COMMON PROBLEMS WHEN SHARING SOURCE CODE Work’s on my machine syndrome Didn’t realize I need to test on that

version of ruby/node/etc. Pull requests - how do I know if

this will break the build? Would love run tests on commit,

but don’t have $$$ for equipment.

CONTINUOUS INTEGRATION...is the practice, in software engineering, of merging all developer working copies with a shared mainline several times a day.

~Wikipedia

...is a software development practice where members of a team integrate their work frequently

CONTINUOUS INTEGRATION CONTD. Once the code is built, all tests should run to confirm that it behaves as the developers expect it to behave.

~Wikipedia

...verified by an automated build (including test) to detect integration errors as quickly as possible...

QUOTESWhat Github did for sharing code, Travis CI will do for testing code

- Brian Ford, Rubinius, @brixen

I'm sure there was life before @travisci, but I choose to ignore it.

- Jeff Casimir, Jumpstart Lab/Hungry Academy @j3

I have used many CI systems, but Travis is the most awesome one so far!!

AUTO DEPLOYMENTWhy start trusting a human now?

Sunday, January 12, 14

CONTINUOUS DEPLOYMENTIn the same vein the practice of continuous delivery further extends CI by making sure the software checked in on the mainline is always in a state that can be deployed to users and makes the actual deployment process very rapid.

~Wikipedia

A natural consequence of this is that you should also have scripts that allow you to deploy into production with similar ease.
