What is Regression Test?
Tests that verify previously working features still work after new changes are made.
Why It Matters
Regression tests catch cases where fixing one thing accidentally breaks another.
Real-World Example
Running the full test suite after adding a new feature to ensure existing features are not broken.
“Understanding terms like Regression Test matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
