Celebrating 1 year of Collaboration Driven Development (CDD)

If a developer takes the time to write and run unit test cases for his code, his goal is to deliver a better product. So you can ask yourself why we still need testers if all developers are doing unit testing. Because there is no way that a developer is able to come up with all of the test cases to verify when his code will fail. Developers are too attached to their code, and it is emotionally not possible to test the application for bugs.

A solution for this problem is the concept of TDD (Test Driven Development) where you get something working now and perfect this later. So why should testers care about TDD? Mainly because of the main activity within TDD: the creation of a unit test case before writing any ‘production’ code.

Like stated before the developer will need some help to come up with decent test cases and this will result in a closer and better collaboration between a tester and a developer. A new concept has been born namely Collaboration Driven Development (CDD). In CDD the tester will help the developer during the creation of their unit tests (with standard checklist or with a test condition brainstorm session) and the developers can help the tester understand the application more in detail.

I as a tester, I cringe when I see the crappy code has been shipped before toward the test and the production environment. Nowadays this crappy code is disappearing from the application and when a bug is reported by the testers we all know that is a good bug and not a bug which will go into the bug ping pong lifecycle. So this presentation will cover the concept of CDD together with the benefits and the disadvantages of this approach in order to show that when a developer take the necessary time to test his code with unit test cases it doesn’t mean that a better product is created.
