concepts. Instead of writing raw SQL queries, Hibernate allows developers to define database interactions using simple Java classes (also known as POJOs) and annotations or XML configurations...
