有一个公司类has_many QuarterValue,我有一个RSpec测试.
- let(:company) { Company.create }
- describe 'company has many quarter values' do
- before do
- 10.times { create(:quarter_value,company: company) }
- end
- it 'has 10 quarter values' do
- expect(company.quarter_values.count).to eq(10)
- end
- end
测试通过我的问题是当我将binding.pry放在expect matcher上方时,我无法访问company.quarter_values,返回空数组[].
如何使用binding.pry在RSpec测试中访问has_many模型对象？
投机/ factories.rb
- FactoryGirl.define do
- factory :company do
- sequence(:code) { |n| n + 1000 }
- end
- factory :quarter_value do
- company
- end
- end
解决方法
您需要修改代码,如下所示：
- let(:company) { Company.create }
- describe 'company has many quarter values' do
- before do
- 10.times { create(:quarter_value,company: company) }
- company.reload
- end
- it 'has 10 quarter values' do
- expect(company.quarter_values.count).to eq(10)
- end
- end
您在开始创建的公司变量不知道它已经被赋予了任何quarter_value.您需要调用company.reload来更新公司,因为该公司模型的实例没有涉及到create(：quarter_value,company：company)
