Congratulations! You're submitting your assignment!

You and your partner should collaborate on the answers to these questions.

Comprehension Questions

Question	Answer
How did you go about exploring the Slack API? Did you learn anything that would be useful for your next project involving an API?	I learned that there are get and post requests and each one can have different parameters. Each API has its own naming, so they will change depending the API.
Give a short summary of the request/response cycle. Where does your program fit into that scheme?	User selects an option, then program runs and sends a get or post request to the server depending user input, server checks the request and sends back a response.
How does your program check for and handle errors when using the Slack API?	the program checks that the query is valid and sends code different than 200 and ok if it is invalid.
Did you need to make any changes to the design work we did in class? If so, what were they?	I did few changes. I didn't implement the abstract method in recipient.
Did you use any of the inheritance idioms we've talked about in class? How?	Yes, I created a parent class called recipient, so user class and channel class inherit name and id from it.
How does VCR aid in testing a program that uses an API?	It records the first time the program sends a request to the server in testing and then everytime, you run same test, it runs same recorded response preventing a new call to the server.

…lso, set up test helper with all require_realtives.

What We're Looking For

Feature	Feedback
Core Requirements
Git hygiene (no slack tokens)	Great!
Comprehension questions	good
Functionality
List users/channels	yes
Select user/channel	yes
Show details	yes
Send message	yes
Program runs without crashing	yes
Implementation
API errors are handled appropriately	yes
Inheritance model matches in-class activity	no
Inheritance idioms (abstract class, template methods, polymorphism) used appropriately	no, you've diverged pretty heavily in this case. You've completely removed template methods, meaning that your work for something like `list_channels` is duplicated.
Methods are used to break work down into simpler tasks	mostly, see comment.
Class and instance methods are used appropriately	yes
Tests written for User functionality	yes
Tests written for Channel Functionality	yes
Tests written for sending a message	yes
Overall	Good work overall! You've got a few bumps in terms of how you chose to deviate from the design we gave you, and I hope my comments help you understand why we laid the project out the way we did! Keep up the hard work.

Which are messy and make it hard to debug, but also often hint at bigger problems with code.

You've included this here...

These two lines print every time you come back to the top of the loop, but it would make more sense for them to only print when the CLI starts.

+      puts "Please enter username or Slack ID"

I'd love to see some sort of confirmation message if things went right here.

+      elsif recipient.class == Slack::User
+        print "Please enter the message: "
+        message = gets.chomp

consider breaking these larger blocks out into helper methods so that this logic is easier to read!

lib/message.rb

+class SlackApiError < StandardError ; end
+
+module Slack  
+  def self.send_msg(message, channel)


If you're going to go the route of making an API wrapper, move all of the messages into the wrapper!

lib/channel.rb

+
+    def self.channels_list
+      channels = []
+      response = HTTParty.get("#{CHANNEL_URI}/channels.list", query: {token: CHANNEL_KEY}) 


The route I'd rather see you go here is to have a generic list method for both channels and users that you implement in recipient, which could call a method that actually parses the response appropriately, similar to what csv_record did in OO ride share

lib/recipient.rb

+    attr_reader :name, :id

If you're writing a class this short, ask yourself 2 questions:

If it's this short, do I need it?

If it's needed, is someone else doing its job?
