Extreme programming (XP) is a software
development methodology which is
intended to improve software quality
and responsiveness to changing customer
requirements. As a type of agile software
development, it advocates frequent
"releases" in short development cycles,
which is intended to improve
productivity and introduce checkpoints
at which new customer requirements can
be adopted.

Other CI Solutions

@stablekernel
Alternatives to TravisCI

@stablekernel
• Similar to a managed full stack Travis CI Setup
• Includes TestFlight like beta environment
• Compatible with:
• BitBucket
• GitHub
• GitLab

@stablekernel
• Continuous Integration + Deployment Platform
• Conﬁguration through circle.yml
• Integrates with:
• GitHub
• Bitbucket
• GitHub Enterprise

@stablekernel
Xcode Server:
• Self Hosted
• Has been problematic in the past
• Integration with GitHub problematic

@stablekernel
• Self Hosted
• Not always up to date
• Relying on single open source project?!

@stablekernel
Conclusion
Why do we do all of this?
