Testing for computational notebooks

An extension for Jupyter Notebooks that supports a novel testing interaction in computational notebooks.

This system was created using the Cursor IDE, which has an embedded AI-backed programming tool that I used. To get familiar with creating a custom Jupyter Notebook extension, I referenced this resource by Aneesha Bakharia.

Running a Custom Jupyter Notebook Extension

Apologies to the unlucky grader in advance, but running a custom extension will require some set-up. Feel free to email me at xrl@seas.upenn.edu so I can show the extension on my system if you run into any issues. This installation guide is based on the resource linked above.

1) Create a new conda virtual environment

$ conda create --name jupyterexperiments python=3.11 
$ conda activate jupyterexperiments
$ conda install -c conda-forge jupyter_contrib_nbextensions

2) Find the extensions directory

$ pip show jupyter_contrib_nbextensions

This shows you where the package is installed. Look for the Location: line in the output.
Navigate to the nbextensions folder and clone this repository. Your final file structure should resemble the following.

# Your File Structure Should Look Like This:
/Users/username/anaconda3/envs/jupyterexperiments/lib/python3.11/site-packages/
└── jupyter_contrib_nbextensions/
    └── nbextensions/                                         ← CLONE THIS REPOSITORY HERE
        └── testing_for_computational_notebooks/             
            └── main.js
            └── ...                   

3) Install and enable the extension

Stay in the nbextensions folder. Then, run the following:

$ jupyter nbextension install testing_for_computational_notebooks --user
$ jupyter nbextension enable testing_for_computational_notebooks/main

4) Open a notebook

Finally, open a notebook. This can be done through a locally hosted notebook by clicking the "New --> Python 3 (ipykernel)" widget after running the command below.

$ jupyter notebook

You should see the widgets that enable the modifications present in the submitted video. The functionalities are in accordance with the Technical Requirements list here.
