The Journey Towards Continuous Integration
The document discusses the journey of implementing continuous integration (CI) practices. It describes initial frustrations with ad hoc builds and lack of standards. A council was formed including managers and developers to address threats, opportunities and plan implementation. Automation tools were adopted, including Cruisecontrol, PHPUnit, phpDocumentor, PHP_Codesniffer, and others to enable automated builds, testing, documentation and metrics. Jenkins was later adopted for its improved installation, configuration and support for multiple languages. SonarQube was also used for continuous analysis and quality management. Implementing a CI culture involved adopting development models, scaling the build process, code reviews and improving communication.
