1. 1. Build Process The beginnings of Continuous Integration
2. 2. Who Am I? CTO/Founder of Pamiris, Inc. Extensive NPO board service Overseen payroll conversions & HRIS implementations with over 600 employees BBA, MIS from EWU 2004 (manga cum laude, BGS)
3. 3. Build Process: wait... why? But PHP doesn't have to compile! definition - Build /bild/: The process of preparing software for deployment and/or distribution.
4. 4. PHP Deployment Prep Lint (syntax/compile error checking) SLOC (source lines of code) metrics Unit testing Code coverage analysis Functional Testing Code style checking Cyclomatic and N-path complexity Code duplication (DRY)
5. 5. PHP Deployment Prep: Again... why should we? Ability to track code quality trends More people/other teams can contribute safely(er. Saflier. Saferly?) Accountability for all Nervous sleep deprivation, anyone? Sooner found = cheaper fixed
6. 6. Quick Feedback Total coverage statistics Complexity measures CRAP index: Change Risk Anti- Patterns Pass/No Pass for tests
7. 7. PHP Deployment Prep: Why doesn't it happen? Never enough time It worked fine on my machine It didn't seem like a big deal If it isn't easy and repeatable, it won't happen.
8. 8. Build Automation: Make it easy, make it happen Developers and QA folks alike should be able to check a commit with absolute ease. The easier it is, the more it happens. The more it happens, the better the code is.
9. 9. Build Automation Tools GNU Make http://www.gnu.org/software/make/ Phing (PHing Is Not Gnu make) http://www.phing.info/ Apache Ant http://ant.apache.org/
10. 10. Start Simple Get PHPUnit, behat, PHPspec or other unit test running Get PHPLOC to run (composer makes it easy) Install a build automation tool MAGIC... ??? profit.
11. 11. Basic build.xml
12. 12. My current build.xml ~175 Lines Tasks: Build (prepare, lint, phpunit-ci, phploc, pdepend, phpmd) Build-parallel Phpcs (coding standard analysis) Selenium-install Selenium-start -stop
13. 13. Ant usage: running the build Just 'ant' will autorun the whole build command 'ant ' will run any part of it Different targets for different uses Developers WIP: fast unit tests w/o coverage or functional Developers pre-commit: all tests plus coverage Metric tracking: all static analysis tools Pre-deploy: all of the above
14. 14. Next Steps Flesh out other valuable build steps Store build results Automate build on check-in with Jenkins/TravisCI Add charting (trend display) Continuous deployment
