Demystifying Code Reviews

Most people might agree, that reviewing code is a nice idea. But in the next sentences you'll most likely hear arguments like: "there is simply no time, it blocks us, nobody else knows the domain well enough and the tools are horrible, man!"At mobile.de we have been through a lot of different code review approaches, dead-ends and tools. In this talk Mateusz Szczap and Holger Hammel from mobile.de would like to present some insights about how reviews could work and a way how you can do effective code reviews using gerrit.

Gerrit is a free and web based system that facilitates code reviews underneath using Git as a revision control system.Apart from basics tasks that Gerrit can handle such as showing differences in a two side panels, adding comments to lines of code or the whole review – Gerrit allows to a-u-t-o-m-a-t-e everyday work in such a manner that creating a Gerrit review is as simple as a git commit and push commands.This in turn shortens time to create a review comparing to other solutions on the market as reduces a pain factor and necessity to context switch to create a code review.
