What Is It?
Ever installed an app update and suddenly something that worked fine before is broken? That’s what Regression Testing prevents! It ensures that new changes don’t introduce unintended errors in previously working features.
Why Is It Important?
🔹 Ensures stability – Prevents new updates from breaking existing functions.
🔹 Reduces production issues – Detects problems before they affect users.
🔹 Supports Agile & DevOps – Continuous testing keeps software reliable.
Example in Action
A shopping app adds a new discount feature. Before release, regression testing ensures:
✔ Users can still add items to their cart.
✔ The checkout process remains smooth.
✔ The app doesn’t crash due to unexpected code conflicts.
Without regression testing, small tweaks could cause major headaches for users.
