私たちのコントローラが、私たちが持っているparamに基づいて与えられた回数だけクラスを呼び出していることをテストしようとしていますが、rspecでテストが失敗しています。クラスはゼロを返す。ruby Class.new rspecでnilを返しています
class ProcessFaxesController < ApplicationController
def create
email = params["From"]
attachment_count = params["attachment-count"].to_i
head :ok
if attachment_count > 0
attachment_count.times do |document_index|
FaxedDocumentProcessor.new(params, document_index+1).perform
end
else
DocumentProcessingMailer.delay.failure_notification(email, "No attachment found.")
end
end
end
外部クラス：：これは、我々は我々のテストから取得しているエラーがある
require 'rails_helper'
RSpec.describe ProcessFaxesController, type: :controller do
context "#create" do
context 'with attachments' do
before { allow_any_instance_of(FaxedDocumentProcessor).to receive(:perform).and_return(true) }
it 'calls the FaxedDocumentProcessor attachment-count times' do
expect(FaxedDocumentProcessor).to receive(:new).twice
post :create, 'email' => '[email protected]', 'attachment-count' => 2)
end
end
end
end
：このスペックで
class FaxedDocumentProcessor
def initialize(params, document_index)
@params = params
@attachment = @params["attachment-#{document_index}"]
@email = @params['From']
end
def perform
# some stuff here
end
end
私たちは、このコントローラーを持っています

binding.pryをコントローラメソッドに挿入しようとしましたが、呼び出しを試みるたびにエラーは発生しません。
FaxedDocumentProcessor.newには何も返されない可能性がありますか？なぜ私たちはエラーを再現できないのですか？
あなたの質問は不明です。あなたのコードには 'Class.new'の呼び出しはありません。これは 'Class.new'と何が関係していますか？クラスを動的に生成しているわけではありません。 –
