i usually couple of methods  in pair  for verification whether element is present or not   public boolean isElementPresent By locatorKey        try           driver findElement locatorKey           return true        catch  org openqa selenium NoSuchElementException e            return false           public boolean isElementVisible String cssLocator       return driver findElement By cssSelector cssLocator   isDisplayed        Note that sometimes selenium can find elements in DOM but they can be invisible  consequently selenium will not be able to interact with them  So in this case method checking for visibility helps   If you want to wait for the element until it appears the best solution i found is to use fluent wait   public WebElement fluentWait final By locator       Wait lt WebDriver gt  wait   new FluentWait lt WebDriver gt  driver               withTimeout 30  TimeUnit SECONDS               pollingEvery 5  TimeUnit SECONDS               ignoring NoSuchElementException class        WebElement foo   wait until new Function lt WebDriver  WebElement gt              public WebElement apply WebDriver driver                return driver findElement locator                          return foo       Hope this helps

Instead of doing findElement  do findElements and check the length of the returned elements is 0  This is how I m doing using WebdriverJS and I expect the same will work in Java

Unable to comment to The Meteor Test Manual  since I have no rep  but I wanted to provide an example that took me quite awhile to figure out   Assert assertEquals 0  wd findElements By locator  locator    size       This assertion verifies that there are no matching elements in the DOM and returns the value of Zero  so the assertion passes when the element is not present   Also it would fail if it was present

Use findElements instead of findElement   findElements will return an empty list if no matching elements are found instead of an exception  Also  we can make sure that the element is present or not   Ex    List elements     driver findElements By yourlocatorstrategy    if elements size   gt 0       do this      else       do that
