The Love Triangle
o DevOps = Marriage of Development and Operations
o Where does the Testing Team fit in the definition?
o Testing teams need to assert themselves to fit in all phases of DevOps
@muktaaDevOps@WhiteHedge.comWhiteHedge
Testing in all phases
o Pre-flight testing
o Unit Testing
o Functional Testing
o Integration Testing
o Nightly and Weekend Regression Tests
Test Early.Test Faster.Test Often.Automate.
@muktaaDevOps@WhiteHedge.comWhiteHedge
Testing Maturity
o Key differentiator of best devops infrastructures
o Vital part of devops process
o Test orchestration and automation is still a challenge
o Verify the changes. Verify them fast.
o Test code changes and if they integrate them well
o Ensure changes do not blow up the product!

The ChallengeEarly, Frequent and Accurate Testing requires access to real world testing environments.
Service Virtualization in the form of
Containerization, specifically using Docker,
intends to solve this problem.
@muktaaDevOps@WhiteHedge.comWhiteHedge
What is Docker?
Linux Container3 Components:
Docker Engine
Docker Hub
Docker Images
Benefits:
Speed
Portability
Density
Open Source
“Can create lightweight,
self sufficient containers
from any application”

Even after

For every
deployment, the Env

Shippable makes this dockerdeployment and thus testing,
simple
@muktaaDevOps@WhiteHedge.comWhiteHedge
Shippable
o SaaS Platform
o Reduces the time taken for code to be built, tested and deployed to production
o Shippable CI/CD
o Shippable Formations
@muktaaDevOps@WhiteHedge.comWhiteHedge
Shippable Formations
o Easy way to provision, configure, and deploy multi-container Dev and Test clouds (environments)
o Fully integrated with the updated Shippable CI/CD platform, and together, they create an automated, frictionless pipeline from source control to full-topology environments
o Can mimic your production environment or represent any combination of software component versions you'd like to deploy.
@muktaaDevOps@WhiteHedge.comWhiteHedge
Shippable Formations (Contd.)
Fully orchestrated,
persistent, and 'smart',
i.e. they can
automatically update
themselves when any
new code is committed
into any component of
the application.
Ensures that your Dev
and Test labs always
run the latest code and
are reliable indicators of
how that code will
behave in production.
@muktaaDevOps@WhiteHedge.comWhiteHedge
Notice the services under each env, the docker image and how it is mapped.
@muktaaDevOps@WhiteHedge.comWhiteHedge
Why Formations?
o Automation without scripts
o Automated integration/functional testing
o One-click upgrade and rollback
o No more 'works on my machine' bugs
o Developer-focused approach
o Cost effective
@muktaaDevOps@WhiteHedge.comWhiteHedge
LighthouseIt is a docker image watcher. You can add any image from any
registry that you want to track and get notified via email when
there is an update.
