Unit testing aspx pages with WatiN tool

I just read a post on GridViewGuy blog that introduces a great tool for testing aspx pages - WatiN, and it really grabbed my attention. To put it in short, WatiN is a framework that will let you write unit test in order to test aspx pages functionality. "Inspired by Watir development of WatiN started in December 2005 to make a similar kind of Web Application Testing possible for the .Net languages. Since then WatiN has grown into an easy to use, feature rich and stable framework. WatiN is developed in C# and aims to bring you an easy way to automate tests with Internet Explorer." WatiN is written in C# and is licensed under Apache License 2.0. The important features are the support for Ajax pages, frames and iframes and popup dialogs. It supports testing in Internet Explorer 6, 7 and 8 and Firefox 2 as well. Now let's see some example. Take a look at the sample code that will search for keyword "MSForge" on Google in both IE and Firefox browsers. [Test] public void SearchForMSForge() { using (IBrowser ie = BrowserFactory.Create(BrowserType.InternetExplorer)) { ie.GoTo(http://www.google.com); ie.TextField(Find.ByName("q")).Value = "MSForge"; ie.Button(Find.ByName("btnG")).Click(); Assert.IsTrue(ie.ContainsText("MSForge")); } using (IBrowser firefox = BrowserFactory.Create(BrowserType.FireFox)) { firefox.GoTo(http://www.google.com); firefox.TextField(Find.ByName("q")).Value = "MSForge"; firefox.Button(Find.ByName("btnG")).Click(); Assert.IsTrue(firefox.ContainsText("MSForge")); } } As you can see it is similar to "classic" unit testing. Test methods should have [Test] attribute and have to return no data. You simple create a new instance of a browser and access any DOM element. After simulating a search behavior of a user, we can examine the results by well known Assert class. You can find more information on WatiN website and download WatiN package with binaries and samples from here. Happy testing :)
