A utility repository for beginning development with A+ and related services

Getting started

1. Install required software

   # Aalto Linux
   pkcon install gettext python3-venv
   
   # Debian-based Linux with administrator permissions
   sudo apt update
   sudo apt install gettext python3-venv
   
   # Apple macOS
   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
   brew install gettext
   

2. Clone the repository

   git clone git@github.com:apluslms/develop-aplus.git
   

3. Move to the directory

   cd develop-aplus
   

4. Initialize the development environment and activate the Python virtual environment

   source ./init-env.sh
   

5. Run the Docker containers

   ./docker-up.sh
   

Done!

The A+ development code in the a-plus submodule has been mounted and your code changes in the a-plus directory are now visible at http://localhost:8000/. To mount development code for the other services, edit the docker-compose.yml by uncommenting the relevant lines under the volumes section.

After the development environment has been initialized once by running ./init-env.sh, the next time you only need to activate the virtual environment before running the Docker containers:

source .venv/bin/activate
./docker-up.sh

Pushing code changes to your forked repository

The upstream/origin for the submodules a-plus, mooc-grader, gitmanager, mooc-jutut, and aplus-manual is the apluslms organization. You should fork the GitHub repositories that you are working on and push code changes to your own repository first and then create a pull request.

Example:

How to add your forked a-plus repository to the submodule as a remote and push changes to it:

1. Move to the a-plus submodule directory under develop-aplus

   cd a-plus
   

2. Add your fork as a remote and give it a name, such as your GitHub username

   git remote add <myusername> git@github.com:<myusername>/a-plus.git
   git fetch <myusername>
   

3. Create a new branch for the new code changes

   git switch -c <mybranch>
   

4. Make your changes
5. Push the changes to your forked repository

   git add somefile.py
   git commit
   git push <myusername>
   

6. Create a GitHub pull request

Debugging with VSCode

How to debug

1. Open the develop-aplus directory in VSCode as a VSCode Workspace
2. Run the containers with ./docker-up.sh
3. Open the VSCode Run and Debug tab
4. Attach to, for example, the A+ container with the Remote Attach to A+ debug configuration
5. Set your breakpoints in the code

SystemExit exception

Django automatic reloads cause VSCode to stop on the SystemExit exception. This behaviour can be stopped by unchecking the Uncaught Exceptions option in the breakpoints panel of the Run and Debug tab.

Running tests

In the develop-aplus root directory, first activate the virtual environment:

source .venv/bin/activate

A+ tests

Running A+ tests in VSCode

The A+ tests can be run conveniently in VSCode's Testing tab.

If the Testing tab is missing or does not immediately show any tests, make sure to first open the develop-aplus directory in VSCode as a VSCode Workspace. Next, install the VSCode Python extension by microsoft and then activate the correct Python interpreter in VSCode. Selecting the interpreter is done by pressing Ctrl + Shift + P (or Cmd + Shift + P on macOS) and searching for Python: Select Interpreter. Select the Python virtual environment interpreter located at .venv/bin/python.

Running A+ tests in terminal

In order to run tests in the terminal, first move to the a-plus directory:

cd a-plus

Run all tests:

pytest

Run Playwright end-to-end tests only:

pytest e2e_tests

Run and debug a specific Playwright end-to-end test:

PWDEBUG=1 pytest -s -k <test_method_name>

Run unit tests only:

pytest --ignore=e2e_tests

Run and debug a specific unit test:

pytest -s -k <test_method_name>

An alternative way to run A+ unit tests only:

python3 manage.py test

MOOC-Grader tests

Move to the mooc-grader directory:

cd mooc-grader

Run all tests inside a Docker container:

docker-compose -f docker-compose.test.yml up grader_unit

Git manager tests

Move to the gitmanager directory:

cd gitmanager

Run all tests inside a Docker container:

docker-compose -f docker-compose.test.yml up gitmanager_unit

How to generate/post submissions to A+ automatically

Run ./generate-submissions.sh in the root of this repository.

Check the README.md in the utils/submission-generator directory.
