Prerequisites

In order for this project's dependencies to install, you'll need PostgreSQL running on your computer.

Install it by opening your terminal, and pasting the following command:

brew install postgresql

Setup

Clone this repository to your computer.

Take a look at the test code in books_app/main/tests.py. There are several existing tests that you can use as examples.

To run the code, navigate to the project folder and run the following to install the required packages:

pip3 install -r requirements.txt

Then, copy the .env.example file to .env:

cp .env.example .env

Then you can run the following to run the Flask server:

python3 app.py

Running the Tests

To run all of the tests, you can run the following from the root project directory:

python3 -m unittest discover

(Make sure you have unittest installed.)

To run all tests from a single file, run the following:

python3 -m unittest books_app.main.tests

To run one specific test, you can run the following:

python3 -m unittest books_app.main.tests.MainTests.test_homepage_logged_in

Instructions

Navigate to books_app/main/tests.py and books_app/auth/tests.py, and complete the TODOs to finish all tests. Make sure you run the tests as you go along to ensure that they still pass!
