Introduction
When software is being developed, it needs a safe place to be tested without affecting real users or live data. Setting up a test environment solves this problem by creating a controlled space where tests can run reliably and safely.
Imagine practicing a play on a stage that looks exactly like the real theater but is empty and safe. Actors can try out their lines and movements without worrying about an audience or mistakes. This practice stage helps them prepare perfectly for the real performance.
