5. 5 Fail Early, Fail Fast, Fail Often.
6. Continuous Integration It is the practice of merging all developer workspaces with a shared mainline several times a day. 6 http://en.wikipedia.org/wiki/Continuous_integration
7. Continuous What? • Build • Test – Unit tests, integration tests… • Analysis • Feedback • Publish • Deploy • ... most tedious things! 7
8. What To Be Integrated? • People • Code • Environment • Report • Thought • ... everything valuable! 8

16. Personal Information • Child of Kohsuke Kawaguchi (川口耕介) • Renamed from Hudson – Had cosmetic surgery at the same time 16 portrait before the surgery
17. Skills • 耐操、有擋頭 – 不遲到、不早退 – 不會亂吠 • 專心 – 不會上 facebook, YouTube • 記性好 – 不會忘了改什麼設定，或忘了按 commit 就下班 • 便宜 17
18. Running Jenkins • Download – http://mirrors.jenkins-ci.org/war-stable/latest/jenkins.war • Run • Play around – http://localhost:8080/ 18 java -jar jenkins.war [--httpPort=8080] https://wiki.jenkins-ci.org/display/JENKINS/Starting+and+Accessing+Jenkins

24. CI Practices • Everyone commits at least once a day. • Keep the build fast. – An unit test is just an UNIT test. – Replace dependencies with mocks. • 100% of tests must pass for every build. • Fixing broken builds is of the highest priority. • Someone review reports generated by the build. 24 http://www.martinfowler.com/articles/continuousIntegration.html & Paul M. Duvall et al, Continuous Integration
