CSC/ECE 517 Fall 2022 - E2281. Reimplement Waitlists

Topic Overview & Prior Work

Feature Overview

E2240 contains detailed information on the previous team's work with this feature.

A summary of the desired functionality is presented below:

Any instructor or TA can sign students up for a topic. Students are able to sign themselves up for a topic. If the topic is full then the team will be put on a queue or "waitlist" for the topic. If the current team holding that topic drops the topic, then the team at the top of the waitlist will be assigned the topic.

Concerns with current functionality

• What if a team is currently assigned a different topic and waitlisted for a topic that is now available?
• How many topics can a student be waitlisted for?
• If two topics become available at the same time and the same student is at the top of both waitlists, which does it choose?
• How are students notified that they were assigned a new topic?

Files Modified By Previous Team

• signed_up_team.rb
• waitlist.rb
• sign_up_sheet_controller.rb
• sign_up_sheet.rb
• sign_up_topic.rb
• suggestion_controller.rb
• invitation.rb

Problem Statement

Our goals for this project are as follows:

Code and Documentation Goals

We must explain changes made to files with diagrams and justifications.

Explanations will be provided from these perspectives:

• data flow
• functions
• code comments

Planned Work

• Add migration for "remove_column :signed_up_teams, :is_waitlisted"
• Remove all the references of is_waitlist column
• Increase the test coverage by creating new Waitlist tests (Ex. Accept Invitation, Leaving team etc.)

Testing

RSpec Unit Tests

Planned Test Cases

• Waitlist

Scenario: Student leaves a waitlisted team 
 Given: Logged in as an Student
  When: Student leaves a team
   Then: Student should be removed from all waitlisted topics associated with that team

Scenario: Instructor/TA Removes Student from Class 
 Given: Logged in as an Instructor/Admin
  When: Student is dropped from class
   Then: All topics that the student has waitlisted should be freed up

Scenario: Student accepts new team invitation 
 Given: Logged in as an Student
  When: Student accepted invitation to join team on a waitlist
   Then: Student should be added to the waitlist

Scenario: Instructor/TA Removes a topic
 Given: Logged in as an Student
  When: Instructor/TA removes a topic containing a waitlist
   Then: The waitlist should be deleted

Scenario: Student is assigned a topic and a waitlisted topic becomes available 
 Given: Logged in as an Student
  When: A topic that a student has waitlisted becomes available 
   Then: TBD

Conclusion

• Functionality: The overall functionality is good, it just requires the code be cleaned up in order to meet Ruby Stylistic Guidelines.
• Testing: Some tests will need to be created in order to test the waitlist controller, and other waitlist related functionality.
