A .NET library for automated UI testing of Windows applications using Microsoft's UI Automation framework.
FlaUI is a .NET library for automated UI testing of Windows applications, including Win32, WinForms, WPF, and Store Apps. It wraps Microsoft's native UI Automation libraries (UIA2 and UIA3) to provide a reliable and modern framework for interacting with and validating UI elements programmatically.
.NET developers and QA engineers who need to automate testing for Windows desktop applications, particularly those working with WinForms, WPF, or Store Apps and seeking a free, open-source alternative to commercial tools.
Developers choose FlaUI for its clean, maintainable codebase, dual support for UIA2 and UIA3 to handle different application types, and its focus on being a straightforward wrapper around Microsoft's UI Automation libraries without unnecessary complexity.
UI automation library for .Net
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows switching between UIA2 and UIA3 to handle different Windows application types, addressing compatibility issues as highlighted in the README's FAQ section.
Rewritten from scratch for better maintainability and collaboration, improving upon older projects like TestStack.White, as stated in the introduction.
Covers almost all UI Automation functionality while exposing native objects for advanced use cases, ensuring flexibility for uncovered scenarios.
Provides methods to launch, attach to, and close applications, simplifying test setup and teardown, as shown in the code examples.
UIA3 has known compatibility issues with WinForms applications, requiring developers to fall back to UIA2 for reliable testing, as admitted in the README.
Lacks built-in test recording or GUI tools, making it less accessible for teams preferring codeless or visual testing approaches without additional tooling.
Has fewer integrations, plugins, and community resources compared to commercial solutions like TestComplete, which might increase development overhead for complex setups.
FlaUI is an open-source alternative to the following products:
CodedUI is a Microsoft testing framework for automated UI-driven functional testing of Windows applications.
An automated UI testing tool by SmartBear for functional testing of desktop, web, and mobile applications across various platforms.
Ranorex is a commercial test automation framework for desktop, web, and mobile applications that provides GUI testing with recording and scripting capabilities.
