E1414: Testing classes related to teams

Please be advised that we do not have deployment link, since our work are all back-end tests

Introduction

This project will be an extension of our previous E1406 project. For the previous project, we did some refactoring and testing for the controllers related to teams. This time, we are going to reuse most of our test environment, but extend the tests to other team-related classes. We also expect to examine and report the code that may require refactoring.

Test Environment

Framework

Rails default test framework

Sample data

Fixtures (under /test/fixtures)

Background

teams_users.rb & teams_users_controller.rb

• Teams_users.rb and teams_users_controller.rb are used for Instructor/TA to manage the members of teams.
• There is no functional test for teams_users_controller.rb and unit test for teams_users.rb in the current version of expertiza codes.

teams_participant.rb & teams_participant_controller.rb

• teams_participant.rb and teams_participant_controller.rb are used to manage the participants of teams.
• There is no functional test for teams_participant_controller.rb and unit test for teams_participant.rb in the current version of expertiza codes.

advertise_for_partner.rb

• This controller takes over the advertisement function from the student_team_controller, and make the class more RESTful.
• It seems like there has been a functional test, but the class name and set up looks like the other class. It may be necessary to re-run, and even re-write the test

team.rb

• This model defines the relationship between team object and other objects. It also has other methods to handle related functions about team operation
• There exists a unit test for team model, but there are only two test cases. Also, some of the methods under team.rb are duplicated, or either marked as not working. Further research may be required before starting to do the test.

Classes

app/models/teams_users.rb

The teams_users.rb is a model belonging to both users and teams. It is used when a user is added to a team.

app/controllers/teams_users_controller.rb

The teams_users_controller support team member management for instructor/TA accounts Instruction/TA can:

• get a user name by inputting part of the name
• list team members of a team
• add a user to a team
• remove a team member from a team
• remove all members belonging to an item

app/controllers/advertise_for_partners_controller.rb

The advertise_for_partners_controller work with the student_team_controllers, allowing student manage advertisement for their teams.

A student can:

• create a new advertisement for the team
• edit the advertisement content
• remove advertisement record from the table for the specific team

app/models/teams_participant.rb

The teams_participant.rb is a model belonging to both users and teams. It is used when a team participant is created, listed or deleted.

app/controllers/teams_participant_controller.rb

The teams_participant_controller support team participants management so the team participant:

• get a participant name by inputting part of the name
• list team participants of a team
• add a participant to a team
• remove a selected team participant from a team
• remove all team participants belonging to an item

app/models/team.rb

The “team” object represents a team that consists students who are either participants of course or assignment. a team will response to the request on:

get_participants

get participant in the team

delete

delete a team member in the team

get_node_type

will return “TeamNode”

get_author_name

will return team’s name

generate_team_name()

serialize the automatically generated team name (e.g. team 1, team 2, etc.)

get_possible_team_members(name)

find a team member by name

has_user(user

find a team member by user object

add_member(user, assignment_id)

add a user to an assignment team

copy_members(new_team)

copy current member in the team to the new team

create_node_object(name, parent_id)

‘’there is a TODO on this method indicated that this is not working’’

check_for_exisiting(parent, name, team_type)

check if the team name under the same assignment or course is in use.

Delete_all_by_parent(parent)

delete all teams under the same course/assignment

Randomize_all_by_parent(parent, team_type, team_size)

randomly assign team members

generate_team_name(teamnameprefix)

generate team name with prefix (e.g. prefix_Team1)

import_team_members(starting_index, row)

import user from specific index of users and length

Setup

To set up our testing for the models and controllers, we need some fixtures to support. Fixtures needed for corresponding classes are listed below

fixtures use in common

• teams.yml
• users.yml
• teams_users.yml
• courses.yml
• assignments.yml

teams_participant.rb & teams_participant_controller.rb

Besides the above fixtures, we also need the following fixrure

• teams_participant.yml

teams.rb

• teams_participant.yml
• join_team_requests.yml
• participants.yml
• nodes.yml

Testing Scenarios

teams_users.rb & teams_users_controller.rb

Based on the user story of the teams_users_controller.rb, there are also several sub-scenarios for each method in the user story.

• Auto_complete_for_user_name:
  • Test auto_complete_for_user_name with valid user name
  • Test auto_complete_for_user_name with invalid user name

• List
  • Test List with valid team id
  • Test List with invalid team id

• New
  • Test New with valid team id
  • Test New with invalid team id

• Create
  • Test Create with valid team id
    • Test Create with valid user id and maximum member number is not reached
    • Test Create with invalid user id and maximum member number is not reached
    • Test Create with valid user id and maximum member number is reached
    • Test Create with invalid user id and maximum member number is reached
  • Test Create with invalid team id
    • Test Create with valid user id and maximum member number is not reached
    • Test Create with invalid user id and maximum member number is not reached
    • Test Create with valid user id and maximum member number is reached
    • Test Create with invalid user id and maximum member number is reached

• Delete
  • Test Delete with valid user id
  • Test Delete with invalid user id

• Delete_select
  • Test Delete_select with valid item id
  • Test Delete_select with invalid item id

For the methods in teams_user.rb, the scenarios would be like the following:

• Delete
  • Test Delete to check if it could delete the team node and the team user

• Remove_team
  • Test Remove_team with valid user_id and valid team_id
  • Test Remove_team with valid user_id and invalid team_id
  • Test Remove_team with invalid user_id and valid team_id
  • Test Remove_team with invalid user_id and invalid team_id

• Is_team_empty
  • Test Is_team_empty with empty team
  • Test Is_team_empty with non-empty team

• Add_member_to_invited_team
  • Test Add_member_to_invited_team with valid user_id and valid team_id
  • Test Add_member_to_invited_team with valid user_id and invalid team_id
  • Test Add_member_to_invited_team with invalid user_id and valid team_id

• remove
  • test remove with valid user id
  • test remove with invalid user id

• import_team_members(starting_index, row)
  • test import team members with valid index and row
  • test import team members with invalid index and row

Possible Refacotring

advertise_for_team_controller.rb

• update should be edit (this is mentioned in the comments of code)
• edit should be reexamined since it is only retrieving the team object
• new is empty, so it should be removed

team.rb

• There are two def get_participants, the second one overwritten the first one, so the first one should be deleted.

Running Tests

Please note that all of our work will be under the /test folder, which means they will not show any change on the view. To see the result of tests, run

rake test TEST=test/unit/<filename> # for models

and

rake test TEST=test/functional/<filename> # for controllers

running the whole test suite with rake test is not recommended, as the schema change overtime has broke some of the previous tests.

Sample Test Code

We show two pieces of test code for two controllers from our previous work to explain how our test works

   test "create_student team with name in use" do
       sessionVars = session_for(users(:student8))
       post(:create, {'team' => { 'name' => 'IntelligentTeam2'}, 'id' => participants(:par21).id, "commit" => "Create Team"}, sessionVars, nil)
       assert_equal 'Team name is already in use.', flash[:notice]
       assert_redirected_to :controller => 'student_team', :action => 'view', :id => participants(:par21).id
   end

   test "create_should_increase_number_of_teams_course" do
       sessionVars = session_for(users(:instructor1))
       sessionVars[:team_type] = "Course"
       assert_difference 'Team.count' do
         get :create, {'id' => @testCourse,'team' => {'name' => "Random"}},sessionVars
       end
   end

The first piece of code is from student_team_controller.rb. It tests if there is already a same team name when student8 want to create a team. The second piece of code is from teams_controller_test.rb. It tests if the team number decreases when instructor1 creates a new team for a course.

As we can see from the code, when we want to use post or get, several parameters are needed. Usually we use four parameters: First, the method we are requesting. Second, an hash of request parameters for the method. Third, an optional hash of session variables. Forth, an optional hash of flash values. If we do not want to pass in the optional hash, we can set it to nil as the first piece of code shows, or we can just leave it blank as the second piece of code shows.

When we run the command rake test TEST=test/functional/your_test_file.rb, you will see if the test is passed or not.
