Twyla Configuration service

This project uses Pipenv

To install for development do:

git clone https://github.com/ahussein/twyla_config_service.git
cd twyla_config_service
pipenv shell
pipenv install --dev

To run the app, you need a DB instance running and you can use an environment variable to point to your running DB instance like the following:

export DB_URI='mongodb://localhost:27017/testdb'

If the environment is not set, then the app will try to connect to the following URI:

mongodb://localhost:27017/twyla_configs

After making sure the DB instance is up and running you can start the app service using the following command:

python3 app/app.py

To run the tests with coverage report, do:

pytest -v --cov=./app test

The above tests requires a DB instance to be running since it includes integration tests. To run only unittests do:

pytest -v test/unittests

-----------------Load Testing The Service -----------------For load testing, I have picked up Locust: https://locust.io/ It is python based, so tests are written in python and it has a nice UI as well. Make sure to have your virtualenv is activated and then:

pipenv install locustio
locust -f load_test.py --no-web -c 1000 -r 10 --host=http://localhost:8000 --csv=load_test_result.csv

This will start the load tester with a 1000 user each of them is trying to execute a mixure of the the exposed endpoints. The above command will run the load tests in no-ui mode and you can choose to run with the UI mode. Please check the docs for more details here: https://docs.locust.io/en/latest/what-is-locust.html
