POSSIBLE AGENDA TOPICS
Introduction
CI – what is it, why do we use it, what are we trying to achieve
Automation / Code Quality
Tools
Unit tests
Cobertura
Sonar
E2E Tests
Selenium
Cucumber
Amazon cloud
Pipeline
Integrating mobile
Vagrant - Infrastructure as code
Management / organizational aspect

Your setup
How do you build software?

WHAT IS SO SPECIAL ABOUT AGILE?
6

WHAT IS IMPORTANT IN AGILE?
8

Agile
=?
Release working software anytime
9

Traditional waterfall model / tools do not support
“build and deploy anytime”
10

WHAT IS CI / CD?
CI and CD
=
Automated Build?
Automated Tests?
Automated Quality?
Automated Deployment?
Automated Feedback?
11

WHY CI / CD
Deliver value to the business more frequently
Better Quality
Early Bugs
Bug Prevention instead of late detection
Fast & frequent feedback
12

WHY CI / CD
Automated frequent builds
Automated frequent tests
Automated frequent code quality metrics
(Hopefully) Fewer bugs
Early feedback
Fast feedback
13

WITHOUT CI
Slow / long release cycles
Late testing
Waterfall (WaterScrum)
Bugs
Slow feedback
Complex integration
14

CORE PRINCIPLES
Every build could be a release
Everything should be automated
Stable and trustworthy automated tests
Build pipelines
15

CAN YOU MEASURE AUTOMATED CODE
QUALITY? DOES THAT MAKE SENSE?
20

AUTOMATED CODE QUALITY?
Sonar gives you information on:
- Lines of code
- % of comments
- Duplications
- Complexity
- Rules compliance
- Unit test coverage
- Unit test success rate
- Unit test duration
- Hotspots
21

WHAT ARE BARRIERS TO CI / CD?
24

WHAT IS CONTIUOUS INTEGRATION?
Continuous integration (CI) is the practice, in software engineering,
of merging all developer working copies with a shared mainline
several times a day. It was first named and proposed as part of
extreme programming (XP). Its main aim is to prevent integration
problems, referred to as "integration hell" in early descriptions of XP.
CI can be seen as an intensification of practices of periodic
integration advocated by earlier published methods of incremental
and iterative software development, such as the Booch method. CI
isn't universally accepted as an improvement over frequent
integration, so it is important to distinguish between the two as there
is disagreement about the virtues of each.
25

WHAT IS CONTINUOUS DELIVERY?
26
Continuous Delivery (CD) is a design practice used in software
development to automate and improve the process of software
delivery. Techniques such as automated testing, continuous
integration and continuous deployment allow software to be
developed to a high standard and easily packaged and
deployed to test environments, resulting in the ability to
rapidly, reliably and repeatedly push out enhancements and
bug fixes to customers at low risk and with minimal manual
overhead. The technique was one of the assumptions of
extreme programming but at an enterprise level has
developed into a discipline of its own, with job descriptions for
roles such as "buildmaster" calling for CD skills as mandatory.

THE MANAGEMENT / ORGANIZATIONAL ASPECT
What are the changes for developers and
testers?
What needs to be changed in the organization to
enable them to implement CI / CD?
What role has management in creating a devops
culture?

Apache Maven is a software project
management and comprehension tool. Based
on the concept of a project object model (POM),
Maven can manage a project's build, reporting
and documentation from a central piece of
information.

POM.XML
The pom.xml file is the core of a project's
configuration in Maven. It is a single
configuration file that contains the majority of
information required to build a project in just
the way you want.
38

MAVEN TARGETS
validate: validate the project is correct and all necessary information is available
compile: compile the source code of the project
test: test the compiled source code using a suitable unit testing framework. These tests should not
require the code be packaged or deployed
package: take the compiled code and package it in its distributable format, such as a JAR.
integration-test: process and deploy the package if necessary into an environment where integration
tests can be run
verify: run any checks to verify the package is valid and meets quality criteria
install: install the package into the local repository, for use as a dependency in other projects locally
deploy: done in an integration or release environment, copies the final package to the remote repository
for sharing with other developers and projects.
clean: cleans up artifacts created by prior builds
40

EXAMPLES
mvn clean
mvn compile
mvn test
