A django app to conduct online programming tests.

Project description


Build Status Documentation Status

To get an overview of the Yaksh interface please refer to the user documentation at Yaksh Docs

This is a Quickstart guide to help users setup a trial instance. If you wish to deploy Yaksh in a production environment here is a Production Deployment Guide


This project provides an “exam” app that lets users take an online programming quiz.


  • Define fairly complicated programming problems and have users solve the problem.

  • Immediate verification of code solution.

  • Supports pretty much arbitrary coding questions in Python, C, C++ and simple Bash and uses “test cases” to test the implementations of the students.

  • Supports simple multiple choice questions and File uploads.

  • Since it runs on your Python, you could technically test any Python based library.

  • Scales to over 500+ simultaneous users.

  • Distributed under the BSD license.

Quick Start


  1. Ensure you have Python available.

  2. Ensure pip is installed.


  1. Install yaksh

    • Clone the repository

      $ git clone
    • Go to the online_test directory

      $ cd ./online_test
    • Install the dependencies

      • For Python 2 use:

        $ pip install -r ./requirements/requirements-py2.txt
      • For Python 3 (recommended) use:

        $ pip install -r ./requirements/requirements-py3.txt

Short instructions

  1. Start up the code server that executes the user code safely:

    • To run the code server in a sandboxed docker environment, run the command:

      $ invoke start
    • Make sure that you have Docker installed on your system beforehand. Docker Installation

    • To run the code server without docker, locally use:

      $ invoke start --unsafe
    • Note this command will run the yaksh code server locally on your machine and is susceptible to malicious code. You will have to install the code server requirements in sudo mode.

  2. On another terminal, run the application using the following command:

    $ invoke serve
    • Note: The serve command will run the django application server on the 8000 port and hence this port will be unavailable to other processes.

  3. Open your browser and open the URL http://localhost:8000/exam

  4. Login as a teacher to edit the quiz or as a student to take the quiz Credentials:

    • Student - Username: student | Password: student

    • Teacher - Username: teacher | Password: teacher

  5. User can also login to the Default Django admin using;

    • Admin - Username: admin | Password: admin


At FOSSEE, Nishanth had implemented a nice django based app to test for multiple-choice questions. Prabhu Ramachandran was inspired by a programming contest that he saw at PyCon APAC 2011. Chris Boesch, who administered the contest, used a nice web application Singpath that he had built on top of GAE that basically checked your Python code, live. This made it fun and interesting.

Prabhu wanted an implementation that was not tied to GAE and hence wrote the initial cut of what is now ‘Yaksh’. The idea being that anyone can use this to test students programming skills and not have to worry about grading their answers manually and instead do so on their machines.

The application has since been refactored and maintained by FOSSEE Developers.
