为什么我为Cucumber :: Rails :: World获取未定义的方法`click'？ 在Cucumber / Capybara的步骤

Question

I can get other capybara methods like visit, fill_in, select etc.. to work. but not click

Given /^a no fee license called "([^"]*)"$/ do |arg1|
  @l = FactoryGirl.create(:license,
                      name: arg1)
end

When /^execute the license$/ do
  visit(license_path(@l))
  click('Execute License')
end

error:

Scenario: no fee license is executed                                 # features/visitor_no_fee_license.feature:14
    When I fill out the licensee info with valid info                  # features/step_definitions/licenses_steps.rb:21
    And execute the license                                            # features/step_definitions/licenses_steps.rb:35

Answer 1

Capybara's DSL changed. Use click_on instead of click, if you don't know if it's a link or a button now.

Perhaps you meant to use click_link ?

When /^(?:|I )follow "([^"]*)"$/ do |link|
  click_link(link)
end

There is also click_button

If neither of these suit your needs, then you can call click on an element.

When /^(?:|I )click "([^"]*)" span$/ do |selector|
  element ||= find('span', :text => selector)
  element.click
end

If none of the above is helpful, then here are a list of all the click methods, if you identify the one you wish to use, I may be able to assist further.
