The document presents a case study on continuous integration (CI), highlighting its importance in addressing developers' and QA's dilemmas regarding build and deployment processes. It discusses the benefits of CI, such as early issue identification and efficient test automation, along with recommended practices and various tools like Hudson CI and its setup for distributed builds. The case study emphasizes the advantages of adopting CI for improved code quality and streamlined development workflows.

1. Continuous Integration: A case study Vaibhav Kothari Talentica Software (I) Pvt ltd

2. Abstract Developer’s dilemma QA’s dilemma Continuous Integration ? Case study What is accomplished ? Benefits of CI Recommended Practices Other Tools Available Q&A

3. Developer’s dilemma Will my changes integrate successfully with all versions of code? How much time/effort it will take to build and deploy from different source repository branches? Why can’t QA take this up!!

4. QA’s dilemma How much time/effort it will take to build and deploy from different source repository branches? How much time/effort will it take test builds from different sources? I can't build that often!

5. Continuous Integration ?? As wiki says “ Continuous integration involves integrating early and often, so as to avoid the pitfalls of " integration hell ". The practice aims to reduce rework and thus reduce cost and time.”

6. Continuous Integration….

7. Continuous Integration…. Integrating the build process with continuous development. Concurrent build preparation from different branches. Integrating build system with deployment and test automation. Monitoring build and test.

8. CI in agile development

9. Case Study Current Product development Lifecycle

10. Case Study Where does integration server stands ?

11. Features to look out for Basic Continuous Integration Build Triggering options Support for tools Set ups and usability Build logs and metrics Notifications Plugins, Extensions Case Study

12. Hudson CI Open source tool available as deployable war file. Each build and deployment process can be set up as a separate project and run concurrently or subsequently. Supports distributed builds The most used CI server in an informal developer survey! Case Study

13. Case Study Tools to be Integrated Windows XP/Linux OS Selenium RC Test Automation Apache Tomcat 6.0 Web server Apache Ant Build Tool Sub version Version control Hudson CI Continuous Integration

14. Case Study… Setting up a build Job

15. Case Study….. Defining build triggers

16. Post build tasks Automate build and deployment process and server restart. Integrate Hudson with test automation suite Remote deployment of multiple builds and test suite invocation Case Study

17. Case Study… Post build tasks

18. Distributed Builds Build distribution using Single Hudson installation. Single click using Master/Slave mode. Concurrency in largely distributed projects. Case Study

19. Case Study… Building Remotely

20. Case Study… Slave set up in Hudson

21. Case Study…. What’s achieved?

22. Nobody minds it! Single click process. Early identification of build issues. Early identification of bugs. Incremental development. Constant availability of sane build. Efficient use of Test Automation. More time for Quality improvement. Benefits of CI

23. Maintain a code repository Automate the build and Deployment Make your build self-testing Everyone commits every day Every commit (to mainline) should be built Keep the build fast Test in a clone of the production environment Make it easy to get the latest deliverables Everyone can see the results of the latest build Recommended Practices
