The Power of Pair Programming

· Agile Zone

Discover how to increase change awareness, code quality, and maintainability through straightforward code reviews, with a simple, lightweight workflow, brought to you in partnership with JetBrains.

Some weeks ago I started practicing pair programming with some co-workers for two reasons:

  1. code some tasks of an user story
  2. get familiar with a new software code base

I haven’t had an opportunity to put this technique in practice a lot before, but I can say it was extremely important and beneficial for the project. Sometimes I was the driver and sometimes I was the observer. The driver is the person who starts coding and the observer is who starts doing the code review. That point is important: code review.

Pair programming encourages the review of the code. Perhaps you won’t have an opportunity to refactor some code as you have when you are pairing with someone. I think code reviews are important because:

  • Reviews increase code quality, because there are 2 people thinking about the same task at the same time.
  • Refactoring areas arise in the design where improvements are needed
  • When you have the strong support of an IDE (as Eclipse), a lot of refactorings (extract method, extract class, introduce parameter, etcetera) are highly automated, it helps keep code clean and maintainable
  • More code is read than written, two people reading the code can understand a lot more about the code base
  • New ideas arise because of different point of views
  • Questions can be solved by the sum of knowledge of the code base

And you? What’s your experience with pair programming?
