One of the challenges faced by many web development based projects is the integration of source code for multiple releases during parallel development. The task to build and test the multiple versions of source code can eat out the quality time and limit the efficiency of the development/QA team. The case study focuses to resolve the issues of extensive effort consumed in build and deployment process from multiple branches in source repository and aim at Identification of source code integration issues at the earliest stage. This can further be enhanced to limit the manual intervention by integration of build system with test automation tool. The above can be achieved by using different CI tools (like Hudson/Bamboo/TeamCity/CruiseControl etc) for continuous build preparation and its integration with any test automation suite. The case study specifies the use of CI-Hudson tool for continuous integration using ANT tool for build preparation and further invoking the automation test suite developed using selenium. It also discusses the limitations and challenges of using such an integration system for testing a web based application deployed on Apache Tomcat server. It also details additional plugins available to enhance such an integration of multiple systems and what can be achieved using the above integration.
