3. What is Continuous Integration?
   • Continuous integration (CI) implements continuous processes of
   applying quality control — small pieces of effort, applied frequently.
   • Quality control as a continuous process - in small chunks
   rather than at the end of a development cycle / iteration.
   • Merging of smaller manageable change sets instead of large ones.

4. Important Ingredients
   • Version Control Software for your source code (Git, SVN, Darcs).
   • Self-Testing Code. (eg. Unit Tests, BDD, Selenium)
   • Agreement on Agile processes to adopt (in your team).
   • Bonus:
   • Project Management Tool. (eg. Pivotal Tracker, JIRA)
   • Branching Strategy (for development & deployment)

5. Continuous Integration in Action
   • Checkout mainline from code repository.
   • Write tests. Fail tests. Write Code. Pass tests. Refactor. (TDD, BDD)
   • Commit locally. Pull changes. Resolve merge conflicts.
   • Run full suite of tests locally. Push commits to server.
   • CI runs automated tests & builds. (If fail, fix it ASAP)

6. Getting the most out of CI
   • Keep stories small & granular (smaller change sets).
   • Merge early, merge often.
   • Reduce the pain of resolving conflicts later.
   • Write tests that runs fast.
   • Use Mocks and test doubles as much as you can.
   • Automate, Automate, Automate. (or one click action).

7. What is Jenkins CI?
   • Application that monitors executions of repeated jobs, such as
   building a software project or jobs run by cron.
   • Building/testing software projects continuously.
   • Monitoring executions of externally-run jobs.

8. What is Sonar?
   • Sonar is an open platform to manage code quality. As such, it covers
   the 7 axes of code quality:

    Bergmann (of PHPUnit fame)
    • Kitchen sink of Quality Assurance tools.
    • Build automation with Apache Ant.

11. QA Tools for PHP
    • Checkstyle (for processing
    PHP_CodeSniffer logfiles in
    Checkstyle format)
    • DRY (for processing phpcpd logfiles
    in PMD-CPD format)
    • PMD (for processing PHPMD
    logfiles in PMD format)
    • JDepend (for processing
    PHP_Depend logfiles in JDepend
    format)
    • xUnit (for processing PHPUnit
    logfiles in JUnit format)
    • Violations (for processing various
    logfiles)
    • Clover PHP (for processing
    PHPUnit code coverage xml output)
    • HTML Publisher (for publishing the
    PHPUnit code coverage report, for
    instance)
    • Plot (for processing phploc CSV
    output)
