更新到軌道5規格後失敗的ActionController ::參數

Question

我更新導軌5.0.1，並得到了失敗規範

該規範是

describe "POST create", :vcr do 
    let(:subscription) { mock_model(Subscription).as_null_object } 
    before do 
     allow(Subscription).to receive(:new).and_return(subscription) 
    end 

    it "creates a new Subscription" do 
     expect(Subscription).to receive(:new). 
     with("card_expiration" => "a quick brown fox"). 
     and_return(subscription) 
     post :create, params: { :subscription => { "card_expiration" => "a quick brown fox" }} 
    end 
end 

它失敗

如何獲取ActionController :: Parameters到期望值？

Answer 1

你必須改變期望，期望實際的ActionController ::參數對象，像這樣：

parameters = ActionController::Parameters.new(
     "card_expiration" => "a quick brown fox").permit! 

expect(Subscription).to receive(:new). 
     with(parameters). 
     and_return(subscription)
