NUnitAsp
NUnitAsp is a tool for automatically testing ASP.NET web pages. It's an extension to NUnit, a tool for test-driven development in.NET.
How it works
NUnitAsp is a class library for use within NUnit tests. It provides NUnit with the ability to download, parse, and manipulate ASP.NET web pages.With NUnitASP, tests do not need to know how ASP.NET renders controls into HTML. Instead, NUnitASP library can do this, keeping the test code simple and clean. For example, tests don't need to know that a DataGrid control renders as an HTML table; NUnitASP handles the details. This gives users freedom to focus on functionality questions, like whether the DataGrid holds the expected values.
public void TestExample
NUnitAsp can test complex web sites involving multiple pages and nested controls.
