我目前正在尝试学习黄瓜以及如何正确使用黄瓜.在搜索最佳实践时,描述了大多数旧方法,我还没有真正找到一个好的指南.
我读到了关于这种方法的新方法,但我对最佳实践存在一些问题.

以下是我一直在研究的一些基本黄瓜方案.

Scenario: Unsuccessful login
    Given a user has an account
    When the user tries to log in with invalid information
    Then the user should see an log in error message

Scenario: Successful login
   Given a user has an account
   When the user logs in
   Then the user should see an log in success message
   And the user should see a sign out link

Scenario: Successful logout
   Given a signed in user
   Then the user logs out
   And the user should see an log out success message

我想知道这是否可以？我有问题,如果我应该把它写成“我访问”或“用户访问”或“他访问”基本上什么是首选？

其次,我想知道我应该如何制定以下内容：

Scenario: Visit profile of user
  Given a user
  And a second user
  When the user visit the user profile
  Then the user should see the name of the user

Scenario: Visit profile of another user
  Given a user
  And a second user
  When the user visit the second users profile
  Then the user should see the name of the second user

这只是我放在一起的东西,但我觉得这不是最好的方法.
我在步骤定义文件中遇到问题.您将如何定义处理方案的步骤？我想写一些更通用的东西,但也许它真的不可能？我应该有@second_user属性还是你建议的？

def user
  @user ||= FactoryGirl.create :user
end

Given /^a signed in user$/ do
  user
  sign_in(@user.email,@user.password)
end

Given /^a user has an account$/ do
  user
end


When /^the user logs in$/ do
  sign_in(@user.email,@user.password)
end

When /^the user logs out$/ do
  click_link ('Sign out')
end

When /^the user tries to log in with invalid information$/ do
  sign_in("incorrect-email","incorrect-password")
end

Then /^the user should see a sign out link$/ do
  page.should have_link('Sign out')
end

Then /^the user should see an log in success message$/ do
  should have_success_message('Signed in successfully.')
end

When /^the user should see an log out success message$/ do
  should have_success_message('Signed out successfully.')
end

Then /^the user should see an log in error message$/ do
  should have_error_message('Invalid email or password.')
end

谢谢你的协助！

解决方法

I have problems if I should write it as “I visit” or “the user visit” or “he visit” Basically what is preferred?

我认为使用“当用户访问时”这样的内容会更通用,并且更具可读性,因为您不必继续思考“谁是’他’？”如果您正在阅读测试,那么真正重要的是您在所有文件中坚持一些约定,这样您就不会感到困惑.

关于创建@second_user的第二个问题,我认为你不应该这样做,因为这个用户并不完全是你的场景的一部分,因为它是一个数据设置,我认为处理数据设置的最好方法是使用pickle with cucumber,它基本上允许你在你的黄瓜中创建模型,而不必将它们作为变量保存,有一个great cast on RailsCast可以解释很多.

所以我会用泡菜做这个

Scenario: Visit profile of another user
  Given a user exists with name: "Mike",username: "mike"
  And a signed in user
  When the user visits the profile of "mike"
  Then the user should see 'Mike'

然后你可以定义

When /^the user visits the profile of (.+)$/ do |username|
  visit("/#{username}") # I am assuming here usernames are unique and the profile url is "/:username"
end
