Question

在关注http://guides.rubyonrails.org/testing.html并尝试对我自动生成的控制器运行测试时，这是我所面临的错误。

控制器和控制器的测试文件都是自动生成的。仅强制title字段对模型进行了更改。

不确定我错过了什么。 rails服务器是否需要启动并运行才能运行功能测试？

Answer 1

我的坏。一旦我将环境变量RAILS_ENV从development切换到test，所有测试都会通过。

Answer 2

尝试将session[:_csrf_token] = SecureRandom.base64(32)添加到before do块，然后查看测试是否通过。

运行Rails 4和MiniTest中生成的功能测试时出现InvalidAuthenticityToken错误
