启动测试后出现Rspec错误

Question

我试着开始我的rspec测试，然后

RAILS_ENV=test bundle exec rspec

我:

我谷歌了一下，但没有找到解决方案。我注意到rspec只在模型上工作得很好，但是当我想在控制器上启动它时，我得到了同样的错误。

Answer 1

没有ENV也是一样的。我的reports_controller_spec。rb:

require 'rails_helper'
RSpec.describe ReportsController do
  let(:user) { create :user }
  before { sign_in user }
  describe 'GET #subjects' do
    subject { get :subjects }
    it_behaves_like 'template rendering action', :subjects
  end
end

我是规范测试的新手，我没有看到错误。这是reports_controller.rb。也许会有帮助。

class ReportsController < ApplicationController
  expose(:subject_items) { SubjectItem.includes(:teacher, :students) }
end
