Is Continuous Testing really just
one phase in DevOps?

7. @muktaaDevOps@WhiteHedge.com
DevOps is actually all about
Continuous Testing!

8. @muktaaDevOps@WhiteHedge.com
The Love Triangle
• DevOps = Marriage of
Development and
Operations
• Where does the Testing
Team fit in the
definition?
• Testing teams need to
assert themselves to fit
in all phases of DevOps

9. @muktaaDevOps@WhiteHedge.com
Testing in all phases
• Pre-flight testing
• Unit Testing
• Functional Testing
• Integration Testing
• Nightly and Weekend Regression Tests
Test Early.
Test Faster.
Test Often.
Automate.

10. @muktaaDevOps@WhiteHedge.com
Testing Maturity
• Key differentiator of best devops infrastructures
• Vital part of devops process
• Test orchestration and automation is still a
challenge
• Verify the changes. Verify them fast.
• Test code changes and if they integrate them well
• Ensure changes do not blow up the product!

The Challenge
Early, 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.

12. @muktaaDevOps@WhiteHedge.com
What is Docker?
Linux Container
3 Components:
Docker Engine
Docker Hub
Docker Images
Benefits:
Speed
Portability
Density
Open Source
“Can create lightweight, self
sufficient containers from
any application”

Virtual Machine Docker
Docker is not a VM

Nightly Builds –

Even after
successful tests, the

For every
deployment, the Env
has to be setup

Shippable makes this
docker deployment and
thus testing, simple

17. @muktaaDevOps@WhiteHedge.com
Shippable
•SaaS Platform
•Reduces the time taken for code to be
built, tested and deployed to production
•Shippable CI/CD
•Shippable Formations

Shippable Formations
• Easy way to provision, configure, and deploy multi-
container Dev and Test clouds (environments)
• Fully integrated with the updated Shippable CI/CD
platform, and together, they create an automated,
frictionless pipeline from source control to full-topology
environments
• Can mimic your production environment or represent any
combination of software component versions you'd like to
deploy.

23. @muktaaDevOps@WhiteHedge.com
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.

Why Formations?
• Automation without scripts
• Automated integration/functional testing
• One-click upgrade and rollback
• No more 'works on my machine' bugs
• Developer-focused approach
• Cost effective

Lighthouse
It 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.
