Question

如何存根此属性？

user.rb

def my_method
  scheduling_frequency_minutes = self.business.settings_group.scheduling_frequency.minutes
  # where scheduling_frequency is an integer field in the settings_group model
  # but this is still set to the default (60), not 30
end

user_spec.rb

it "get available time slots (on the half hour)" do

  # 1st attempt:
  @business.settings_group.scheduling_frequency = 30
  # where @business is the same Business pointed to by 'self.business' in the user.rb model

  # 2nd attempt:
  #Business.stub_chain(:settings_group, :scheduling_frequency).and_return(30)

  #3rd attempt:

  settings_group = mock("settings_group")
  settings_group.stub(:scheduling_frequency).and_return(30)
  @business.should_receive(:settings_group).and_return(settings_group)

  @business.users.all.first.my_method
end

更新

这是我的最新尝试，但仍然无法运作。发生了什么？

user = @business.users.all.first
user.stub_chain(:business, :settings_group, :scheduling_frequency).and_return(30)
user.my_method()

-

  def my_method
    debugger
    # p self.business.settings_group.scheduling_frequency -> 60
  end

您需要在整个方式和正确的上下文中链接（在本例中为用户）

user = User.new
user.stub_chain(:business, :settings_group, :scheduling_frequency).and_return(30)
user.my_method

我尝试了以下独立版本并且有效。（我在rails之外做了这个，所以分钟方法不可用。）

require 'rspec'

class User
  def my_method
    scheduling_frequency_minutes = self.business.settings_group.scheduling_frequency
  end
end

describe User do
  it "get available time slots (on the half hour)" do
    user = User.new
    user.stub_chain(:business, :settings_group, :scheduling_frequency).and_return(30)
    user.my_method.should eql(30)
  end

end
