日志显示"重定向"，但 RSpec 看到'success'

Question

我有一个规格:

it "should redirect to the log_books_controller#new action when a user logs in who owns zero LogBooks" do    
  visit '/auth/facebook'
  response.should redirect_to new_log_book_path
end

失败，出现以下错误:

1) LogBooksController should redirect to the log_books_controller#new action when a user logs in who owns zero LogBooks
     Failure/Error: response.should redirect_to new_log_book_path
       Expected response to be a <:redirect>, but was <200>.
     # ./spec/controllers/log_books_controller_spec.rb:7

但是根据我的log/test.log文件，实际上有一个重定向。我遗漏了什么吗?我觉得这个规范应该过时了。

log/test.log file:

Started GET "/auth/facebook/callback" for 127.0.0.1 at Thu Nov 24 10:24:01 -0600 2011
  Processing by SessionsController#create as HTML
  Parameters: {"provider"=>"facebook"}

   (0.1ms)  SELECT 1 FROM "users" WHERE ("users"."uid" = '1234' AND "users"."provider" = 'facebook') LIMIT 1
  SQL (1.3ms)  INSERT INTO "users" ("created_at", "name", "nickname", "provider", "uid", "updated_at") VALUES (?, ?, ?, ?, ?, ?)

   (0.1ms)  SELECT COUNT(*) FROM "log_books" WHERE "log_books"."user_id" = 17
Redirected to http://rpglogger.com/log_books/new
Completed 302 Found in 35ms

我还尝试在visit '/auth/facebook'行之后添加调试器行，并且在规范response.code返回:成功，所以我看到测试失败的原因，但我不知道的是为什么当日志清楚地显示重定向时，响应设置为:success。

我的猜测是Capybara遵循重定向并获取302响应中位置指定的页面，该响应生成200状态码。

您可以通过在重定向位置测试页面内容来处理此问题，或者使用带有rack-test的控制器规范而不是Capybara。
