Question

在这个环境中，是否还有人在运行黄瓜测试时遇到麻烦？

错误

我不知道该怎么做。

Answer 1

我遇到了同样的问题，我的所有“步骤”都通过了，但由于ActiveRecord与数据库清理程序的混合，我的方案失败了。

 Scenario: User is not signed up                               # features/users/sign_in.feature:6
    Given I am not logged in                                    # features/step_definitions/user_steps.rb:86
    And no user exists with an email of "user@invalidemail.com" # features/step_definitions/user_steps.rb:1
    When I go to the sign in page                               # features/step_definitions/web_steps.rb:48
    And I sign in as "user@invalidemail.com/please"             # features/step_definitions/user_steps.rb:61
    Then I should see "Invalid email or password."              # features/step_definitions/web_steps.rb:105
    And I go to the home page                                   # features/step_definitions/web_steps.rb:48
    And I should be signed out                                  # features/step_definitions/user_steps.rb:81

Failing Scenarios:
cucumber features/users/sign_in.feature:6 # Scenario: User is not signed up

1 scenario (1 failed)
7 steps (7 passed)

我在执行黄瓜测试时得到了一些提示：

$bundle exec cucumber --verbose features/users/sign_in.feature:15

WARNING: You have set Rails' config.cache_classes to false (most likely in config/environments/cucumber.rb).

奇怪的是，它在前一步骤中没有失败。

spec_helper.rb

RSpec.configure do |config|
    # == Mock Framework
    config.mock_with :rspec    

    config.before(:suite) do
      DatabaseCleaner.strategy = :truncation
      DatabaseCleaner.clean_with(:truncation)
      ...
    end

    ...
    config.before(:each) do
      DatabaseCleaner.start
    end

    config.after(:each) do
      DatabaseCleaner.clean
    end
...
end

End
begin
  DatabaseCleaner.strategy = :truncation, { :except => %w[oauth_tokens client_applications] }
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end

Answer 2

我不得不删除DatebaseCleaner

rails 3.1.3 / cucumber / database_cleaner / mongo_mapper
