Getting Started

mkdir testdriven-app && cd testdriven-app $ mkdir services && cd services
mkdir users && cd users
mkdir project
python3.6 -m venv env
source env/bin/activate
deactivate

RUN

cd /testdriven-app/services/users/
python manage.py run

Dependencies - requirement.txt

(env)$ pip install flask==0.12.2
(env)$ pip install Werkzeug==0.16.1

Docker Config

Next, we need to create a new Docker host with Docker Machine and point the Docker client at it:

docker -v
docker-compose -v
docker-machine -v

(Optional Steps)

docker-machine create -d virtualbox testdriven-dev 
docker-machine env testdriven-dev
eval "$(docker-machine env testdriven-dev)"

Docker-compose

docker-compose -f docker-compose-dev.yml build
docker-compose -f docker-compose-dev.yml up -d

Postgres Setup :

• Add a "db" directory to "project", and add a create.sql file in that new directory:

CREATE DATABASE users_prod; 
CREATE DATABASE users_dev; 
CREATE DATABASE users_test;

• PYTHON 3 SUPPORT psycopg2==2.8.4

docker-compose -f docker-compose-dev.yml run users python manage.py recreate-db
docker exec -ti $(docker ps -aqf "name=users-db") psql -U postgres

PostresDB Commands

\c users_dev
\dt
\q

Test Setup :

• Let's get our tests up and running for this endpoint.

Add a "tests" directory to the "project" directory, and then create the following files inside the newly created directory:

1. init.py
2. base.py
3. test_config.py 4. test_users.py

RESTful Routes

• Let's set up three new routes, following RESTful best practices, with TDD:

• For each, we'll-

1. writeatest
2. runthetest,watchingitfail(red)
3. writejustenoughcodetogetthetesttopass(green)
4. refactor(ifnecessary)

POST

Add the test to the TestUserService() class in project/tests/test_users.py:
