Synchronizing a test with custom-expected conditions

The Selenium WebDriver also provides a way to build custom-expected conditions along with common conditions using the ExpectedCondition class. This comes in handy when a wait can be handled with a common condition supported by the ExpectedCondition class.

In this recipe, we will explore how to create a custom condition.

How to do it...

We will create a test that will create a wait until an element appears on the page using the custom ExpectedCondition class as follows:

@Test
public void testExplicitWait()
{
    //Go to Sample Application
    WebDriver driver = new FirefoxDriver();
    driver.get("http://dl.dropbox.com/u/55228056/AjaxDemo.html");
    
    try {
        //Get the link for Page 4 and click on it, this will call AJAX code 
        //for loading the contents for Page 4
        WebElement page4button = driver.findElement(By.linkText("Page 4"));
        page4button.click();
    
        //Create Wait using WebDriverWait. 
      ...
