ruby-on-rails - 如何在 ruby​​-on-rails 中测试破坏失败

问题描述

每个人。

我要测试一个活动记录对象销毁失败，但我在创建失败情况时遇到了问题。

我有一个名为“ require_user_payment_info ”的before_filter方法，它在调用delete方法之前验证@payment_info对象，因此在调用delete方法之前我无法创建“坏” @payment_info对象。

这是require_user_payment_info方法：

def require_user_payment_info 
  @payment_info = credit_card_model.slave.find_by_user_guid(user_guid)
  if !@payment_info || @payment_info.user_guid != user_guid
    redirect_to(:controller => 'store', :action => 'index') and return false
  else
    if((@payment_info.card_expires_year.to_i < Date.today.year) || 
        ((@payment_info.card_expires_month.to_i < Date.today.month) && (@payment_info.card_expires_year.to_i == Date.today.year)))        
      @payment_info.card_account_public = "" #clear this out so the user is forced to re-enter the credit card number
      @payment_info.valid?        
      flash.now[:error] = t('ui_flash_errors.card_expired_error')
    end
  end
end

而实际的删除方法：

def delete
  # required to be called via a delete request
  redirect_to :action => 'edit' and return if !request.delete?
  if @payment_info.destroy
    flash[:notice] = "Delete SUCCESSFUL"
    redirect_to :action => 'new'
  else
    flash[:error] = "Delete failed"
    redirect_to :action => 'edit'
  end

有任何想法吗？

解决方案

这是我的解决方案：

def test_delete
    payment_info = Factory.create(:payment_info, :user_guid=>@user.guid, :card_expires_month=>'04', 
                                    :card_expires_year=>(Date.today.year+2).to_s, :cardholder_city=>"test city",
                                      :cardholder_state=>'NC', :cardholder_country=>'US', :cardholder_zip=>'27612')
    PaymentInfo.any_instance.stubs(:destroy).returns(false)

    delete(:delete, {}, @session)
    assert_response(:redirect)
    assert_equal false, assigns(:payment_info).blank?
    assert_redirected_to({:controller=>'account', :action=>'edit'})
    assert_equal flash[:error], "There was an error deleting your credit card information. Please try again."
end
