Need to assert that there is no such element in the webpage,
When tried with fieldValueBox.isDisplayed();
instead of "false" its throwing "NoSuchElementFound" exception.
Right now i was using 'try catch' and making decision in 'catch'
If the element is not on the page, then you will get 'NoSuchElementFound' exception. You can try checking that the number of elements with the locator is zero:
private boolean elementNotOnPage(){
boolean elementIsNotOnPage = false;
List<WebElement> element = driver.findElements(yourLocator);
if(element.size() == 0){
elementIsNotOnPage = true;
}
return elementIsNotOnPage;
}
