方法定义的Rspec验证 - 失败/错误

Question

在Rspec中，测试一个实例是否能够调用方法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 

目前得到以下错误信息：

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)>' 

我很期待对于T他将Docking_spec.rb中的@dockstat实例化，以响应DockingStation.rb中定义的release_bike方法，但事实并非如此。
