how to check span class by capybara

Question

How to check how many <span class=error>error text</span> is on page?

The code below is not working:

should have_selector('span.error', :count => 5)

Answer 1

From the docs:

all('a').each { |a| a[:href] }

So something like the following should be possible:

all('span.error').count.should == 5
