title: Handling New Web Browser Window in Selenium WebDriver
body: <p>When I click on Help Screen in a web page, it opens a new web browser window containing information of of help webpage. I wanted to read some text or title of that webpage, but i can't able to read anything of that help window. The main objective in this case is to verify the help screen content and close that help window after verifying the help screen. The code i'm using is as follows:</p>
  
  <p>public void  verifyNewWindow(String buttonId, String screenShotFileName)
      {</p>
  
  <pre><code>    String winHandleBefore = driver.getWindowHandle();
      clickOnButton(buttonId); //Clicking on help button on a webpage, help id is passed from baseclass)
      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
      for(String winHandle : driver.getWindowHandles()){
          if(!winHandle.equals(winHandleBefore))
          {
              driver.switchTo().window(winHandle);
              takeScreenShot(screenShotFileName);
              driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
              driver.close();
              break;
  
          }
      }
             driver.switchTo().window(winHandleBefore);
  }
  </code></pre>
