How to wait until an element no longer exists in Selenium
I don't know why but ExpectedConditions.invisibilityOf(element)
is the only work for me while ExpectedConditions.invisibilityOfElementLocated(By)
, !ExpectedConditions.presenceOfElementLocated(By)
... not. Try it!
Hope this help!
Why don't you simply find the size of elements
. We know the the collection of elements' size would be 0 if element does not exist.
if(driver.findElements(By.id("foo").size() > 0 ){
//It should fail
}else{
//pass
}
You can also use -
new WebDriverWait(driver, 10).until(ExpectedConditions.invisibilityOfElementLocated(locator));
If you go through the source of it you can see that both NoSuchElementException
and staleElementReferenceException
are handled.
/**
* An expectation for checking that an element is either invisible or not
* present on the DOM.
*
* @param locator used to find the element
*/
public static ExpectedCondition<Boolean> invisibilityOfElementLocated(
final By locator) {
return new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
try {
return !(findElement(locator, driver).isDisplayed());
} catch (NoSuchElementException e) {
// Returns true because the element is not present in DOM. The
// try block checks if the element is present but is invisible.
return true;
} catch (StaleElementReferenceException e) {
// Returns true because stale element reference implies that element
// is no longer visible.
return true;
}
}
The solution would still rely on exception-handling. And this is pretty much ok, even standard Expected Conditions rely on exceptions being thrown by findElement()
.
The idea is to create a custom Expected Condition:
public static ExpectedCondition<Boolean> absenceOfElementLocated(
final By locator) {
return new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
try {
driver.findElement(locator);
return false;
} catch (NoSuchElementException e) {
return true;
} catch (StaleElementReferenceException e) {
return true;
}
}
@Override
public String toString() {
return "element to not being present: " + locator;
}
};
}
