We'll illustrate how we can use static analysis tools to drive the refactoring of a Rails app.
First, we'll quickly introduce static analysis, its benefits and complimentarity with other practices. We'll present each tools, how to understand them, and how they can drive the refactoring on a real big open source project. We'll show how to automate their run and integrate it in your workflow. Finally, if we get the time, we'll do the same on projects of the audience.
