19. How would you handle an exception in selenium? code example
Example 1: exceptions in selenium
-> NoSuchElementException:
Once I get this exception I usually check
#1- Locator: most likely might be a locator issue
or
#2- Synchronization : Is my driver is running parallel to my browser.
or
#3- Iframe : There might be iframe to switch to
----> StaleElementException (reference not fresh anymore)
- We need to refresh the reference of the web element throwing this exception.
- Page Object Design pattern solves this problem.
- POM Design pattern will do something called a "freshness" check for
the web element being used.
- What is freshness check: re-locating web element with given locator
everytime we use.
---> TimeOutException
-I get this exception only when you use explicit wait (WebDriverWait)
-If explicit condition (element to be clickable) is not met, selenium
will throw this exception.
-> ElementNotVisible
-> ElementNotInteractable
-> ElementNotClickable
