Selenium not finding element
Solution 1
Is this a timing issue? Is the element (or the whole page) AJAX-loaded? It's possible that it's not present on the page when you're trying to look for it, WebDriver is often "too fast".
To solve it, is either implicit or explicit wait.
The Implicit Wait way. Because of the implicit wait set, this will try to wait for the element to appear on the page if it is not present right away (which is the case of asynchronous requests) until it times out and throws as usual:
// Sooner, usually right after your driver instance is created.
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
// Your method, unchanged.
@Test
public void Appointments() {
...
driver.findElement(By.id("ctl00_Header1_liAppointmentDiary")).doSomethingWithIt();
...
}
The Explicit Wait way. This will only wait for this one element to be present on the page when looking for it. Using the ExpectedConditions
class, you can wait for different things, too - the element to be visible, clickable etc.:
import static org.openqa.selenium.support.ui.ExpectedConditions.*;
@Test
public void Appointments() {
...
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(presenceOfElementLocated(By.id("ctl00_Header1_liAppointmentDiary")))
.doSomethingwithIt();
...
}
Solution 2
You're searching for ctl00_Header1_liAppointmentDiary
, but there only is Header1_liAppointmentDiary
, those are not the same...
ctl00_Header1_liAppointmentDiary != Header1_liAppointmentDiary
Solution 3
There is no element with id="ctl00_Header1_liAppointmentDiary"
in your html
driver.findElement(By.id("ctl00_Header1_liAppointmentDiary"));
Should be
driver.findElement(By.id("Header1_liAppointmentDiary"));

I don't understand why this code doesn't find the element on the page. The website doesn't use iframes.
@Test public void Appointments() { driver.findElement(By.id("ctl00_Header1_liAppointmentDiary")); }
this is the error message I get:
FAILED: Appointments org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"id","selector":"ctl00_Header1_liAppointmentDiary"}

Hoyesic almost 11 yearsI tried that as well but I get the same error message. I've tried using findElement by xpath, but I get the same error

Petr Janeček almost 11 yearsIf it only were invisible, the element would still get found. It would not throw a
NoSuchElementException
. When you'd then try to interact with the element, it would throwElementNotVisibleException
. -
Mr_Dave almost 5 yearsI would expect the same, but I've just encountered this exact situation today as well. The element is not detected until I scroll down the page, making it visible.
