Selenium error: no such element: Unable to locate element on .isDisplayed() method

I have an if statement below which is getting me an issue. If certain selections are made in a different dropdown, the page displays a second dropdown and a check box. The below code works as expected when a selection is made that causes those two elements to display but it doesn't if a selection is made that doesn't make them display. I get the no such element: Unable to locate element error. At first I thought it was returning true either way but the issue is it's crashing because. I even added a check at trying to assign the value to a booolean but still get the same error.

boolean dropdown = driver.findElement(By.id("DROPDOWN")).isDisplayed(); gets the same error.

      if(driver.findElement(By.id("DROPDOWN")).isDisplayed()){

                driver.findElement(By.id("DROPDOWN")).click();
                driver.findElement(By.xpath("Choice in Drop DOWN)).click();
                driver.findElement(By.id("CheckBox")).click();  
     }

This has to do with element being present in DOM verses element being visible at UI. Instead, you should use findElements. As when you save a list and then use the condition to make sure it is among that list of found elements or not, it will not produce the hard exception error.

List<WebElement> ele=driver.findElements(by.xpath"abcd///abcd");
              if(ele.size()== 0){
                 // empty list if no matching element
                 System.out.println("Element not present, appearing "+ele.size()+ " time");
              } else {
                 System.out.println("Element present, appearing "+ele.size()+ " time");

}

isDisplayed() will work if the element is present in the DOM, followed by the style attribute :- display should not be false or none.

If prior action is a selection which led both the element to be displayed, it means the element is in the DOM but that wont be visible. So checking the visibility condition would return u false.

Try waiting for the element to get visible and perform the check operation on it which would reduce the sync latency.

WebDriverWait wait = new WebDriverWait(WebDriverRunner.getWebDriver(),5); wait.until(ExpectedConditions.visibilityOfElementLocated("By Locator"));

if (dropdown.isDisplayed()) 

   `````````// If the dropdown is tagged with <Select> tag
   ``````````` Select dropDown = new Select(dropdown);
    ```````````dropDown .selectByValue("value);

  ```````` // Else fetch the dropdown list item and store it in a list and iterate through and perform the desired action
    ```````````List<WebElement> dropDownList = new ArrayList<Webelements>;
    ```````````dropDownList.forEach(element -> {
        ```````````if(element.getText().equals("value")){
           ``````` ````element.click();
       ``````````` }
   ``````````` });

    ```````````driver.findElement(By.id("CheckBox")).click(); 
}

The following answers explain how to handle checking an element exists and handle the exception by wrapping in a custom method.

How to check if Element exists in c# Selenium drivers

I would also recommend re-writing your code as the following to avoid duplication and avoid xpath selectors. Using findElement twice for in the same context is not necessary just create a variable.

var dropdown = driver.findElement(By.id("DROPDOWN"));
if (dropdown.Displayed()) 
{
    var selectElement = new SelectElement(dropdown);
    selectElement.SelectByValue("valuehere");
}

If you are using the text rather than the value in the select box you can use SelectByText("texthere"); instead of SelectByValue.

findElement method will throw this hard exception - No such element if the element is not found. Just include Exception Handling for No Such Element and your logic should work just fine.

try{
if(driver.findElement(By.id("DROPDOWN")).isDisplayed()){

                driver.findElement(By.id("DROPDOWN")).click();
                driver.findElement(By.xpath("Choice in Drop DOWN)).click();
                driver.findElement(By.id("CheckBox")).click();  
     }
catch (NoSuchElementException e)
{
// I believe you dont have to do anything here. May be a console log will do.
}
