Benefits of Continuous Integration
- Removes integration sessions
- Minimizes number of integration bugs
- If you build and test your software once an hour, no problem is more than an hour old.
- Improves team work
- Delivers latest best build product
- Reduces the overall development cost by:
- making it easier to find and fix problems
- provides valuable and timely information, letting the development be managed more tightly.

- Refer to the original article on CI by Martin Fowler and Matthew Foemmel: http://www.martinfowler.com/articles/continuousIntegration.html
- Mike Clark's "Dear Manager" articles at http://www.clarkware.com/cgi/blosxom/DearManager give further information about the return on investment.
Success Factors
- Single source code repository
- Automated build scripts
- Automated tests
- Developers' discipline
- Synchronise often
- Don't break the build
- When you break the build, fix it.

Successful Build Defined
- All the latest sources are checked out of version control
- Every file is compiled from scratch
- The resulting files are linked and deployed for execution
- Suite of tests is run against the system
- If every test passes, then there is a successful build

What is CruiseControl? (Part 1)
- Free and open source build scheduler
- Consists of two components:
- Build loop (runs as a service/daemon)
- Status Dashboard (runs as web application)
- Works with many version control systems (CVS, PVCS, Subversion, ClearCase, ...)
- Works with any build tool that produces parseable output (Ant, Maven, ...)

What is CruiseControl? (Part 2)
- Cross platform (written in Java)
- Easily extensible:
- Configuration easily extended by custom plugins
- Well defined interfaces for version control systems, build tools and publishers
- Well supported:
- Complete reference documentation
- Active users mailing list
- Numerous tutorials
- "Pragmatic Project Automation" book by Mike Clark

How Does CruiseControl Work?
- Developer checks work into version control
- CC polls version control
- If CC detects any changes, it...
- triggers a build
- captures logs and build artifacts
- Examples: jar, war, javadoc, unit test report, code coverage report, code quality metrics
- publishes results
- Examples: send email, send instant message, turn on lava lamp
