如何更改Xcode 4用于下载组件的Apple ID？(How can I change the Apple ID that Xcode 4 uses to download components?)

 除非是一个流程，否则我不会在一个场景中这样做。 我不会去xyz.com，我也不会点击，因为那不是'行为。 页面对象将帮助您。 
 
Scenario: Register a new account
Given I do not have an account
When I register a new account
Then I can use those credentials to access the site
 
 然后我会创建适当的步骤 
 
Given(/^I do not have an account%/) do
  @credentials = get_unique_credentials
  @browser = Watir::Browser.new :firefox
end

When(/^I register a new account$/) do
  visit RegistrationPage do |page|
    page.name = @credentials[0]
    page.password = @credentials[1]
    page.register
  end
end

Then(/^I can use those credentials to access the site$/) do
  visit LoginPage do |page|
    page.name = @credentials[0]
    page.password = @credentials[1]
    page.login
  end
  on HomePage do |page|
    expect(page.something).to exist
  end
end

I would not do that in one scenario unless it is one flow. And I wouldn't go to xyz.com, and I wouldn't click on things because that isn't 'behavior. Page objects will help you.
