Testing RIAs with WebDriver

If you need to test Rich Internet Applications from Java, take a look at Webdriver.

Things I like about it:

• It uses real browsers to run the tests, quirks and all
• It's got a literate testing interface based on Hamcrest and inspired by LiFT.

Here's a very simple example.It's doing simple tests on a static html site:

public class HomePageTest extends HamcrestWebDriverTestCase {
   
   @Override
   protected WebDriver createDriver() {
      return new HtmlUnitDriver();
   }
   
   public void testHomePageHasTitleAndHeading()
         throws Exception {
      goTo("http://test.intranet");
      assertPresenceOf(title()
        .with(text(startsWith("Agile"))));
      assertPresenceOf(title()
        .with(text(containsString("Cocking and Co."))));
      assertPresenceOf(heading(1)
        .with(text(equalTo("Agile Application Development"))));
   }
}

This won't quite work out of the box, as there is no heading finder, but adding one is easy:

public class HeadingFinder extends HtmlTagFinder {
  private final int level;

  public HeadingFinder(int level) {
     this.level = level;
  }

  @Override
  protected String tagDescription() {
     return "heading level "+level;
  }

  @Override
  protected String tagName() {
     return "h"+level;
  }

  public static HeadingFinder heading(int level) {
     return new HeadingFinder(level);
  }
}

It's fairly new, but there are now pre-built binaries available.
