Capybara, checking HTML element by ID and Class

Question

Two questions from a beginner.

Q1- Is it possible to assert the existence of an HTML node by ID and class? For example, to see if the following element exists:

Answer 1

You can combine the selectors.

For your first question, the following checks for a div with id "first" and class "drawer":

page.should have_css('div#first.drawer')

For your second question, the within block can use the same css-selector as above:

within('div#first.drawer') do

Or if you really prefer xpath, you can do:

within("//div[@id='first' and @class='drawer']") do
