【问题描述】：

使用 httparty 通过 json 帖子创建用户会创建用户（如服务器日志所示），但测试在这两种情况下均失败。用户计数未更改或未找到用户。这是我对测试、规范或 rspec 处理创建数据库记录的方式的理解的问题吗？

结果：

  1) User signup and signin with native request with valid information should save the user
     Failure/Error: User.where(email: "bigbadwolf@example.com").should exist
       expected #<ActiveRecord::Relation []> to exist

  1) User signup and signin with native request with valid information should save the user
     Failure/Error: expect {
       result should have been changed by 1, but was changed by 0

规格：

describe "User", :type => :api do
  describe 'signup and signin' do 
  .
  .
   context "with native request" do
     context "with valid information" do
       it "should save the user" do 
        expect {
        response2 = HTTParty.post('http://localhost:3000/api/v1/registrations.json', 
        :body => { :user => 
          {
          :username => "bigbadwolf",
          :email => "bigbadwolf@example.com",
          :password => "mywolfie", 
          :password_confirmation => "mywolfie"
          } }.to_json,
       :headers => { 'Content-Type' => 'application/json', 'ClientType' => 'native', 'Accept' => 'application/json' })
       }.to change{User.count}.by(1) 
       User.where(email: "bigbadwolf@example.com").should exist
       .
       .
      end  
    end
    end
  end
end

日志：

(2.0ms)  BEGIN
  User Exists (1.0ms)  SELECT 1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER('bigbadwolf@example.com') LIMIT 1
  User Exists (1.0ms)  SELECT 1 AS one FROM "users" WHERE "users"."username" = 'bigbadwolf' LIMIT 1
  SQL (1.0ms)  INSERT INTO "users" ("created_at", "email", "password_digest", "updated_at", "username") VALUES ($1, $2, $3, $4, $5) RETURN

【问题讨论】：

你能分享问题中失败的例子吗？
您是否有理由不使用 post 能力中的工厂或 RSpecs 构建？你可以做post "/login", :username => "jdoe", :password => "secret"等
这会包括自定义标题吗？我正在使用 httparty，所以我可以添加自定义标头。

【解决方案1】：

Rspec 将数据保存到开发数据库而不是测试。我需要配置测试模式。

强制 rspec 使用测试数据库。

# spec_helper.rb
ENV["RAILS_ENV"] = 'test'

以测试模式运行服务器。

rails s -e test
