有没有人在运行这个环境中的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，我所有的“步骤”都通过了，但由于ActiveRecord与数据库清理器混合，我的方案失败。

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

Failing Scenarios:

我正在执行我的黄瓜测试时，什么可能是一个暗示：

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

奇怪的是它并不失败在Before步骤。

     DatabaseCleaner.start

    config.after(:each) do
