describe CategoriesController do
    login_user

    it "redirect when something went wrong" do
      get :index
      expect(response).to render_template("index")
    end
end

给我：

1）当出现问题时，CategoriesController重定向
失败/错误：期望（响应）.to render_template（“index”）
期待＆lt;“index”＆gt;但使用＆lt; []＆gt;

进行渲染

Answer 1

首先，检查一下，如果您的操作按预期工作，请添加一些输出作为最后一行并查看是否已打印。然后，如果要像这样测试模板渲染，则应使用render_views

require 'rails_helper'

describe CategoriesController do
  render_views
  login_user

  it "redirect when something went wrong" do
    get :index
    expect(response).to render_template("index")
  end
end

期待＆lt;＆＃34; index＆＃34;＆gt;但使用＆lt; []＆gt;进行渲染
