Capybara: Quick checking for element presence (without retries or timeout)
Element finding is a central feature of Capybara. Since
#find is normally used to get elements from the current page and interact with them, it's a good thing that some Capybara drivers (e.g. Selenium) will wait an amount of time until the expected element shows up. But if Capybara cannot
#find it at all, you'll get an error.
if page.find('.that-element') # Do something else # Never happens because #find raises end
In order to simply check whether an element is present, without errors raised, you can use
#has_css?. It will return a Boolean – but will wait as well. If the element does not exist, it will take the configured
Capybara.default_wait_time for this check to return
false, which is usually several seconds.
The solution is to disable the waiting for just that check:
if page.has_css?('.that-element', wait: 0) # Do something else # Do something else end
wait: 0 argument. Actually there is
worth knowing (scroll down to the "Options Hash" section).
