Coded UI

Coded UI is a Microsoft testing framework that enables automated testing of user interfaces for Windows desktop applications and web applications. It integrates with Visual Studio, allowing testers and developers to create, maintain, and execute UI test scripts using C# or VB.NET. Coded UI supports record-and-playback functionality as well as coded test creation, making it easier to automate repetitive UI testing tasks. Though Microsoft has deprecated Coded UI in favor of newer technologies like Selenium and Playwright, it remains a useful tool in legacy environments for validating UI functionality and regression testing.

What is Coded UI Testing?

Coded UI Testing is a Microsoft Visual Studio framework used to create automated tests for validating user interfaces of desktop and web applications.


Coded UI supports testing of Windows desktop applications (WinForms, WPF), web applications (IE, Edge), and some other UI technologies supported by Microsoft.

Microsoft has deprecated Coded UI Testing, with no support for new UI frameworks and no updates beyond Visual Studio 2019. It is recommended to migrate to other tools like Selenium or Playwright.
