Ruby on rails 使用Rspec和Rails进行转换后的测试

我有两种型号：LessonBooking和CustomerRequests

一旦支付了LessonBooking，关联的CustomerRequests将被标记为booked。注意：LessonBooking不通过id直接关联，但客户在付款时会输入他们的电子邮件，此电子邮件用于检查现有的客户请求，如果发现这些请求，则会标记为booked。以下是第_booking.rb课中的相关代码：

event :payment_received do
  transition :form_started => :paid
end
after_transition :form_started => :paid do |booking|
  email = booking.teaching_relationship.student.account.email
  customer_request = CustomerRequest.find_by_email(email)
  unless customer_request.nil?
    customer_request.book
  end
end

CustomerRequest模型本身也有一个状态机，它有一个事件簿作为 如图所示：

event :book do
  transition [:new, :opened, :awaiting_response] => :booked
end

现在，我无法通过一个测试LessonBooking从form_开始到paid的过渡以及CustomerRequest从new到booked的后续过渡的规范

以下是我编写的规范：

context 'when there is an associated customer request' do
  before :each do
    @student = create(:student)
    relationship = create(:teaching_relationship, student: @student)
    @new_booking = create(:lesson_booking, teaching_relationship: relationship)
    @customer_request = create(:customer_request, student: @student, email: @student.account.email )
  end

  it "it changes the state of the customer request" do
    @new_booking.payment_received
    expect(@customer_request.state).to eq 'booked'
  end
end

结束

我的测试总是失败，请注意：

expected: "booked"
got: "new"

我知道一般的测试，我会感谢任何帮助。

将其抽象为一个方法，检查是否收到，然后在isolationok中测试该方法，所以你的意思是我应该在转换后为代码编写一个方法：form\u开始：paid，对吗？如果是这样，我将如何检查/测试它是否被接收？类似于：转换后：form\u start=>：paid，do:：method\u name
