Ruby-on-rails – How to test an image src and alt value using capybara

Capybara uses xpath by default, so unless you changed that setting, that could be part of your problem. (You could use locate(:css, "img[alt]")).

I would write the tests using xpath to look something like this:

Then /^I should see the alt text "([^\"]*)"$/ do | alt_text |
    page.should have_xpath("//img[@alt=#{alt_text}]")
end

Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id|
    page.should have_xpath("//input[@id=#{input_id} and text()=#{input_value}]
end

I found the following worked for me:

# Check
find(:css, "#cityID[value='62']").set(true)

# Uncheck
find(:css, "#cityID[value='62']").set(false)
