That's exactly right!

defined function?

(TL;DR: user defined)

It completely depends on the subject of your test, so you'll have to know a
little about the object you're dealing with in each case. For browser
tests, you're usually dealing with some kind of PageObject element, so
you'll want to reference the API documentation for PageObject
<http://rubydoc.info/github/cheezy/page-object/> and WebDriver
<http://watir.github.io/watir-webdriver/doc/>. (Zeljko might know of some
API documentation that's easier to follow.) Alternatively, just try it and
if you get a NoMethodError, the object doesn't respond to `visible?`.

Hope this helps!
