You can try this code to let the page load completely until element is found   public void waitForBrowserToLoadCompletely         String state   null      String oldstate   null      try           System out print  Waiting for browser loading to complete             int i   0          while  i  lt  5                Thread sleep 1000               state     JavascriptExecutor  driver  executeScript  return document readyState    toString                System out print       Character toUpperCase state charAt 0                       if  state equals  interactive      state equals  loading                    break                                If browser in  complete  state since last X seconds  Return                               if  i    1  amp  amp  state equals  complete                      System out println                    return                            i                      i   0          oldstate   null          Thread sleep 2000                          Now wait for state to become complete                     while  true                state     JavascriptExecutor  driver  executeScript  return document readyState    toString                System out print       state charAt 0                      if  state equals  complete                    break               if  state equals oldstate                   i                else                 i   0                                If browser state is same  loading interactive  since last 60                secs  Refresh the page                              if  i    15  amp  amp  state equals  loading                      System out println   nBrowser in     state     state since last 60 secs  So refreshing browser                     driver navigate   refresh                    System out print  Waiting for browser loading to complete                    i   0                else if  i    6  amp  amp  state equals  interactive                      System out println                            nBrowser in     state     state since last 30 secs  So starting with execution                     return                             Thread sleep 4000               oldstate   state                     System out println           catch  InterruptedException ie            ie printStackTrace

You can use the below existing method to set the time for pageeLoadTimeout  in below example if the page is taking more than 20 seconds to load   then it will throw an exception of page reload    WebDriver driver   new FirefoxDriver    driver manage   timeouts   pageLoadTimeout 20  TimeUnit SECONDS

If you want to wait for a specific element to load  you can use the isDisplayed   method on a RenderedWebElement       Sleep until the div we want is visible or 5 seconds is over long end   System currentTimeMillis     5000  while  System currentTimeMillis    lt  end           Browsers which render content  such as Firefox and IE  return  RenderedWebElements      RenderedWebElement resultsDiv    RenderedWebElement  driver findElement By className  gac m             If results have been returned  the results are displayed in a drop down      if  resultsDiv isDisplayed            break             Example from The 5 Minute Getting Started Guide

I m surprised that predicates weren t the first choice as you typically know what element s  you will next interact with on the page you re waiting to load  My approach has always been to build out predicates functions like waitForElementByID String id  and waitForElemetVisibleByClass String className   etc  and then use and reuse these wherever I need them  be it for a page load or page content change I m waiting on   For example   In my test class   driverWait until textIsPresent  expectedText      In my test class parent   protected Predicate lt WebDriver gt  textIsPresent String text       final String t   text      return new Predicate lt WebDriver gt             public boolean apply WebDriver driver               return isTextPresent t                       protected boolean isTextPresent String text       return driver getPageSource   contains text       Though this seems like a lot  it takes care of checking repeatedly for you and the interval for how often to check can be set along with the ultimate wait time before timing out  Also  you will reuse such methods   In this example  the parent class defined and initiated the WebDriver driver and the WebDriverWait driverWait   I hope this helps

For implicit wait you can use something like following   driver manage   timeouts   implicitlyWait 10  TimeUnit SECONDS    In order for webpage to wait for a specific object to be visible or cerntain condition to be true  You can use wait feather of web driver     120 is maximum number of seconds to wait  WebDriverWait wait   new WebDriverWait driver 120     wait until ExpectedConditions elementToBeClickable  CONDITITON       In Java  another option is to sleep the thread for specific time    Thread sleep numberOfSeconds 1000      This line will cause thread to sleep for seconds as variable   I created a method to simplify thread sleep method  public static void wait time int seconds       try           Thread sleep seconds 1000            catch  InterruptedException e               TODO Auto-generated catch block             e printStackTrace                  Use the method as wait time 10    The thread will sleep for 10 seconds

All of these solutions are OK for specific cases  but they suffer from at least one of a couple of possible problems    They are not generic enough -- they want you to know  ahead of time  that some specific condition will be true of the page you are going to  eg some element will be displayed  They are open to a race condition where you use an element that is actually present on the old page as well as the new page    Here s my attempt at a generic solution that avoids this problem  in Python    First  a generic  wait  function  use a WebDriverWait if you like  I find them ugly    def wait for condition function       start time   time time       while time time    lt  start time   3          if condition function                return True         else              time sleep 0 1      raise Exception  Timeout waiting for     format condition function   name       Next  the solution relies on the fact that selenium records an  internal  id-number for all elements on a page  including the top-level  lt html gt  element   When a page refreshes or loads  it gets a new html element with a new ID   So  assuming you want to click on a link with text  my link  for example   old page   browser find element by tag name  html    browser find element by link text  my link   click    def page has loaded        new page   browser find element by tag name  html       return new page id    old page id  wait for page has loaded    For more Pythonic  reusable  generic helper  you can make a context manager   from contextlib import contextmanager   contextmanager def wait for page load browser       old page   browser find element by tag name  html        yield      def page has loaded            new page   browser find element by tag name  html           return new page id    old page id      wait for page has loaded    And then you can use it on pretty much any selenium interaction   with wait for page load browser       browser find element by link text  my link   click     I reckon that s bulletproof   What do you think     More info in a blog post about it here

The easiest way is just wait for some element which will appear on loaded page   If you would like to click on some button already after page is loaded you could use await and click   await   until   at most 20  TimeUnit Seconds  some element isDisplayed       or another condition getDriver   find some element  click

This seems to be a serious limitation of WebDriver  Obviously waiting for an element will not imply the page being loaded  in particular the DOM can be fully build  onready state  whereby JS is still executing and CSS and images are still loading   I believe the simplest solution is to set a JS variable upon the onload event after everything is initialized and check and wait for this JS variable in Selenium

You can explicitly wait for an element to show up on the webpage before you can take any action  like element click     driver get  http   somedomain url that delays loading    WebElement myDynamicElement    new WebDriverWait driver  10      until new ExpectedCondition lt WebElement gt              Override         public WebElement apply WebDriver d            return d findElement By id  myDynamicElement            This is what I used for a similar scenario and it works fine
