Hey there! I’ve successfully automated C# WPF applications using Robot Framework after struggling with the exact same tools you mentioned—let me share what worked.

First, let’s quickly cover why your current attempts aren’t panning out:

• White Library: The project has been largely unmaintained for years, so it doesn’t play nicely with modern WPF frameworks and newer .NET versions. I ran into crashes and unresponsive element detection too.
• AutoItLibrary: It’s designed for legacy Win32 applications, not WPF’s UI Automation-based controls. It can’t parse WPF’s underlying component hierarchy, hence why it can’t detect your elements.
• Sikuli: Image recognition is inherently brittle for WPF apps—scalable UI elements, resolution changes, or even minor styling tweaks will break your tests instantly.

The Reliable Solution: WinAppDriver + AppiumLibrary #

The best approach is using WinAppDriver (Microsoft’s official UI automation tool for Windows apps) paired with Robot Framework’s AppiumLibrary. Here’s how to set it up:

1. Prepare WinAppDriver

   • Enable Developer Mode on your Windows machine (go to Settings > Update & Security > For developers).
   • Download and install WinAppDriver from Microsoft’s official distribution.
   • Launch WinAppDriver—you’ll see a command prompt window open, listening for connections on http://127.0.0.1:4723.

2. Install the Required Robot Library
   Run this command in your terminal to install AppiumLibrary:

   pip install robotframework-appiumlibrary
   

3. Write Your Test Case
   The key to stable WPF automation is using AutomationId for every control you need to interact with. Make sure you set unique AutomationId values in your C# WPF code (this is far more reliable than text or XPath locators).

   Here’s a sample Robot test case to get you started:

   *** Settings ***
   Library    AppiumLibrary
   
   *** Test Cases ***
   Interact with WPF App
       # Launch the WPF application
       Open Application    http://127.0.0.1:4723/wd/hub    platformName=Windows    app=C:\YourAppPath\YourWPFApp.exe
       # Click a button using its AutomationId
       Click Element    automation_id=SaveSettingsButton
       # Input text into a text field
       Input Text    automation_id=UserEmailField    test@example.com
       # Close the app
       Close Application
   

Pro Tips for Success #

• Use Inspect.exe (included with the Windows SDK) to explore your WPF app’s UI hierarchy and find AutomationIds for elements.
• Avoid using text-based locators—WPF apps often have dynamic or localized text that breaks tests.
• If you need to run tests headlessly or on a CI server, you can configure WinAppDriver to run as a service instead of a console app.
