FISL 2010: CruiseControl: the open source that changed the way we develop software
Download as PPTX, PDF0 likes617 views
This document discusses the history and impact of CruiseControl, an open source continuous integration tool. It describes how CruiseControl originated from Martin Fowler's article on continuous integration in 2000. This allowed developers to automatically build software and run tests anytime code was committed. CruiseControl became widely adopted and helped popularize continuous integration as an agile practice. It now has over 600,000 downloads and supports many version control systems and programming languages. CruiseControl played a key role in changing how software is developed through continuous testing and integration.

- 2. Agenda
- 5. Motivation
- 6. Traditionally, different modules are developed by different teams/developers
- 7. In XP, any programmer can change any part of the code
- 8. Definition
- 9. Continuous Integration is a software development practice where members of a team integrate their work frequently…
- 10. … each integration is verified by an automated build …
- 11. … detect integration errors as quickly as possible…
- 12. … assumes a high degree of tests.
- 13. Demonstration
- 14. Solution: continually integrate and test throughout the projectDevelopersContinuous Integration ServerSource Repository
- 15. Developers check out code into their private workspaces
- 16. Developers work on functionality and validate it by running unit tests and local build
- 17. Developer update code to avoid conflicts
- 18. Developers work on existing conflicts and validate them by running tests and local build
- 19. When done, they commit changes to the repository
- 20. The CI server monitors the repository andchecks out changes when they occur
- 21. The CI server builds the system and runs automated tests
- 22. The CI server releases deployable artefacts
- 23. The CI server assigns a build label to the version of the code that it just built
- 24. The CI server informs the team of the successful build and generates useful metrics
- 25. If the build or tests fail, the CI server alerts the team
- 26. The team fix the issue at the earliest opportunity
- 27. Continually integrate and test throughout the project
