在不触发电子邮件的情况下测试模型回调

Question

我有一个Rails 5应用程序，正在我的模型中测试回调。我希望确保回调被调用，但我不想实际触发以下行，因为它调用API并发送电子邮件：

response = bird.request(body, employee.location.birdeye)

我的测试如下：

it 'expects to send request through birdeye if valid' do
    req = build(:review_request)
    expect(req).to receive(:send_request)
    req.save
end

这行得通，但是上面提到的这行被触发了。如何在不触发对bird.request()的调用的情况下测试此回调？这是我的模型：

class ReviewRequest < ApplicationRecord
  belongs_to :user
  belongs_to :review, optional: true
  belongs_to :employee, optional: true

  after_create :send_request

  def client
    self.user.client
  end

  def send_request
    p "send_request callback..."
    ap self
    ap client
    body = {
        name: client.try(:name),
        emailId: user.email,
        phone: client.try(:phone),
        employees: [
            {
                emailId: employee.try(:email)
            }
        ]
    }

    bird = Birdeye.new
    response = bird.request(body, employee.location.birdeye)

    ap body
    return response
  end
end

Answer 1

如果您只想检查回调是否被调用，那么我认为模拟send_request可能是可行的。请尝试以下操作

before do
  allow_any_instance_of(ReviewRequest).to receive(:send_request).and_return(true)
end

it 'expects to call :send request after creating a ReviewRequest' do
    allow_any_instance_of(ReviewRequest).to receive(:send_request)
    create(:review_request)
end

如果您想测试send_request的实现，那么可以使用存根Birdeye
