Rspec测试CSV文件下载 [英] Rspec test CSV file download

问题描述

我想确保我的 CSV 下载包含正确的列.当我使用 RSpec 测试 CSV 下载时，我无法访问文件内容.如何访问 CSV 文件的内容?

I want to make sure my CSV download contain the correct columns. When I test a CSV download with RSpec I cannot access the file contents. How do I access the contents of the CSV file?

require 'spec_helper'
include Devise::TestHelpers

describe Admin::ApplicationsController do

  before(:each) do
    @application = FactoryGirl.create :application
    @user = FactoryGirl.create( :admin_user )
    sign_in @user
  end

  it "downloads a csv"
  it "gives us only the columns we want" do
    get :index, format: :csv
    p response.body
    p response.headers
  end
end

测试结果:

# This is the output in the terminal
# ""
# {"Content-Type"=>"text/csv; charset=utf-8", "Content-Disposition"=>"attachment; filename=\"applications-2013-12-17.csv\""}

推荐答案

在你的描述块调用 render_views 如下:

At your describe block call render_views as in:

describe Admin::ApplicationsController do
  render_views
  ... # all the other code
end

调用 render_views 指示 RSpec 在控制器规范中渲染视图内容.默认情况下这是关闭的，因为当您运行控制器规范时，您通常不关心视图内容，这会使您的测试运行得更快.

Calling render_views instructs RSpec to render the view contents inside a controller spec. This is turned off by default because when you're running controller specs you usually don't care about the view contents and this makes your tests run faster.
