My Current “Waiter” Class used by WebDriver Tests

My Current “Waiter” Class used by WebDriver automation tests, so keep away from your hard coded Thread.sleep() :

 import java.util.List;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.WebElement;  
 import org.openqa.selenium.support.ui.WebDriverWait;  
 import com.google.common.base.Function;  
 /*  
  * Two usage examples in your test code:  
  * MyWaiter myWaiter = new MyWaiter(driver);  
   WebElement search = myWaiter.waitForMe(By.name("btnG"), 10);  
   or  
   if(!myWaiter.waitForMe(By.name("btnG"), 1, 10)) return;  
   or if (!myWaiter.waitForMeDisappear(By.name("btnG"), 10)) return;  
  */  
 public class MyWaiter {  
      private WebDriver driver;  
      public MyWaiter(WebDriver driver){  
           this.driver = driver;  
      }  
      public WebElement waitForMe(By locatorname, int timeout){  
           WebDriverWait wait = new WebDriverWait(driver, timeout);  
           return wait.until(MyWaiter.presenceOfElementLocated(locatorname));  
      }  
      //Given certain number of web element to see if it is found within timeout  
      public Boolean waitForMe(By locatorname, int count, int timeout) throws InterruptedException{  
           long ctime = System.currentTimeMillis();  
           while ((timeout*1000 > System.currentTimeMillis()- ctime)){  
                List<WebElement> elementList = driver.findElements(locatorname);  
                if ((elementList.size()< count)){  
                     Thread.sleep(300);  
                }  
                //element is found within timeout   
                else  
                     return true;  
           }  
           // otherwise element is not found within timeout  
           return false;  
      }

      public Boolean waitForMeDisappear(By locatorname, int timeout) throws InterruptedException{  
           long ctime = System.currentTimeMillis();  
           while ((timeout*1000 > System.currentTimeMillis()- ctime)){  
                List<WebElement> elementList = driver.findElements(locatorname);  
                if ((elementList.size()!= 0)){  
                     Thread.sleep(300);  
                }  
                //element is Disappear within timeout   
                else  
                     return true;  
           }  
           // otherwise element is still show up within timeout  
           return false;  
      }  
      public static Function<WebDriver, WebElement> presenceOfElementLocated(final By locator) {  
           // TODO Auto-generated method stub  
           return new Function<WebDriver, WebElement>() {  
                @Override  
                public WebElement apply(WebDriver driver) {  
                     if (driver.findElement(locator)!= null){  
                          return driver.findElement(locator);  
                     }  
                     else return null;  
                }  
           };  
      }  
 }  

Another useful method on implicitwait(), I also wrote a post related to it, FYI : http://joychester.blogspot.com/2010/09/webdriver-wait-is-easier-after-using.html
