Question

我有一个带有简单:after_update回调的模型，由于某种原因该回调没有触发。我进行了一项测试，检查该函数是否已调用并通过，但是由于某种原因，实际上没有任何反应。

class HealthProfile < ApplicationRecord

    after_update :send_office_email

    def send_office_email
        p "sending office email"
        email = MailjetService.new(ID)

        Rails.application.routes.default_url_options[:host] = 'host_name'

        message = email.send_email('email', self.location.email, "New Health Profile: #{self.name}", {
            "office_name" => self.location.name,
            "name" => self.name,
            "url" => Rails.application.routes.url_helpers.health_profile_url(self)
        })

        p message
    end
end

测试：

require 'rails_helper'

RSpec.describe HealthProfile, type: :model do

    before(:each) do
        @hp = build(:health_profile)
    end

    it 'emails office on update (complete - w/ signature)' do
        p 1
        @hp.save
        p 2
        expect(@hp).to receive(:send_office_email)
        p "updating signature to true..."
        @hp.update(signature: 't')
        p 3
    end
end

在测试输出中，我看到以下内容：

1
2
"updating signature to true..."
3

但是我从没见过sending office email。测试通过，表明该模型已收到回调，但该回调中没有任何内容运行。我想念什么？

实际上，我相信您的测试正在正常进行。如果不是，则您的测试会因expected to receive "send_office_email" but nothing was called而失败。

expect to_receive在对象上添加了方法，导致生成的伪方法不会调用您的原始方法。

尝试一下。

require 'rails_helper'

RSpec.describe HealthProfile, type: :model do

    let(:hp) { build(:health_profile) }

    it 'emails office on update (complete - w/ signature)' do
        p 1
        hp.save
        p 2
        p "updating signature to true..."
        hp.update(signature: 't')
        p 3
    end
end

回调不被呼叫，即使它应该
