Example project for pytest tutorial

This example project implements a small app named "networker" that can draw force layouts for a directory of JSON graphs.

Installation

Requirements

Software:

• Python >=2.7.11 or >3.3
• pip >= 8.1
• a recent web browser
• Optional: git, virtualenv

Abilities that will help you:

• know how to use your Terminal (changing directories, executing scripts)
• basic Python (functions, imports, decorators)

Optional: set up a virtual environment

For Python 2:

pip install virtualenv
cd <tutorial folder>
pyvenv env
source env/bin/activate

For Python 3:

cd <tutorial folder>
python3 -m venv env
source env/bin/activate

Install pytest and the package in developer mode

Run the following in the tutorial folder.

# May be pip3 on your system
pip install --user pytest pytest-cov
pip install --user -e .

Try the app

Run the app in the tutorial folder with

# may be python3 on your system
python -m networker

Open your browser at https://localhost:5000/miserables and check whether you see the graph.

In total the app has the following routes:

• /<filename> - create the graph for the file <filename> (you can omit the extension)
• /json/<filename> - get the JSON from a file <filename>
• /validate/<filename> - check whether <filename> contains a valid JSON graph
