Scaling a team Test your code! Testing was the hardest part for us. The payoffs in catching regression bugs and conﬁdence in our deployments was well worth it

Slide 51

Slide 51 text

Is your code testable? If unit testing is hard, your code may not have been written to be testable.

Continuous Integration Continuous Delivery

Slide 55

Slide 55 text

Continuous Integration Frequently integrate code changes into the existing code repository Merging branches to master/production Automated build tests to ensure issues found quickly Does not have to be deployed

Slide 56

Slide 56 text

Continuous Delivery Produce valuable changes in code in short cycles to be released at any time. AKA: Continuous Deployment Automated build tests to ensure issues found quickly Deployment happens on successful build

Slide 57

Slide 57 text

Which is right for you? Your goal should be Continuous Integration (at least!) Strive for Continuous Delivery if it makes sense Applications with a live event component may not be suited for Continuous Delivery
