The Lightweight Test Automation Framework for ASP.NET was developed and is currently used by the ASP.NET QA Team to automate regression tests for the product. It is designed to run within an ASP.NET application.
Tests can be written in any .NET Framework language. They use an API to manipulate and verify the DOM of the browser. The Lightweight Test Automation Framework supports running tests in Microsoft Internet Explorer, Mozilla Firefox, Apple Safari, and Opera.
This release contains two downloads. One download contains the source code and unit tests for the automation framework. It also includes a sample Web site that demonstrates how to use the test framework. The second download contains only the sample Web site. Use this download if you want only the compiled binaries and do not need the source code and unit tests.
You can find information on the future of the Lightweight Test Automation Framework for ASP.NET in the ASP.NET QA Roadmap
and instructions on how to use the framework in the Lightweight Test Automation Framework for ASP.NET Samples Release Notes
