Switching to Test-Driven Development (TDD) on an existing project without tests presents special challenges. Code could be a tangled mess of dependencies that defeats the very concept of unit testing. Or somebody attempted TDD in the past and you have a test suite that needs to be fixed before any new tests can be written.

Published January 18th, 2010 Under Software Testing | Comments Off on Don’t Mock Yourself Out

Ask experienced Rails developers what they think about mock objects and some will say “absolutely awesome” while others “absolutely horrible.” The problem with both of those answers lies their “absolute”-ness. Used appropriately, mock objects are a powerful design tool that can lead to highly maintainable applications. Used in the wrong context or for the wrong reasons, they can lead to painfully brittle test suites that do little to maintain confidence in an application. In this talk, David Chelimsky will explore mock objects in the abstract and in the context of Rails.

Working Effectively with Legacy Rails Code

Published December 29th, 2009 Under Software Testing | Comments Off on Working Effectively with Legacy Rails Code

Rails has powered Oakley.com, a site generating tens of millions of dollars in revenue for the past two years. It has 80 models, an equal number of controllers, 75k lines of code…and no tests. I will talk about how we’ve been chipping away at growing an effective, valuable test suite since I’ve come on with Oakley. How can we take a mass of untested code that runs our businesses, and start working to the ideal of high-quality, malleable, tested code, while still meeting the demands of high productivity in our daily work? My talk will get people thinking and talking about that process, and give them practical techniques for making it reality
