Quality Assurance Introduction to Selenium Test Drive Selenium Locating by ID

Is it ever okay to locate by ID's?

I just wanted to be clear on something.

I understand it's bad practice to create an ID element simply so we can grab it using Selenium, but is it ever okay to select an element with a prexisting id like Craig did?

It seems a shame not to be able to use the method if we know we can :)

I wouldn't agree that it's always bad practice to use ID's. I think it's entirely appropriate if you know there will only ever be one item on the page that serves a particular purpose.

I believe the general rule about using classes instead of ID is intended primarily for styling, though even there it might still be appropriate if you're certain that only one element will ever receive a particular style.

Yeah by all means if the ID exists use it, but don't go making them yourself ;)
