• Continuous Integration:

• Team members integrate their work daily

• All the components are automatically integrated and tested by the CI system

What is CI and CD?

• Continuous Delivery:

• Is the advancement of CI

• Is an end-to-end approach (from dev to end user)

• Software is always in a production-ready state

• It is the technique to automate the

build, test and deployment process

• Fail Fast pattern

• Pipeline Pattern from Jez Humble&Co.

• Continuous Deployment:

• Continuously deployment to the Production environment (one-click idea)

Why

© Unic - Seite 11

• Forces us to write Quality software

• The overall Thinking changes from

dev -> test system to dev -> end user system

• Faster release cycles are possible

• Automated Software Development Process is less error prone

• Team Ownership of the release process (not only «Release Manager»,

infrastructure is also code)

• Everybody can do a release (one click)

• With Maven Plugins: Auto start/stop of CQ, deployment of CQ packages over the

CRX HTTP interface

• Running auto. tests with JUnit and HtmlUnit

• Set of unit and integration tests

• Automated Acceptance tests still in progress

Foundation: CI

• Separate “delivery” and “infrastructure” Maven module

• Delivery:

• Deployment scripts

• Infrastructure

• Environment-specific configurations

• Done with Ant scripts and custom Ant tasks

Next: Continuous Delivery

© Unic - Seite 15

• Direct deployment to the customer's production environment

• Example: Trusted Maven Repositories
