Test if element is present using Selenium WebDriver

Question

Is there a way how to test if an element is present  Any findElement method would end in an exception  but that is not what I want  because it can be that an element is not present and that is okay  that is not a fail of the test  so an exception can not be the solution   I ve found this post  Selenium c  Webdriver  Wait Until Element is Present But this is for C  and I am not very good at it  Can anyone translate the code into Java  I am sorry guys  I tried it out in Eclipse but I don t get it right into Java code   This is the code   public static class WebDriverExtensions      public static IWebElement FindElement this IWebDriver driver  By by  int timeoutInSeconds            if  timeoutInSeconds  gt  0               var wait   new WebDriverWait driver  TimeSpan FromSeconds timeoutInSeconds                return wait Until drv   gt  drv FindElement by                       return driver FindElement by

Personally  I always go for a mixture of the above answers and create a re-usable static Utility method that uses the size    gt  0 suggestion   public Class Utility             public static boolean isElementExist WebDriver driver  By by          return driver findElements by  size    gt  0             This is neat  re-usable  maintainable     all that good stuff  -

Use findElements instead of findElement   findElements will return an empty list if no matching elements are found instead of an exception   To check that an element is present  you could try this  Boolean isPresent   driver findElements By yourLocator  size    gt  0   This will return true if at least one element is found and false if it does not exist   The official documentation recommends this method      findElement should not be used to look for non-present elements  use findElements By  and assert zero length response instead

You can make the code run faster by shorting the selenium timeout before your try catch statement   I use the following code to check if an element is present   protected boolean isElementPresent By selector        selenium manage   timeouts   implicitlyWait 1  TimeUnit SECONDS       logger debug  Is element present  selector       boolean returnVal   true      try          selenium findElement selector         catch  NoSuchElementException e           returnVal   false        finally           selenium manage   timeouts   implicitlyWait 15  TimeUnit SECONDS             return returnVal

if you are using rspec-Webdriver in ruby  you can use this script assuming that an element should really not be present and it is a passed test   First  write this method first from your class RB file  class Test  def element present      begin         browser find element  name   this element id  displayed          rescue Selenium  WebDriver  Error  NoSuchElementError             puts  this element should not be present          end  end   Then  on your spec file  call that method     before  all  do          Test  Test new  browser    end    Test element present  should    nil   If your the element is NOT present  your spec will pass  but if the element is present   it will throw an error  test failed

Try this  Call this method and pass 3 arguments    WebDriver variable      assuming driver variable as driver  The element which you are going to check  Should provide from By method     ex  By id  id   Time limit in seconds    Example  waitForElementPresent driver  By id  id    10     public static WebElement waitForElementPresent WebDriver driver  final By by  int timeOutInSeconds             WebElement element            try              driver manage   timeouts   implicitlyWait 0  TimeUnit SECONDS     nullify implicitlyWait                 WebDriverWait wait   new WebDriverWait driver  timeOutInSeconds                element   wait until ExpectedConditions presenceOfElementLocated by                 driver manage   timeouts   implicitlyWait 10  TimeUnit SECONDS     reset implicitlyWait             return element    return the element           catch  Exception e                e printStackTrace                       return null

I had the same issue  For me  depending on a user s permission level  some links  buttons and other elements will not show on the page  Part of my suite was testing that the elements that SHOULD be missing  are missing  I spent hours trying to figure this out  I finally found the perfect solution    What this does  is tells the browser to look for any and all elements based specified  If it results in 0  that means no elements based on the specification was found  Then i have the code execute an if statement to let me know it was not found   This is in C   so translations would need to be done to Java  But shouldnt be too hard   public void verifyPermission string link        IList lt IWebElement gt  adminPermissions   driver FindElements By CssSelector link        if  adminPermissions Count    0                Console WriteLine  User s permission properly hidden              There s also another path you can take depending on what you need for your test   The following snippet is checking to see if a very specific element exists on the page  Depending on the element s existence I have the test execute an if else    If the element exists and is displayed on the page  I have console write let me know and move on  If the element in question exists  I cannot execute the test I needed  which is the main reasoning behind needing to set this up   If the element Does Not exists  and is not displayed on the page  I have the else in the if else execute the test   IList lt IWebElement gt  deviceNotFound   driver FindElements By CssSelector  CSS LINK GOES HERE       if the element specified above results in more than 0 elements and is displayed on page execute the following  otherwise execute whats in the else statement if  deviceNotFound Count  gt  0  amp  amp  deviceNotFound 0  Displayed         script to execute if element is found   else         Test script goes here      I know I m a little late on the response to the OP  Hopefully this helps someone

What about a private method that simply looks for the element and determines if it is present like this   private boolean existsElement String id        try           driver findElement By id id          catch  NoSuchElementException e            return false            return true      This would be quite easy and does the job   Edit  you could even go further and take a By elementLocator as parameter  eliminating problems if you want to find the element by something other than id

You can try implicit wait    WebDriver driver   new FirefoxDriver    driver Manage   Timeouts   ImplicitlyWait TimeSpan FromSeconds 10    driver Url    http   somedomain url that delays loading   IWebElement myDynamicElement   driver FindElement By Id  someDynamicElement       Or You can try explicit wait one    IWebDriver driver   new FirefoxDriver    driver Url    http   somedomain url that delays loading   WebDriverWait wait   new WebDriverWait driver  TimeSpan FromSeconds 10    IWebElement myDynamicElement   wait Until lt IWebElement gt   d    gt                return d FindElement By Id  someDynamicElement               Explicit will check if element is present before some action  Implicit wait could be call in every place in the code  For example after some AJAX actions   More you can find at SeleniumHQ page
