Background
To manage the transition from trimesters to hexamesters in 2020, UNSW
has established a new focus on building an in-house digital collaboration
and communication tool for groups and teams.
Rather than re-invent the wheel, UNSW has decided that it finds the
functionality of Slack to be nearly exactly what it needs. For this reason,
UNSW has contracted out Rayden Pty Ltd (a small software business run
by Rob and Hayden) to build the new product. In UNSW’s attempt to
connect with the younger and more “hip” generation that fell in love with
flickr, Tumblr, etc, they would like to call the new UNSW-based product
slackr.
Rayden Pty Ltd has sub-contracted two software firms:
• BananaPie Pty Ltd (two software developers, Sally and Bob, who will build
the initial web-based GUI)
• YourTeam Pty Ltd (a team of talented misfits completing COMP1531 in
19T3), who will build the backend python server and possibly assist in the
GUI later in the project
In summary, UNSW contracts Rayden Pty Ltd, who sub contracts:
• BananaPie (Sally and Bob) for front end work
• YourTeam (you and others) for backend work
Rayden Pty Ltd met with Sally and Bob (the front end development team)
2 weeks ago to brief them on this project. While you are still trying to get
up to speed on the requirements of this project, Sally and Bob understand
the requirements of the project very well.
Because of this they have already specified a common interface for the
front end and backend to operate on. This allows both parties to go off
and do their own development and testing under the assumption that
both parties comply will comply with the common interface. This is the
interface you are required to use
Beside the information available in the interface that Sally and Bob
provided, you have been told (so far) that the features of slackr that
UNSW would like to see implemented include:
- Ability to login, register if not logged in, and log out
- Ability to reset password if forgotten it
- Ability to see a list of channels
- Ability to create a channel, join a channel, invite someone else to a
channel, and leave a channel - Within a channel, ability to view all messages, view the members of the
channel, and the details of the channel - Within a channel, ability to send a message now, or to send a message at
a specified time in the future - Within a channel, ability to edit, remove, pin, unpin, react, or unreact to a
message - Ability to view user anyone’s user profile, and modify a user’s own profile
(name, email, handle, and profile photo) - Ability to search for messages based on a search string
10.Ability to modify a user’s admin privileges: (MEMBER, ADMIN, OWNER)
11.Ability to begin a “standup”, which is a 15 minute period where users can
send messages that at the end of the period will automatically be collated
and summarised to all users
To get further information about the requirements, Rayden Pty Ltd will
provide a pre-recorded video briefing (with verbal and visual descriptions)
of what they’d like to see in the Slackr product. This will be released on
September 23rd.
Setup
After your week 2 tutorial, you should know who your team members are.
Follow the instructions on the tutorial sheet to ensure your team is
registered. You need to do this by Thursday 9PM in week 2.
If you registered your team on time, then on Sunday of week 2, you
should have access to an individual repository at this URL:
https://gitlab.cse.unsw.edu.au/COMP1531/19T3/team_name
where team-name is the name of your group as registered on the course
website.
Progress check-in
During your lab class, in weeks without demonstrations (see below), you
and your team will conduct a short stand-up in the presence of your tutor.
Each member of the team will briefly state what they have done in the
past week, what they intend to do over the next week, and what issues
they faced or are currently facing. This is so your tutor, who is acting as a
representative of the client, is kept informed of your progress. They will
make note of your presence and may ask you to elaborate on the work
you’ve done.
Iteration 1: Tests and Stories
Task
In this iteration, you are expected to: - Create extensive tests (using pytest) for all of the functions in the agreed
upon interface.
These should all be in files of the formn *_test.py. See below for more
information. - Create user stories for your current understanding of the product based
on your previous understanding of a slack-like app.
Each individual story should form its own card on the project task board. - Write assumptions that you feel you are making in your interpretation of
the specification and of the functions provided.
Write these in markdown in assumptions.md. - Write a brief 1-page plan highlighting how you will approach the following
iteration (the development stage).
Write these in markdown in plan.md. You may include diagrams, tables or
whatever other information you believe conveys your plan. - Write a brief 1-page reflection on how this iteration has gone and how you
successfully operated as a well-functioning team.
Write these in markdown in reflection.md.
You are not expected to begin developing or completing the actual
functions themselves.
The files described above should all be in the root of your repository. If
you’ve not written markdown before (which we assume most of you
haven’t), it’s not necessary to research the format. Markdown is
essentially plain text with a few extra features for basic formatting. You
can just stick with plain text if you find that easier.
Tests
It is up to you how you structure your tests, but we do require that you
write all of your stubs and tests in the /server/ folder.
Our recommendation is to break all of the functions to test up into 1 or
many files (this is a decision for you and your team), and then create test
files in the same directory as the files the tests are testing. An example of
this has been done with:
•
/server/echo.py
/server/echo_test.py
• Remember that we encourage you to write stub functions for all of the
functions we provide. Stub functions are dummy implementations of
functions that allow them to be trivially tested. E.G. A stub function for a
user to login may always return a dummy auth token “123456”. This will
allow your tests to successfully compile. It is expected that some errors
may appear in your tests as you write them that you won’t discover until
you develop the backend in iteration 2.
You may also wish to create some helper files with extra helper functions
if that would assist you writing your tests.
(More info) User Stories
The scaffold for user stories will be provided in the lecture on Monday
23rd September. Please refer to that lecture for information about the
structure of the user stories.
Submission
This iteration is due to be submitted at 5pm Sunday 6th October (week 3).
You will then be demonstrating this in your week 4 lab. All team members
must attend this lab session.
To submit, run this command in the CSE environment:
1531 submit iteration1
This will submit the contents of your repo on GitLab and perform a check
to make sure that the files above are present. Make sure that everything
you intend to submit is included in your repo. User stories should be
entered into GitLab on the task board for your project.

Advice
• Do NOT attempt to try and write or start a web server. Don’t overthink
how these functions are meant to connect to a frontend yet. This is for the
next iteration. In this iteration you are just focusing on the high level
functions that will eventually be used for a web server.
• While we don’t encourage you to implement the functions (because the
specification may change, and there are no marks for implementation),
we do encourage you to sufficiently “stub” out the functions to ensure
they’re testable and that your python tests can actually compile and
run
Demonstration
When you demonstrate this iteration in your week 4 lab, the breakdown
will go approximately like this:
• 5 minutes of demonstration of the code you produced
• 5 minutes of demonstration of your stories, assumptions, and plan
• 10 minutes of Q&A from the tutor(s)
Iteration 2: Servers and Products

Expectations
While it is up to you as a team to decide how work is distributed between
you, for the purpose of assessment there are certain key criteria all
members must.
• Code contribution
• Documentation contribution
• Usage of git/GitLab
• Attendance
• Peer assessment
• Academic conduct
The details of each of these is below.
While, in general, all team members will receive the same mark (a sum of
the marks for each iteration), if you as an individual fail to meet these
criteria your final project mark may be scaled down, most likely quite
significantly.
Code contribution
All team members must contribute code to the project. Tutors will assess
the degree to which you have contributed by looking at your git history
and analysing lines of code, number of commits, timing of commits, etc. If
you contribute significantly less code than your team members, your work
will be closely examined to determine what scaling needs to be applied.
Documentation contribution
All team members must contribute documentation to the project. Tutors
will assess the degree to which you have contributed by looking at your git
history but also asking questions (essentially interviewing you) during
your demonstration.
Note that, contributing more documentation is not a substitute for not
contributing code.
Peer Assessment
You will be required to complete a form in week 10 where you rate each
team member’s contribution to the project and leave any comments you
have about them. Information on how you can access this form will be
released closer to Week 10. Your other team members will not be able to
see how you rated them or what comments you left.
If your team members give you a less than satisfactory rating, your
contribution will be scrutinised and you may find your final mark scaled
down.
Attendance
It is generally assumed that all team members will be present at the
demonstrations and at weekly check-ins. If you’re absent for more than
80% of the weekly check-ins or any of the demonstrations, your mark may
be scaled down.
If, due to exceptional circumstances, you are unable to attend your lab for
a demonstration, inform your tutor as soon as you can so they can record
your absence as planned.
Plagiarism
The work you and your group submit must be your own work. Submission
of work partially or completely derived from any other person or jointly
written with any other person is not permitted. The penalties for such an
offence may include negative marks, automatic failure of the course and
possibly other academic discipline. Assignment submissions will be
examined both automatically and manually for such submissions.
Relevant scholarship authorities will be informed if students holding
scholarships are involved in an incident of plagiarism or other
misconduct.
Do not provide or show your project work to any other person, except for
your group and the teaching staff of COMP1531. If you knowingly provide
or show your assignment work to another person for any reason, and
work derived from it is submitted you may be penalized, even if the work
was submitted without your knowledge or consent. This may apply even if
your work is submitted by a third party unknown to you.
Note, you will not be penalized if your work has the potential to be taken
without your consent or knowledge.
