我正在使用 Cucumber 和 Capybara/rack_test 测试 rails 应用程序。我有以下步骤定义：
Then /^I should see '([^']*)'$/ do |content|
visit about_path
response.should have_content(content)
end
about_path映射到哪里/about。
每次我的故事都因信息而失败
Feature: Some Great Feature
So that I can blah-blah
As a Blah-blah
I want blah-blah
Scenario: Show project label on about page # features/about.feature:7
Given I'm on '/about' page # features/step_definitions/about_steps.rb:1
Then I should see 'About' # features/step_definitions/about_steps.rb:5
expected there to be content "About" in "" (RSpec::Expectations::ExpectationNotMetError)
./features/step_definitions/about_steps.rb:7:in `/^I should see '([^']*)'$/'
features/about.feature:9:in `Then I should see 'About''
Failing Scenarios:
cucumber features/about.feature:7 # Scenario: Show project label on about page
1 scenario (1 failed)
2 steps (1 failed, 1 passed)
请注意，实际内容为空。我尝试过的每条路径都是空的。
这很奇怪，因为 rspecs 通过了。
有什么我可以尝试的吗？如果您需要更多信息，请告诉我。
