使用带有Capybara和Rspec的设计测试Rails应用程序不会导致方法错误

Question

我刚刚开始在我的Rails应用程序上进行一些测试，其中我使用了design进行身份验证。我刚刚生成了rspec，只添加了

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end

到我的规格/支持/设计。rb文件。我还将Capybara添加到gemfile中的测试组中，运行bundle命令，等等。但是当我在测试中访问时，我得到了一个no method错误。下面是我的user_spec.rb:

的一个例子

require 'spec_helper'
describe "Club" do
  before(:each) do
    @club ||= FactoryGirl.create(:club)
    FactoryGirl.create(:membership)
    User.all.each{|x| x.delete}
  end
  describe "privacy" do
    it "shouldn't be shown any tournament if the user is private" do
      attributes = FactoryGirl.attributes_for(:user)
      user = User.create!({private: true}.merge(attributes))
      assert(user.private)
      visit "/user/#{user.id}/tournaments"
      page.should have_no_selector(".tournament-list")
    end
  end
end

当我运行rspec时，出现如下错误:

Failures:
  1) Club privacy shouldn't be shown any tournament if the user is private
     Failure/Error: visit "/user/#{user.id}/tournaments"
     NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_3::Nested_1:0x007ff0ea113108>
     # ./spec/user_spec.rb:14:in `block (3 levels) in <top (required)>'

Answer 1

对于capybara规格，我使用:

describe "Club", :type => :feature, :js => true do
  include Capybara::DSL
  it "..."
end

而不是User.all。每个{|x| x.d eet}，使用DatabaseCleaner

Answer 2

您可以轻松地将Capybara::DSL添加到RSpec config spec_helper中。rb

RSpec.configure do |config|
  .....
  .......
  config.include(Capybara::DSL)
end
