Benefits of Dockerizing your testing

Why Docker?

• Docker accelerates your workflow

• Developing apps today requires so much more than writing code.

• Complexity:

• Multiple languages

• Frameworks

• Architectures

• Interfaces

Incredible adoption in just 4 years!

Docker Benefits• Agility

• Portability

• Security

• Cost savings

Why Docker is Hot!• Its simple

• Developers love it

QA best practice in

using Docker environments

Historical limitations of app deployment

• Slow

• Costs

• Wasted resources

• Difficult to scale

• Difficult to migrate

• Vendor lock in

Unlocking Containers

• A standardized unit of software that allows developers to isolate their app from its environment

• De facto standard to build and share containerized apps

• For Quality assurance:

• Clean builds

• Separate sections

• Base image

• Child image

• Containers

• Docker daemon

• Docker client

• Docker hub

Docker Architecture

Containers as a Service

Docker CLI – Common / useful commands

• docker build : build docker image from Dockerfile

• docker run : run docker image• docker logs : show log data for a running

or stopped container

• docker ps : list running docker containers (analogous to ps)

• docker ps –a : list all containers including not running

• docker images : list all images on the local volume

• docker rm : remove/delete a container | docker rmi : remove/delete an image

• docker tag : name a docker image

• docker login : login to registry

• docker push/pull : push or pull volumes to/from Docker Registries

• docker inspect : return container run time configuration parameter metadata

How to integrate

SonarQube for code coverage

Tracking and improving

software quality with

Overview

● Code quality (what, why

and when)

● SonarQube introduction

● How does it work?

● Integration with Maven

Project.

What is code quality?

“It’s an indicator about how quickly

developers can add business value to

a software system”

Why measure?

● Source code is the heart of each system

● Developers don’t write new software. They

maintain “legacy” systems

● A system is (almost) never “finished”

● You can’t improve if you don’t measure

● Broken window theory

When you should measure?

● From project day #1

● Continuously

● Prevent vs post-actions

● Prioritize and plan

What SonarQube is?

● Free & open source “Code Quality Platform”

● Provides moment-in-time quality snapshots

● Gives trends of lagging and leading

indicators

● Tracks developers’ seven deadly sins (seven

axes of quality )

How does it work?

● Analyzes source code and byte code

● Computes hundreds of metrics

● Associates metrics with analysis

snapshots

● Shows the results in dashboards

and widgets accessible by any

browser

SonarQube for everything

● Initially developed only for Java projects

● Today supports over twenty languages

Open Source : C++, C#, Flex, Groovy, Android,

Javascript, PHP, Python, XML,

Web(xhtml, jsp , jsf, )

Commercial : ABAP, C, C++, Cobol, Natural, PL/SQL, Visual

Basic

… and for everyone

● For developers. Is my code “good”? How can I improve it?

● For testers / QA staff. Which parts of the system lack unit

testing?

● For architects. Is the initial design “broken”? How about

complexity?

● For managers. Give me the numbers!! Are we going up or down?

Sonar Integration with

Maven Project

● Download and install SonarQube from URL

● Define sonar properties, jacoco.exec file path,

sonar dependency plugins Jacoco-maven-plugin,

Maven-compiler-plugin and maven-surefire-plugin)

● Push code coverage to sonar server using below

command from local/jenkins

mvn clean install sonar:sonar -

Dsonar.host.url=http://10.80.200.8 -

Dsonar.jacoco.reportPath=target/jacoco.exec

Understand Docker driven

test automation

Test Automation Pre Req’s

● Docker Setup

● Sonar Integration with Maven/Gradle.. etc.

● Jenkins Job creation with Docker Swarm Cluster

for Unit / Integration Testing.

● Run the job and get the code quality report

through email.
