Charly, remember that it's "code review guide", not "testing guide"

Some definitions about Agile

The Agile name is an umbrella for quite a lot of practices that range from programming, to testing, to project management and everything in between.

Agile has some key practices that could affect the way the code is reviewed.

Agile Development is well suited for code review, as two of its key practices are "pair programming" and "peer review". AD incorporates code review in itself, in what traditionally was seem as another phase.

Agile blurs the difference between developing and testing, and so does with code review. It is not an external activity.

Pair Programming

This technique is quite controversial, but when its adopted it has the benefits of making better code, as there is one programmer supervising cooperatively the other one's work. If both programmers know this guide, they will apply it continuously.

Peer Review

This one is enforced by the usage of tools like .... that ask another user for a code review before commiting to the versioning system.

Life Cycle

AD tries to keep the code review as near as possible to the development phase, there is no such thing as develop, test, code review cycle.

The role of testing

It is so fundamental, that the xDD pervades Agile, test first, test earlier

Continuous integration

it triggers the tests and often static code analysis too. it makes detection of integration problems arise very quickly.

Test Driven Development

It aims at code simplicity due to the need of making it testeable

Behavior Driven Development

....

Domain Driven Design

....

Refactoring

Refactoring is the art of changing the code with out changing its behavior. The problem is that thanks to the heavy testing, you can trust that the interface does not change, but behind it, the code can be very volatile. You have to review the code continously, another argument for peer review and automatic static analysis.

Code Reviewing an Agile Project

If you are going to review an Agile Team project code, the best thing that you can do is give this guide to that Team as early as possible and most of your work will be done for you.

In order to review an Agile Project, you will have to extend the review to the tests and ...
