Handle common Selenium Exceptions effectively

📌 NoSuchElementException

Solution: Before interacting with any element, ensure that the element is present on the DOM. You can use explicit waits (WebDriverWait) with ExpectedConditions to wait for the presence of the element before proceeding with any action.

📌 StaleElementReferenceException

Solution: This exception occurs when the referenced element becomes stale or invalid. To avoid this, refresh the page or re-find the element before interacting with it.

📌 TimeoutException

Solution: Increase the wait time using explicit waits if the page or element takes longer to load than expected.

📌 ElementClickInterceptedException

Solution: This exception occurs when another element is covering the target element. You can try scrolling to the element or using JavaScript click to interact with the element directly.

📌 ElementNotInteractableException

Solution: Ensure the element is visible and not obscured by other elements. You can use JavaScript to make the element visible or move to it before interacting with it.

📌 ElementNotSelectableException

Solution: Make sure the element is a selectable element, such as checkboxes or options within a dropdown. Verify that the element is interactable using the is_displayed() or is_enabled() methods.

📌 ElementNotVisibleException

Solution: If an element is not visible, try scrolling to the element or check if it's hidden within an iframe. Ensure the visibility of the element using explicit waits and ExpectedConditions.

📌 ErrorInResponseException

Solution: This exception usually indicates a server-side error. Review your test case and check the server logs to identify the root cause of the error.

📌 NoSuchFrameException

Solution: Double-check the frame name or index before switching to it. Ensure that the frame exists before attempting to switch.

📌 NoSuchWindowException

Solution: Verify the window handle before attempting to switch to it. Ensure that the window still exists.

📌 RemoteDriverServerException

Solution: Ensure that the browser capabilities are correctly set when initializing the WebDriver. Review the capabilities and make necessary adjustments to match the browser and its version.

📌 ScreenshotException

Solution: This exception may occur when the driver is unable to take a screenshot due to various reasons. Ensure that the driver has sufficient permissions to access the system resources for capturing screenshots.

📌 SessionNotCreatedException

Solution: Review the browser version, driver version, and browser capabilities to ensure compatibility. Additionally, check if any browser-specific configurations or extensions are interfering with the session creation.

📌 StaleElementReferenceException

Solution: If you suspect that an element might become stale, try to minimize interactions with it once it's located. If an action triggers a page reload, re-find the element afterwards to avoid the stale reference.

📌 InvalidSessionIdException

Solution: This exception typically occurs when a session has expired or is no longer valid. Ensure that you are managing your sessions properly and not attempting to use an invalid session ID.

📌 JavascriptException

Solution: Review the JavaScript code that is being executed and ensure its correctness. Check for any errors or syntax issues in the JavaScript code itself.

📌 NoSuchCookieException

Solution: Before attempting to access a cookie, verify that the cookie exists for the current browsing context. You can use the get_cookies() method to retrieve the list of cookies and check if the desired cookie is present.

📌 InvalidArgumentException

Solution: Double-check the arguments you're passing to WebDriver commands. Ensure that the data types and formats are correct. If necessary, validate the input data before using it in the WebDriver command.

📌 NoSuchAttributeException

Solution: Before trying to retrieve an attribute, make sure the element exists and the attribute you're trying to access is valid for that element. Verify the attribute name and the element's existence before accessing the attribute.

📌 NoSuchElementException

Solution: Apart from explicit waits, consider using implicit waits at the WebDriver level to wait for elements to be present. Be cautious with implicit waits as they can slow down your test execution if used excessively.

📌 TimeoutException

Solution: Along with increasing wait times, consider implementing a retry mechanism for certain actions that are prone to timeouts. This can help mitigate occasional delays and timeouts caused by network fluctuations.

📌 WebDriverException

Solution: Regularly update your WebDriver and browser versions to the latest stable releases. This can help resolve compatibility issues and leverage the latest features and improvements.

📌 InvalidSelectorException

Solution: Validate your CSS selectors and XPath expressions before using them to locate elements. Consider using browser developer tools to test selectors interactively.

📌 ElementNotInteractableException

Solution: If you're having consistent issues interacting with an element, consider discussing with the development team to improve the accessibility and user-friendliness of the application.

📌 ElementNotVisibleException

Solution: If an element is not visible due to being outside the viewport, consider scrolling to it using WebDriver's execute_script method. Ensure the element's visibility before interacting with it.
