Question

class Crud 

$people = { } 

def self.add 

    puts "Enter the name of the person you would like to add in the database." 
    name = gets.chomp.to_s 

    if $people[name].nil? 

     puts "What is #{name}'s age?" 
     age = gets.chomp.to_i 
     $people[name] = age.to_i 
     puts "#{name} has been succesfully added to the database." 

    else 
     puts "#{name} already exists in the database. Try again!" 

     Crud.add 
     puts $people 
    end 
end 

def self.delete 

    puts "Who would you like to delete from the database? " 

    count = 1 
    $people.each do  |name, age| 
     puts "#{count}) #{name}: #{age}" 
     count += 1 
    end 

    name = gets.chomp.to_s 

    if $people[name.to_s].nil? 
     puts "User not found. Try again!" 

    else 
     $people.delete(name) 
     puts "#{name} has been deleted from the database." 
     puts "This is the updated database: " 
     count = 1 

     $people.each do  |name, age| 
      puts "#{count}) #{name}: #{age}" 
      count += 1 
     end 
    end 
end 

def self.read 

    puts "Updated database:" 
    puts "-----------------" 
    count = 1 

    $people.each do  |name, age| 
     puts "#{count}) #{name}: #{age}" 
     count += 1 
    end 
    puts "-----------------" 
end 

def self.update 

    puts "Who would you like to update?" 
    count = 1 

    $people.each do  |name, age| 
     puts "#{count}) #{name}: #{age}" 
     count += 1 
    end 

    name = gets.chomp.to_s 

    if $people[name].nil? 
     puts "#{name} not found in the database. Try again." 
     update 

    else 
     puts "Type in a new age for #{name} " 
     age = gets.chomp.to_i 

     $people[name] = age 
     puts "#{name}'s age has been updated to #{age}" 

     puts "This is the updated database: " 
     count = 1 

     $people.each do  |name, age| 
      puts "#{count}) #{name}: #{age}" 
      count += 1 
     end 
    end 
end 

flag = true 

while flag == true 

    puts "What would you like to do?" 
    puts "1. Add, 2. Update, 3. Delete, 4. Read" 

    choice = gets.chomp 

    if choice == "1" || choice == "add" 
     Crud.add 

    elsif choice == "2" || choice == "update" 
     Crud.update 

    elsif choice == "3" || choice == "delete" 
     Crud.delete 

    elsif choice == "4" || choice == "read" 
     Crud.read 

    elsif choice == "cancel" 
     puts "Program has ended" 
     flag = false 

    else 
     puts "ERROR!! Try again" 

    end 
end

所以Ive得到這個代碼，它基本上不會創建一個CRUD（創建，讀取，更新和刪除）系統。

您只能添加與用戶對應的名稱和年齡。

我現在必須對每種方法的代碼進行自動測試。

我不完全確定如何解決問題，沒有適當的教程來做這件事。

到目前爲止，香港專業教育學院得到這個測試add方法

require "okok.rb" 
require "test/unit" 



class Test < Test::Unit::TestCase 

    def test_add() 

     add = Crud.new() 

     assert_equal... 

    end

Answer 1

嘗試分裂的兩個問題，模型和視圖：

class People 
    def initialize 
    @people = [] 
    end 

    def add(person) 
    @people << person 
    end 

    def delete(id) 
    @people.delete(find(id)) 
    end 

    def find(id) 
    @people.find { |p| p[:id] } 
    end 
end 

允許標準輸入將被注入，使你可以通過一個雙將返回在測試中的罐頭響應：

class PeopleUI 
    def initialize(dependencies = {}) 
    @stdin = dependencies.fetch(:stdin, STDIN) 
    @people = dependencies.fetch(:people, People.new) 
    end 

    def add 
    puts "What is the name?" 
    name = @stdin.gets 
    @people.add({ name: name }) 
    end 
end
