오이 비동기 자바 스크립트 오류

Question

composings/index.html.erb의 "save"버튼을 누를 때마다 ajax 요청이 완료되고 동일한 페이지에 Composition.content 문자열을 표시하는 행이 추가됩니다. 그러나 내 오이 테스트에서 오류가 표시됩니다.

Feature: User creates compositions 

    Scenario: User creates a composition             # features/composition.feature:2 
    Given I go to the compositions page             # features/step_definitions/composition_steps.rb:1

    When I press "Save"                 # features/step_definitions/composition_steps.rb:9

추가 된 행이 아직 그 지점에서 렌더링되지 않았기 때문에 오류가 발생 했습니까? 제발 좀 대답 해줘. 감사!

Answer 1

When /^(?:|I)fill in "([^\"]*)" with "([^\"]*)"$/ do |field, value| 
fill_in(field, :with => value) 
end 

When /^(?:|I)press "([^\"]*)"$/ do |button| 
click_button(button) 
end 

Then /^I should see "([^"]*)" within "([^"]*)"$/ do |text, selector| 
    find(:xpath, "//#{selector}[contains(text(),'#{text}')]").should_not(be_nil, "Could not find the text '#{text}' within the selector '#{selector}'") 
end 

Then /^I should see "(.*?)" added in the compositions page$/ do |text| 
    page.should have_content(text) 
end
