Assignment: Quiz Script

This repository is compatible with Replit.

Materials within this repo

There are few major files here.

• main.py is the main code base file. It will be used to complete the assignment by students.
• tests directory is the home of all tests provided for the assignment.
• .lesson directory is the documentation source
  • .lesson/instructions.md is the assignment instructions file visible for all.
  • .lesson/lessonplan.md is the private file, available only for the assignment owners and/or admins. Do not add solution to this file. Use it for notes for the assignment.
  • .lesson/assets is the home for all static files required by the docs.

Other documents may be included into .lesson directory. Only instructions.md will be visible for the students.

This repository stores its own assets within .lesson directory as well.

Set up assignment repository

Creating a new repository from template

Press the Use this template green button at the top.

This will lead you to the repository creation page. Provide a valid meaningful repo name and add its description.

There is no need to clone branches except master. Default branch is always at the most stable version.

Protect master branch

It's important not to work within the default branch. So, ensure noone can commit directly into master. In Settings navigate to Branches under the Code and automation section. Press Add branch protection rule button.

Provide branch name pattern and check following options:

• Require a pull request before merging
• Require status checks to pass before merging
  • Require branches to be up date before merging
• Do not allow bypassing the above settings

This will protect the default branch from committing directly into it. You may apply other protection rules, in case of need.

Create a branch protection rule.

Getting started

1. Clone your assignment repo to your local machine.
2. Create a new topic branch (e.g. feature/assignment).
3. Complete the assignment instructions. Provide a clear objective and usage examples.
4. Prepare the code boilerplate file (main.py).
5. Add test cases (use unittest framework only).

Make your boilerplate file invisible for Git

When a boilerplate code is ready, you may want to implement the actual logic for the assignment. It's useful for running tests especially. However, you do not want to put the implementation to the assignment repository.

To make changes inside a file invisible for Git use:

git update-index --assume-unchanged <file>

To switch it back:

git update-index --no-assume-unchanged <file>

Always do this while working with non-boilerplate code inside main.py.

Testing

Assignment follows TDD approach. This means all the tests should fail. Decorate your test cases with unittest.expectedFailure. Otherwise, it will be impossible to merge topic branch into master.

Add the assignment to Replit

There is no way to import GitHub repo as lesson project to Replit. So, it's a little bit tricky to connect the Replit project with a GitHub repository.

Navigate to EDU organization's team and press Create project button.

Provide all the information about the assignment.

There is an assignments library of current course available on Replit. For the assignments within this team, there is no need to set a due date. Assignments will be copied to other working teams from here.

In the repl, first press Add lesson contents button. Replit does not remove it, until it hasn't been clicked. And this may be annoying to see it each time. After that open Git tab, by pressing the corresponding button inside Tools section.

On Git tab uncheck "Create initial commit with all changes" option. The GitHub repo is the only source of any changes for the assignment. After that press Initialize Git Repository.

On Git tab press Reset All button. Approve discard changes actions.

In the Tools section press Shell button to access the shell. Add remote repository as common. Note, it may be tricky to use SSH access. Any way, HTTP will be quite enough until you aren't going to use Replit for the assignment preparation works. After that fetch all the changes and switch to master branch.

git remote add origin <remote_repo_url>
git fetch
git switch master

The repl set up is complete at this point.

Add Replit project tests

In Tools section press Tests button and choose a testing method, Unit tests will be suitable in most cases.

First you need to set up unit tests. In a setup window add required imports. Also, you can provide setUp and tearDown methods within advanced setup section.

After the unittest framework is set up, it a copy-paste time. Add tests by pressing Add test button. Provide a test name (omit "test" at the beginning), error message and the test's code itself. Press Create test button when ready.

Providing a solution for students

On the repls overview page, press "three-dots" button on a repl and select Create solution option.

This will create a new repl, there you may provide the solution. Once you're done - press Create/Update solution button in the top-right corner. Set up when the solution is available for the students.

Publish the assignment

When the assignment is ready, simply check Published. Alternatively, you may press Publish project button in the top-right corner of the Repl page.

Published flag is used to track assignment that are ready.
