The traditional approach to testing and monitoring involves separating these two processes, which can lead to costly engineering time, sales, and customer confidence being lost when issues arise. This separation can result in a lengthy process of identifying and resolving problems, as seen in the example where a change to a universal button component caused issues with customers logging in or submitting payments. In contrast, uniting testing and monitoring through monitoring as code (MaC) enables continuous testing and immediate alerts for failures, reducing the impact of issues on engineering time, customer confidence, and sales. By integrating these processes, teams can respond quickly to problems, reduce finger-pointing between QA and Ops, and maintain a professional image for their customers.
