Mistakes happen, right? You strive to catch configuration issues before systems are deployed, but they creep in and reappear, especially with manual delivery methods. There's an answer, though — you can boost the effectiveness, efficiency and coverage of testing by adopting automation.
Puppet Enterprise lets you test changes before you deploy them to production. This is possible because you define your infrastructure as code, which allows you to adopt agile development best practices, such as automated testing and deployment. Just like developers have test-driven development, your team can have test-driven infrastructure. Automation gives you the confidence of knowing your deployments will go as expected every time.
