Selenium -- How to wait until page is completely loaded

Question

I am trying to automate some test cases using Java and Selenium WebDriver  I have the following scenario    There is a page named  Products   When I click on  View Details  link in the  Product  page  a popup  modal-dialog  containing the details of the item appears  When I click on the  Close  button in the popup the popup closes and the page automatically refreshes  the page is just reloading  the contents remain unchanged   After closing the popup I need to click on  Add Item  button in the same page  But when WebDriver trying to find the  Add Item  button  if the internet speed is too fast  WebDriver can find and click the element  But if the internet is slow  WebDriver finds the button before the page refresh  but as soon as the WebDriver click on the button  the page refreshes and StaleElementReferenceException occurs  Even if different waits are used  all the wait conditions become true  since the contents in the page are same before and after reload  even before the page is reloaded and StaleElementReferenceException occurs    The test case works fine if Thread sleep 3000   is used before clicking on the  Add Item  button  Is there any other workaround for this problem

You can do this in many ways before clicking on add items:

WebDriverWait wait = new WebDriverWait(driver, 40);
wait.until(ExpectedConditions.elementToBeClickable(By.id("urelementid")));// instead of id u can use cssSelector or xpath of ur element.


or

wait.until(ExpectedConditions.visibilityOfElementLocated("urelement"));

You can also wait like this. If you want to wait until invisible of previous page element:

wait.until(ExpectedConditions.invisibilityOfElementLocated("urelement"));

Here is the link where you can find all the Selenium WebDriver APIs that can be used for wait and its documentation.

It seems that you need to wait for the page to be reloaded before clicking on the  Add  button  In this case you could wait for the  Add Item  element to become stale before clicking on the reloaded element   WebDriverWait wait   new WebDriverWait driver  20   By addItem   By xpath    input    Add Item          get the  Add Item  element WebElement element   wait until ExpectedConditions presenceOfElementLocated addItem       trigger the reaload of the page driver findElement By id         click        wait the element  Add Item  to become stale wait until ExpectedConditions stalenessOf element        click on  Add Item  once the page is reloaded wait until ExpectedConditions presenceOfElementLocated addItem   click

3 answers  which you can combine    Set implicit wait immediately after creating the web driver instance        driver Manage   Timeouts   ImplicitWait   This will try to wait until the page is fully loaded on every page navigation or page reload  After page navigation  call JavaScript return document readyState until  complete  is returned  The web driver instance can serve as JavaScript executor  Sample code   C   new WebDriverWait driver  MyDefaultTimeout  Until  d   gt    IJavaScriptExecutor  d  ExecuteScript  return document readyState   Equals  complete       Java  new WebDriverWait firefoxDriver  pageLoadTimeout  until        webDriver - gt    JavascriptExecutor  webDriver  executeScript  return document readyState   equals  complete      Check if the URL matches the pattern you expect

yes stale element error is thrown when  taking your scenario  you have defined locator strategy to click on  Add Item  first and then when you close the pop up the page gets refreshed hence the reference defined for  Add Item  is lost in the memory so to overcome this you have to redefine the locator strategy for  Add Item  again  understand it with a dummy code      clicking on view details  driver findElement By id      click       closing the pop up  driver findElement By id      click         and when you try to click on Add Item driver findElement By id      click       you get stale element exception as reference to add item is lost     so to overcome this you have to re identify the locator strategy for add item     Please note   this is one of the way to overcome stale element exception      Step 1 please add a universal wait in your script like below  driver manage   timeouts   implicitlyWait 20  TimeUnit SECONDS      just after you have initiated browser

There are two different ways to use delay in selenium one which is most commonly in use  Please try this    driver manage   timeouts   implicitlyWait 20  TimeUnit SECONDS    second one which you can use that is simply try catch method by using that method  you can get your desire result if you want example code feel free to contact me defiantly I will provide related code
