We talk with Devon Estes, the creator of a new Elixir mutation testing library called Muzak. Devon joins us to explain what mutation testing is and how it can help development teams in organizations move faster and with greater confidence. We cover when a project can benefit from it, the challenges of offering a PRO version of a library, where Muzak is going in the future, and more!
