Question

我正在使用shoulda-callback-matchers gem测试回调。 Rails版本是5.2.2，RSpec版本是3.8.0。

任何人都知道如何使用after_create_commit gem测试shoulda-callback-matchers回调吗？

它适用于after_create和after_update。

型号代码

after_create :admission_created_notification
after_update :admission_status_change_notification

示例示例

context "callbacks" do
 let(:admission) { create(:admission) }
   it { expect(admission).to callback(:admission_created_notification).after(:create) }
   it { expect(admission).to callback(:admission_status_change_notification).after(:update) }
end

Answer 1

类似这样的东西：

RSpec.describe YourModel, type: :model do
  context 'callbacks check' do
    it { is_expected.to callback(:admission_created_notification).after(:create) }
    it { is_expected.to callback(:admission_status_change_notification).after(:update) }
  end
end

Answer 2

我没有使用上述宝石。我使用Rspec的默认方式为这些回调编写rspec。 模型回调代码

class Admission < ApplicationRecord
  after_create_commit :admission_created_notification
  after_update_commit :admission_status_change_notification
end

型号规格代码

context 'create and update' do
    let(:student_detail) { FactoryBot.create(:student_detail) }
    let(:institute_program) { FactoryBot.create(:institute_program) }
    let(:admission) { FactoryBot.create(:admission, student_detail: student_detail, institute_program: institute_program) }
    it 'When create' do
      admission.student_detail.notifications.count(1)
      admission.institute_program.institute_detail.notifications.count(1)
    end
    it 'When applied' do
      admission.update(status: 'applied')
      admission.student_detail.notifications.count(2)
      admission.institute_program.institute_detail.notifications.count(2)
    end
    it 'When accepted' do
      admission.update(status: 'accepted')
      admission.student_detail.notifications.count(3)
      admission.institute_program.institute_detail.notifications.count(3)
    end
    it 'When rejected' do
      admission.update(status: 'rejected')
      admission.student_detail.notifications.count(3)
    end
    it 'When approved' do
      admission.update(status: 'approved')
      admission.student_detail.notifications.count(4)
      admission.institute_program.institute_detail.notifications.count(4)
      admission.notifications.count(9)
    end
  end

使用shoulda-callback-matchers` gem + rails 5 + rspec测试after_create_commit回调
