WinAppDriver is Microsoft's official open-source tool for automating Windows desktop applications. It implements the familiar Appium protocol, enabling developers and testers to write automated tests for Windows apps in any Appium-supported language. WinAppDriver supports testing Universal Windows Platform (UWP), Windows Forms (WinForms), Windows Presentation Foundation (WPF), and Classic Windows (Win32) apps.

Windows Application Driver is a service to support Selenium-like UI Test Automation on Windows Applications.

So you can create automated test scripts that simulate user interactions with native Windows applications, such as launching the app, finding and clicking UI elements, entering text, and reading attributes. WinAppDriver provides a range of locator strategies for finding elements, including accessibility IDs, names, class names, and XPaths.

Key Features

  • Testing Universal Windows Platform (UWP)
  • Windows Presentation Foundation (WPF)
  • Windows Forms (WinForms)
  • Classic Windows (Win32) apps on Windows 10 PCs.
  • The Windows Application Driver complies with the JSON Wire Protocol standard and some application management functionalities defined by Appium.



Takes advantage of the industry-standard WebDriver Protocol Developed by Microsoft

Not useful if you don’t have to automate Oracle applications. Had not bee updated in years.

UPDATE: Look like development on WinAppDriver has been paused. And based on the comments in the update, it looks like it may not be a good option going forward (thanks to Peter Thomas for letting me know about this).

Do you love using Python as your go-to language for everything and also need to automate Windows desktop applications? If so, check out pywinauto.

It describes itself as a GUI automation library written in pure Python and well developed for Windows GUI. At its simplest, it allows you to send mouse and keyboard actions to dialogs and controls on both Windows and Linux, while more complex text-based actions are supported on Windows only thus far (Linux AT-SPI support is under development).

The latest release introduced MS UI Automation (UIA) support, which includes WinForms, WPF, Qt browsers, Store apps-based tests, and more.  

Key Features

  • Cross-Backend Support: Pywinauto supports both Win32 API (default) and MS UI Automation, offering broad compatibility with various Windows applications.
  • Selenium-Like Syntax for Windows Applications: Offers a familiar, Selenium-like interface for automating Windows GUI elements, making it easier for testers familiar with web testing to adapt.
  • Pythonic Approach to Automation: Utilizes Python's simplicity and power to make script writing more efficient and readable, even for complex automation tasks.
  • Cross-Platform User Input Emulation: Beyond Windows, it supports user input emulation (mouse and keyboard actions) on Linux, expanding its utility in cross-OS testing environments.
  • Extensive Documentation: Comprehensive documentation, including a Getting Started Guide and examples, ensures a smooth learning curve for new users.



Since this is a Python library, it is great for testers already using Python. I love Python, so I'm calling it a pro, lol.

It uses Python. Believe it or not, there are some weirdos out there that don't like Python.

SikuliX can help automate anything you see on the screen of your desktop computer running Windows, Mac, or some Linux/Unix. SikuliX uses image recognition powered by OpenCV to identify and control GUI components.

By simply identifying elements on the screen via screenshots, SikuliX allows users to automate tasks across any application, regardless of the programming language or technology it was built with. Suitable for both testers and developers, SikuliX streamlines the process of automation testing, making it an indispensable tool for quality assurance and repetitive task automation.

With its Python scripting capabilities, SikuliX stands out for its ease of use and flexibility, catering to a wide range of automation needs from testing to daily task automation.

Years ago, I spoke with the main developer and maintainer of SikuliX, Raimund Hocke, on Episode 40 of my automation testing podcast.

After speaking with Raimund, I thought it would be helpful to create a quick video to demonstrate just how easy it is to get started with SikuliX.

Key Features

  • Cross-Platform Support: SikuliX runs on Windows, macOS, and most Linux/Unix systems, offering a versatile solution for desktop automation across different environments.
  • Image Recognition Technology: Utilizes OpenCV to identify and interact with GUI components based solely on screenshots, making it highly effective for applications where accessing the internal GUI structure is challenging.
  • Multiple Scripting Languages: Supports scripting in Python (via Jython), Ruby (via JRuby), JavaScript, and allows for usage in Java programming, ensuring flexibility for developers and testers with varying programming preferences.
  • Robot Framework Integration: Provides support for running RobotFramework text-scripts, enhancing its capabilities in automated testing scenarios.
  • Remote and Multi-Monitor Environments: Capable of automating tasks on remote systems and in multi-monitor setups, extending its utility in complex testing environments.
  • Basic OCR Capabilities: Comes with built-in text recognition features powered by Tesseract, enabling search and interaction based on text within images.
  • Extensive Documentation and Community Support: Offers comprehensive documentation and a strong community for users to seek help, share knowledge, and contribute to the project.



Good option if you have an application that needs to be tested that has controls that aren’t recognized by other solutions

Image-based automation is tricky and often time unreliable. I would use this approach only as a last resort.

Appium Desktop

You might be thinking — Appium? Isn't that just for mobile automation testing?

While that is one of its primary uses, the main contributor and the father of the modern Appium we all know and love Jonathan Lipps, reminded me that Appium bundles WinAppDriver as well as Appium4Mac, which can be used to automate Mac desktop applications!

Excitingly, the Appium project has a vision of becoming the universal protocol for automating all kinds of apps, not just mobile. “Drivers” for Windows, Mac, and IoT apps are expanding what is possible.

Because of this I'd like to spend a little more time going over common questions asked around Appium native application testing.

What are the challenges associated with Appium in terms of setup and configuration?

The challenges associated with Appium in terms of setup and configuration include limited support for certain native mobile features like GPS, camera, and battery status. Furthermore, its setup and configuration processes may be complex, especially for beginners, which can pose difficulties for users who are new to the framework.

What testing frameworks does Appium support?

Appium supports various testing frameworks, including TestNG, JUnit, and Mocha. By accommodating these popular testing frameworks, Appium enables users to harness their preferred tools effectively to enhance test automation.

In which programming languages can users write tests in Appium?

Users can write tests in Appium using a range of programming languages, including but not limited to Java, Ruby, Python, and JavaScript. The flexibility provided by Appium allows testers to choose a language that best suits their skill set and project requirements. This versatility in language selection enables seamless integration with various development environments, offering developers the freedom to work in their preferred programming language while leveraging the capabilities of Appium for mobile app testing.

Which platforms does Appium support for testing?

Appium provides the capability to conduct testing on both iOS and Android platforms, offering robust support for ensuring cross-platform compatibility in mobile applications. 



Most testers are already familiar with Appium

Some functionality relies on WinAppDriver, and as I mentioned earlier, this project is currently on hold by Microsoft.
