- 7. CI – Benefits • Immediate bugdetection • No integration step in thelifecycle • A deployable system at any givenpoint • Recordofevolution ofthe project
- 8. CI – The tools • Code Repositories • SVN, Mercurial,Git • ContinuousBuild Systems • Jenkins,Bamboo,Cruise Control • TestFrameworks • JUnit,Cucumber,CppUnit • Artifact Repositories • Nexus,Artifactory,Archiva
- 9. Jenkins Branched fromHudson Java basedContinuousBuild System Runs in servletcontainer Glassfish,Tomcat Supported byover 400plugins SCM,Testing,Notifications,Reporting, ArtifactSaving,Triggers,External Integration Underdevelopment since 2005 http://jenkins-ci.org/
