Question

我有以下内容：

class PaymentController < ActionController::API
  include ObjectActions

  def error_notification(message)
    puts "An error has occurred: #{message}"
  end
end

module ObjectActions
  extend ActiveSupport::Concern

  def process
    if valid?
      # process payment
    else
      error_notification("Payment is not valid")
    end
  end
end

现在，我试图模仿/存储＆＃34;外部＆＃34; error_notification模块/关注中的ObjectActions方法。

RSpec.describe ObjectActions, type: :concern do
  include ObjectActions

  before do
    allow(described_class).to receive(:valid?).and_return(false)

    # I KNOW THIS IS NOT RIGHT, HOW CAN I PROPERLY MOCK IT?
    allow(described_class).to receive(:error_notification).and_return("Blah blah")
  end

  context '#process' do
    it { expect { process }.to eq("Blah blah") }
  end
end

Answer 1

简短回答是

allow(self).to receive(:error_notification).and_return("Blah blah")

为什么？

您要包含该模块，您想在当前测试中进行测试

RSpec.describe ObjectActions, type: :concern do
  include ObjectActions

所以这就是你应该嘲笑的。但这是一个更好的方法，我在不久前在这个答案中描述了这一点：https://stackoverflow.com/a/48914463/299774

RSpec如何模拟控制器方法内部关注？
