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?	We used the documentation and Postman to test out the Slack API. We learned that it's useful to look through the documentation thoroughly -- we found additional endpoints to use that weren't in the project instructions.
Give a short summary of the request/response cycle. Where does your program fit into that scheme?	The user sends a request to the API with a key and relevant parameters, then the API sends back a response containing the requested information or an error message. Our program constructs the request and then it interprets the response from the API. It then formats the response for the user to understand.
How does your program check for and handle errors when using the Slack API?	It checks for and handles errors in the same methods that call the API. It interprets the JSON file when there is an error and sends back a message to the user. We also stop the user from entering information that might cause an error in sending a request to the API.
Did you need to make any changes to the design work we did in class? If so, what were they?	Our initial design included a message class, which we removed because the message was not significant enough in this program.
Did you use any of the inheritance idioms we've talked about in class? How?	We used polymorphism in the child classes of Recipient in self.get. The code was defined in Recipient and the only different between the implementations in User and Channel was that they passed in different URLs. Details was a template method defined in the abstract class, Recipient, but in User and Channel the code was different because they dealt with different pieces of information.
How does VCR aid in testing a program that uses an API?	It aids in that it allows the tests to be run several times without actually calling the API, which could take time, money, and could have a rate limit.

… a test

…ponse, added test with cassette created with bad token

…onality to workspace and tests.

…workspace_test to use VCR for show_details test.

lib/channel.rb

+      key = ENV["API_TOKEN"]
+      response = HTTParty.get("https://slack.com/api/channels.info", query: {token: key , channel: @slack_id})
+      if response.keys.include? "error"  || response["ok"] == false
+        raise SlackCLI::SlackApiError


It would be nice if you'd included what the error was in the message here.

Suggested change

raise SlackCLI::SlackApiError

raise SlackCLI::SlackApiError.new(response["error"])

lib/recipient.rb

+      if response.keys.include? "error"  || response["ok"] == false
+        raise SlackCLI::SlackApiError.new("Message not sent due to error: #{response["error"]}")
+      else
+        return true


I appreciate what you're doing here but since this method raises the only thing it can ever return is true so I probably wouldn't bother with returning something.

lib/recipient.rb

+    end
+
+    def self.list
+      raise NotImplementedError.new("Self.list should be implemented in child class")


Abstract methods! 🎉

lib/slack.rb

+      puts "Select Channel"
+      print "Please enter a Channel Name or Slack ID: "
+      query = gets.chomp.downcase
+      query_result = workspace.select_channel(query)


I'd have liked to have seen the error here handled with an exception and then rescued down below. That way the message could be constructed inside of select_channel and you wouldn't need the extra check below.

Plus, it could give you to opportunity to DRY up your code by putting all of your error handling in a single begin/rescue within your until wrapping your case.

lib/recipient.rb

+          }
+        )
+
+      if response.keys.include? "error"  || response["ok"] == false


You should be checking response.code here.

lib/user.rb

+
+    def details
+      key = ENV["API_TOKEN"]
+      response = HTTParty.get("https://slack.com/api/users.info", query: {token: key , user: @slack_id})


If you made self.get accept parameters then you could have avoided duplicating error handling.
