QA: Quality Assurance of web applicationsHow do you set up a environment for QA ?

(involves a human going through test cases)

How to set up QA environment

• ngrok

• expose local environment through proxy

• docker machine

• deploy conteiners to public environment

• docker + hipache proxy etc..

Run multiple QA environments simultaneously

Perform QA each feature branches

feature-A

feature-B

feature-C

Solution: run containers each feature branches

Access a container with using a URL contains branch name

Running a container on demand

http://feature-A.app.dev

http://feature-B.app.dev

http://feature-C.app.dev




DEMO NOTE: prevs.io is still under WIP :-)

prevs.io provides a simple QA system for web apps

With using docker container, it can provide a QA system fast, easily, simply

But it has a limitation:

It's limited to only 1 container each feature branches

docker container

Limitation:Actual case:

A general web app is composed of multiple services ( API, DB etc..)




App

DB

API-2

API-1

Solution: add integration with docker-compose

Base OSS project: http://github.com/mookjp/pool

Run multiple containers each feature branches

Sample application

Python web app counts up visit times

docker-compose

Redis stores

visit timeslink

https://github.com/ainoya/pool/tree/docker-compose

app.pyfrom flask import Flask from redis import Redis import os app = Flask(__name__) redis = Redis(host='redis', port=6379)

@app.route('/') def hello(): redis.incr('hits') return 'Hello World! I have been seen %s times.' % redis.get('hits')

if __name__ == "__main__": app.run(host="0.0.0.0", port=80, debug=True)

Ref: https://docs.docker.com/compose/

https://docs.docker.com/compose/

docker-compose.yml(.erb)

web: environment: GIT_COMMIT: "<%= @git_commit_id %>" build: . ports: -‐ "80" links: -‐ redis redis: image: redis

DEMO https://github.com/ainoya/pool/tree/docker-compose

Set up QA environment each "master", "development" branches

Python web app

counts up visit times

http://master.pool.dev

Redis stores

visit timeslink

Python web app

counts up visit times

http://development.pool.dev

Redis stores

visit timeslink

http://development.pool.dev

Future plan

• Support efficient pattern shares some resources (DB, etc...) between same applications

• More integration with other solutionsECS, GKE/k8s,…

• Integrate with docker registry 2.0 system

And We're hiring :-)
