Pair programming generally involves two programmers working on a single change from start to finish. You can augment this pattern by adding a test specialist, so you can test-drive feature changes first and the tester can ask questions and guide test and code design. What you get is quality built in from the start.

Because automation, AI, and agile have changed how we test software, the thought is that testers need to understand a certain amount of coding so that they can make themselves more well-rounded and better able to adapt within a software project. But there are other things testers can focus on before learning to code.

If a development team does pair programming, where does testing fit in? You don't have to wait until the programming is done—testers can be part of the whole process, from code design to reviewing changes to production. Pair programming plus a good automation strategy mean quality is built in throughout development.
