Jenkins-CI with perlbrew on OSX
Continuous Integration (CI) is the autotesting of unit tests.
There are many good answers. First and most importantly, developers get fast notification of when and where defects were committed to the source code repo. Testing on multiple platforms and environments also becomes possible and automatic. Invoking a unit test build manually is silly when we have computers. Let's be smart and lazy.
Jenkins is a fork of Hudson. It's open source, free, and mature. Polyglot; it'll test language. Network farm architecture. Plugins for everything.
This build will set up a sane Jenkins on OSX against gitolite with notification via IRC and Growl and metrics via Dashboard View.
I use perlbrew. This build will also show you how to configure tests using a perlbrew's prove(1).
- Install from package from http://jenkins-ci.org/ (don't use
brew install jenkins- it's old)
- cpanm -S Task::Jenkins

Configure Jenkins Git user
Instructions at https://wiki.jenkins-ci.org/display/JENKINS/Gitolite
- Create ssh-key for user jenkins.
- Copy to gitolite-admin/keydir/ as jenkins_rsa.pub
- Add jenkins_rsa to readonly users in gitolite-admin/conf/gitolite.conf
- git commit -am 'Add jenkins' && git push
Configure Global Security
Can plug into AD, LDAP, Redmine and more for authentication.
We use Active Directory in this land of Windows. Our settings similar to:
Domain Name: ads.example.com
Bind DN: CN=redacted,OU=Services,OU=Users,OU=Example Co.,DC=ads,DC=example,DC=com
Bind Password: redacted

Is there a way to use a file-change notifier (eg linux's inotify) instead?
Execute Shell | Add build step
source /opt/perlbrew/etc/bashrc perlbrew use perl-5.16.2@dev /opt/perlbrew/libs/perl-5.16.2@dev/bin/prove -r --timer --formatter=TAP::Formatter::JUnit -l t
If you don't need perlbrew, this should do the trick:
prove -r --timer --formatter=TAP::Formatter::JUnit -l t
Add post-build action: Growl
Growl IP: Your desktop IP
Also add passsword "Holla-At-Me" to System Preferences | Growl. This will permit other computers to send notifications to your Desktop.
This is more of a shared secret than a password. It will open your desktop up to Growl shenanigans from coworkers.
Add post-build action: IRC Notication
Channel Name: #ci
Notification Strategy: change
Dealing with Java heap errors on OSX
Problem: The Java Permgen pool would run out of memory and the app would stop responding.
Jenkins' heap allocations can be viewed by running
sudo jmap -heap $(pgrep -u jenkins java)
Fix: Submitted https://github.com/jenkinsci/jenkins/pull/828. This adds controls for Java heap sizing and working defaults on OSX.
