I was trying to submit a form without button using just Capybara and Rspec

capybara_form_submit.rb

class Capybara::Session
  def submit(element)
    Capybara::RackTest::Form.new(driver, element.native).submit({})
  end
end

#in the test
fill_in 'Search', with: 'dice'

form = find '#search-form' # find the form
page.submit form           # use the new .submit method, pass form as the argument

This is awesome! I looked at both suggestions. Thanks!

I already have

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

in my spec/rails_helper.rb for other reasons, so I created a new file spec/support/submit_form.rb:

def submit_form(form_selector)
  form = find("form#{form_selector}")
  Capybara::RackTest::Form.new(page.driver, form.native).submit({})
end

Now my tests allow me to call things like:

submit_form '#my_form_id'
submit_form '.my_form_class'
