Org.openqa selenium.nosuchelementexception
I am currently engaged in a particular task that is related to automating a test case for a web-based application by using the Selenium WebDriver. The application has a dynamic page where there are certain elements loaded asynchronously. For this, I have written a script that can attempt to interact with one of these dynamic elements. However, during the execution, I encountered an Issue which is stating that “org.openqa selenium.nosuchelementexception”. How can I troubleshoot and resolve this particular issue?
In the context of selenium, here are the troubleshooting steps and reasons given:-
Reasons
This particular issue can be raised due to the following reasons:-
Incorrect locator
The locator which you are using might be incorrect or outdated.
Element not present in the DOM
It is very much possible that the element is not possible in the DOM at that time the search when the search is attempted.
Timing issues
The element might not be available when the search is performed. This is one of the most common reasons for this particular issue.
Iframe or frames
The element can be inside an iframe or frame which requires switching to the frame before infarction with the element.
Solutions:-
Current locator
You should try to ensure that the locater used is correct or not. You can use the tools like browser developer tools to verify the locator.
Explicit wait
You can implement an explicit wait to wait for the element to be presented or visible before interacting with it.
Switch to Iframes
If the element is inside an iframe, then you can switch the WebDriver context to that iframe before trying to find the element.
visibility checking
You should check if the element is visible by using a method such as “isDisplay()” before trying to interact with it.
Here is an example given below of how you can use a java based example which demonstrates how you can handle this particular issue by using the explicit waits in selenium WebDriver. In this example we would wait for an element to become visible before interacting with it:-
Import org.openqa.selenium.By;
Import org.openqa.selenium.WebDriver;
Import org.openqa.selenium.WebElement;
Import org.openqa.selenium.chrome.ChromeDriver;
Import org.openqa.selenium.support.ui.ExpectedConditions;
Import org.openqa.selenium.support.ui.WebDriverWait;
Public class NoSuchElementExceptionExample {
Public static void main(String[] args) {
// Set the path to your ChromeDriver executable
System.setProperty(“webdriver.chrome.driver”, “path/to/chromedriver.exe”);
WebDriver driver = new ChromeDriver();
Try {
// Navigate to a web page
Driver.get(https://example.com);
// Create an explicit wait with a timeout of 10 seconds
WebDriverWait wait = new WebDriverWait(driver, 10);
// Wait for the element to be present in the DOM
WebElement dynamicElement = wait.until(ExpectedConditions.presenceOfElementLocated(By.id(“dynamicElementId”)));
// Wait for the element to be visible
WebElement visibleElement = wait.until(ExpectedConditions.visibilityOf(dynamicElement));
// Now you can interact with the visible element
visibleElement.click();
// Other actions on the page…
} catch (org.openqa.selenium.NoSuchElementException e) {
// Handle the exception (e.g., log an error message)
System.err.println(“Element not found: “ + e.getMessage());
} catch (org.openqa.selenium.TimeoutException e) {
// Handle the case where the element is not found within the time limit
System.err.println(“Timeout waiting for element: “ + e.getMessage());
} finally {
// Close the browser
Driver.quit();
}
}
}
