方法定義的Rspec驗證 - 失敗/錯誤

Question

在Rspec中，測試一個實例是否能夠調用方法x。

DockingStation.rb

class DockingStation 
    def release_bike 
    end 
end 

Docking_spec.rb

require_relative '../lib/DockingStation' 

describe DockingStation do 
    before(:each) do 
    @dockstat = DockingStation.new 
    end 

describe "#DockingStation" do 
    it "Check release method" do 
    expect(@dockstat).to respond_to(:release_bike) 
    end 
end 

end 

目前得到以下錯誤信息：

1) DockingStation#DockingStation Check release method 
    Failure/Error: expect(@dockstat).to respond_to(:release_bike) 
     expected #<DockingStation:0x007fa518a6da00> to respond to :release_bike 
    # ./spec/Docking_spec.rb:10:in `block (3 levels) in <top (required)>' 

我很期待對於T他將Docking_spec.rb中的@dockstat實例化，以響應DockingStation.rb中定義的release_bike方法，但事實並非如此。
