Why this topic matters
Legacy code powers critical systems, but it’s often fragile and risky to change. Many teams fear changing code because they can break production, leaving defects undetected until it’s too late.
By learning ATDD for legacy code, you’ll gain the skills to change code safely and catch regression bugs before they cause costly failures.
