Question

我正在使用Rails进行RSpec测试，由于我分配给模型关联的命名空间模型，它失败了。

CLI：

Failures:

1) Blog::BlobsController GET index assigns all blog/blobs as @blobs
 Failure/Error: expect(assigns(:blog::blobs)).to eq([blog::blobs])
 NoMethodError:
   undefined method `blobs' for :blog:Symbol
 # ./spec/controllers/blog/blobs_controller_spec.rb:8:in `block (3 levels) in <top (required)>'

规格/控制器/博客/ blobs_controller_spec.rb

RSpec.describe Blog::BlobsController, type: :controller do
  describe "GET index" do
    it "assigns all blog/blobs as @blobs" do
      blobs = Blog::Blob.create!
      get :index, {}
      expect(assigns(:blog::blobs)).to eq([blog::blobs])
    end
  end
end

的routes.rb

# SNIPPED FOR BREVITY...
namespace :blog do
  resources :blobs
end

应用/控制器/博客/ blobs_controller.rb

class Blog::BlobsController < ApplicationController
  before_filter :authenticate_user!, except: [:index, :show]


  def index
    @blobs = Blog::Blob.all
  end

  def new
    @blob = Blog::Blob.new
  end

  def edit
    @blob = Blog::Blob.find(params[:id])
  end

  def create
    @blob = Blog::Blob.new(blob_params)

    if @blob.save
      redirect_to @blob
    else
      render 'new'
    end
  end

  def update
    @blob = Blog::Blob.find(params[:id])

    if @blob.update(blob_params)
      redirect_to @blob
    else
      render 'edit'
    end
  end

  def show
    @blob = Blog::Blob.find(params[:id])
  end

  def destroy
    @blob = Blog::Blob.find(params[:id])
    @blob.destroy!

    redirect_to blog_blobs_path
  end

  private
    def blob_params
      params.require(:blob).permit(:title, :body)
    end
end

使用RSpec测试此控制器有更好的方法吗？

更新了规范代码：

require 'rails_helper'

RSpec.describe Blog::BlobsController, type: :controller do
  describe "GET #index" do
    it "assigns all blobs as @blobs" do
      blob = Blog::Blob.create!
      get :index, {}
      expect(assigns(:blobs)).to eq([blob])
    end
  end
end

你的测试说：

blobs = Blog::Blob.create!

这很令人困惑，因为blobs是复数，但你只创建了一个blob。首先将其重命名为blob。然后expect(assigns(:blog::blobs)).to eq([blog::blobs])应为expect(assigns(:blobs)).to eq([blob])。

在索引操作中，您设置@blobs = Blog::Blob.all。赋值对应于控制器的实例变量。没有命名空间。

RSpec在分配给博客的命名空间模型上失败
