After a few years of working as a software engineer, I developed an interest in the concept of code quality - and the ability to place better guarantees on the work coming out of the development team using automated unit testing. As an individual, I can demonstrate that my code is testable, and executes given functional requirements within certain parameters across different platforms and conditions. As a team, existing and introduced bugs can be readily identified and corrected much more efficiently, and ensure that corrected behaviour remains in place for future releases. When mixed with a bit of agile development exposure, I found myself in the world of TDD, BDD, Continuous Integration and Continuous Deployment, not to mention the opportunity to use some cool technologies like TeamCity, Selenium, and even some physical red/green build lights. Commit/build issues that previously took a day or more to find could now be discovered and fixed much more efficiently, before the developer had moved on from the code, and before anyone else got a hold of the broken build! I believe that agile development methodologies, combined with continuous integration and testing strategies assisted us in achieving these goals. Well-defined functionality and architecture supported by a thorough testing framework, both automated and human-based, helps us to get high-quality products out the door.
