📖 What is Root Cause?
A root cause is the fundamental reason for the occurrence of a defect or failure. Identifying and fixing root causes through root cause analysis helps prevent similar defects from occurring in the future.
"Fixing the defect solves the immediate problem, but addressing the root cause improves the process and prevents future bugs. This ties into the 'testing is context-dependent' principle."
