i am testing on a trading platform. one of the tabs is a profile page. on the profile page, there is a link to "change password", and i want to test if that works, using selenium IDE. The problem i am running into is that if the user can change their password, and the test passed, when rerun, i will have have error as the password will already exist. i know i need to use random values using javascirpt but i am not too sure how. any help and demonstration with any website will be very appreciated. I ma very new to selenium.
