Question

我有一个生成新用户的rake任务。需要通过命令行输入email，password和password_confirmation（confirm）的值。

这是我的佣金任务代码：

namespace :db do
  namespace :setup do
    desc "Create Admin User"
    task :admin => :environment do
      ui       = HighLine.new      
      email    = ui.ask("Email: ")
      password = ui.ask("Enter password: ") { |q| q.echo = false }
      confirm  = ui.ask("Confirm password: ") { |q| q.echo = false }

      user = User.new(email: email, password: password,
                  password_confirmation: confirm)
      if user.save
        puts "User account created."
      else
        puts
        puts "Problem creating user account:"
        puts user.errors.full_messages
      end
    end
  end
end

我可以通过从命令行输入“rake db：setup：admin”来调用它。

现在我想用rspec测试这个任务。到目前为止，我设法创建了以下规范文件：

require 'spec_helper'
require 'rake'

describe "rake task setup:admin" do 
  before do
    load File.expand_path("../../../lib/tasks/setup.rake", __FILE__)
    Rake::Task.define_task(:environment)
  end

  let :run_rake_task do 
    Rake.application["db:setup:admin"]
  end

  it "creates a new User" do
    run_rake_task
  end
end

在运行规范时，我的rake任务将从命令行请求输入。所以我需要的是解析电子邮件，密码和确认的值，以便在执行我的规范时，rake任务不会要求这些字段的值。

如何从spec文件中实现此目的？

你可以找出HighLine：

describe "rake task setup:admin" do
  let(:highline){ double(:highline) }
  let(:email){ "test@example.com" }
  let(:password){ "password" }

  before do
    load File.expand_path("../../../lib/tasks/setup.rake", __FILE__)
    Rake::Task.define_task(:environment)
    allow(HighlLine).to receive(:new).and_return(highline)
    allow(highline).to receive(:ask).with("Email: ").and_return(email)
    allow(highline).to receive(:ask).with("Enter password: ").and_return(password)
    allow(highline).to receive(:ask).with("Confirm password: ").and_return(password)
  end

  let :run_rake_task do
    Rake.application["db:setup:admin"]
  end

  it "creates a new User" do
    run_rake_task
  end
end
