Yestarday I was looking for a way to test a web application having hundred of links that have a certain structure. After a question on StackOverflow I got the same answer a colleague of mine already had given, WatiN. WatiN enables you to open a certain web page in Internet Explorer or Firefox and interacting with the web page though code (like clicking, entering text in controls, …).

In my Unit Test Project (VS2008) I used Internet Explorer as this development is a little bit ahead of the Firefox development. To create cross browser WatiN tests, check this link. I’ll try to port my project to cross browser testing later.

There’s also a WatiN Test Recorder. The next Release of this looks very promising!

Here’s an example how you get started by opening an Internet Explorer Window and go to a certain web page.

1

IE ie = new IE("www.google.be");

Check if the page contains a certain text:

1

Assert.IsTrue(ie.ContainsText("..."));

To find a link and click on it:

1

ie.Link(Find.ByText("...")).Click();

Search for a certain TableCell:

1

ie.TableCell(Find.ByText("..."));

Click on a TableCell:

1

tableCell.Click();

Get all the TableCells of the current page:

1

ie.TableCells;

Search for a certain Frame:

1

Frame frame = ie.Frame(Find.BySrc(new Regex(".*main.aspx")));

Does a certain Element exists:

1

Assert.IsTrue(frame.Element("app").Exists);
