📖 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.

🥋 Sensei Says:

"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."
