Agenda
Jenkins: an intro
Why use it
Installation on a Ubuntu machine
Testing
Jenkins: a complete solution
Jenkins is an automated continuous integration server
Automated testing, building, mantaining your code
Enforce quality control
Manage release process continuos delivery
Jenkins: facts
Written in java
600+ to customize Jenkins in every aspects
1000+ public repositories in Github
500+ contributors
Free and open source
Widely used tools for maintaing continuos integration cycle
Non java languages supported
Python
Ruby
PHP
Node.js
..
Why Jenkins?
Testing, building, maintaining, doing releases by hand is error
prone
promote test driven development reduce surprises
frequent deployment
Find bugs quickly
Jenkins
Easy to install, upgrade and configure
Monitor external tools
No limit of number of jobs
Lots of external tool to explore
Continuous integration
is the practice of merging all developer working copies with a
shared mainline several times a day. Its main aim is to prevent
integration problems- wikipedia -
Continuous delivery
is a software development discipline where you build software in
such a way that the software can be released to production at any
time.
Youre doing continuous delivery when:
Your software is deployable throughout its lifecycle
Your team prioritizes keeping the software deployable over
working on new features
Anybody can get fast, automated feedback on the production
readiness of their systems any time somebody makes a change to
them
You can perform push-button deployments of any version of the
software to any environment on demand-

Install on an Ubuntu server
wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key
| sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/
> /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins
Link between Django and jenkins
Apt-get install python-pip
Pip install django-jenkins
Pip install virtualenvwrapper
Pip install django
Configuring django project
Add 'django_jenkins' to your INSTALLED_APPS list
$ ./manage.py jenkins
JENKINS_TASKS = ( 'django_jenkins.tasks.run_pylint',
'django_jenkins.tasks.with_coverage',)
Testing web apps
Sometimes is a complex task,
a Web application is made of several layers of logicHTTP-level
request handling,
form validation and processing,
template rendering.
The Djangos way
Unittest: module built in to the Python standard library
Nose framework: uses custom test loader causes troubles with
Django code
django-discover-runner requires Django 1.4 built-in in Django
1.6
django-discover-runner
add a test_settings.py file to your app package
django-admin.py test --settings=myapp.test_settings myapp
Quality managment
Continuos performance testSelenium
Graphite
Cobertura
Best practices
Plan disk usage
Do distribute builds
Discard old build records to keep Jenkins status healthy
