Sandbox

A Sandbox is an isolated environment used to safely run, test, or experiment with software without affecting live systems, real users, or production data. It provides a controlled space where changes can be made, code can fail, and unexpected behaviour can be explored without risk outside the sandbox. For example, a team building an online checkout feature might use a sandbox version of their application to test new payment logic. In the sandbox, testers can create fake users, place dummy orders, and deliberately trigger errors like failed payments or timeouts without charging real customers or impacting the live website. Once the team is confident the change behaves as expected, it can then be safely promoted to production.
