Answer from AI
Exceptions when working with Selenium occur for various reasons related to interaction with the web page and browser:
- NoSuchElementException: when the script tries to access an element that does not exist on the page.
- ElementNotInteractableException: the element exists but is not available for interaction (e.g., hidden or blocked).
- TimeoutException: when waiting for an element or event exceeds the specified time.
- StaleElementReferenceException: the element was found, but the page has been refreshed, and the reference to the element is outdated.
- WebDriverException: general errors related to the browser driver or its state.
Reasons for occurrence:
- Asynchronous loading of the page or elements.
- DOM changes during test execution.
- Incorrect locators or script errors.
- Browser or driver issues.
To reduce the number of exceptions, it is recommended to use explicit waits and check the state of elements before interaction.
