2. Continuous Integration Definition A software development practice where members of a development team regularly merge and commit their changes into a mainline tree which is tested after each merge for errors. Goal Minimize integration complexity by working with small change sets and keeping a buildable and tested mainline tree which is available for deployment.

3. Process ● Update ● Changes ● Test ● Update ● Merge ● Test ● Commit ● Test Development Integration Verification

4. Benefits ● Simplified Integration ● Build Always Works ● Transparency

5. Best Practices ● Check in early, check in often ● Communicate commits with the team ● Do not write new code when the build is broke ● Don't let the build remain broken overnight ● Communicate broken builds with the team ● Only update when the build is working ● Everyone should understand the build

6. Checklist ✔ Source Version Control ✔ Build ✔ Testing ✔ Automation

7. Source Version Control Definition Database which stores revisions of files and allows retrieval of each revision. Common Features ● Diffing ● Branching ● Tagging Examples ● CVS ● Subversion ● Git

8. Build Definition A combination of scripts which compile programs, test the artifacts, and generate installers. Features ● Single Command ● Incremental Building ● Dependency Fetching Examples ● Make ● Ant ● Maven

9. Test Definition Exercising an application in a controlled environment with specified inputs and state, observing outputs and state changes, verifying correctness by a set of metrics. Types ● Unit ● Functional ● Integration ● System ● Performance ● Load Examples ● xUnit ● Selenium ● Fitnesse ● JMeter

10. Automation Examples ● CruiseControl ● Hudson Features ● Report Integration ● Web Interface ● Notification ● Distributed Definition A scheduled or triggered build which builds the software, runs tests, generates reports, and notifies the participants of the success or failure.

11. Advanced ● Staged Build ● Branch Per Feature
