使用capybara,如何使用page.should render_template

Question

我有以下测试:

  it "I can Sign Up with Facebook" do

    visit new_user_registration_path

    click_link_or_button 'Sign up with Facebook'

    # Validate
    page.should render_template("registrations/signup_connect_to_facebook.html.erb")

  end

在日志中,我得到:

Started GET "/users/auth/facebook/callback" for 127.0.0.1 at 2011-08-30 13:26:04 -0700
  Processing by AuthenticationsController#create as HTML
  Authentication Load (0.8ms)  SELECT "authentications".* FROM "authentications" WHERE "authentications"."provider" = 'facebook' AND "authentications"."uuid" = '13' LIMIT 1
AuthenticationsController - Route D
Rendered registrations/signup_connect_to_facebook.html.erb (0.7ms)
Completed 200 OK in 111ms (Views: 3.4ms | ActiveRecord: 2.7ms)
  SQL (0.3ms)  ROLLBACK

问题是测试失败:

 1) authentication flows I can Sign Up with Facebook
     Failure/Error: page.should render_template("registrations/signup_connect_to_facebook.html.erb")
     ArgumentError:
       @request must be an ActionDispatch::Request
     # ./spec/requests/authentication_requests.rb:54:in `block (2 levels) in <top (required)>'

Finished in 1.11 seconds
1 example, 1 failure

验证模板的正确方法是什么？谢谢

我认为你遇到的问题是你正在混合测试水平.

如果要测试模板的渲染,请尝试执行正常的rspec控制器测试.

对于Capybara,您应该断言渲染模板的结果而不是模板的实际渲染.
