Shift-Left & Shift-Right Testing: A Balanced Approach to QA
🔄 Shift-Left Testing:
- Focuses on early defect detection by integrating testing at the beginning of the SDLC.
- Prevents issues rather than fixing them later, reducing costs and improving software quality.
- Uses practices like unit testing, static code analysis, and CI/CD automation.
🔄 Shift-Right Testing:
- Involves testing in production to monitor real-world performance and user experience.
- Uses techniques like canary releases, A/B testing, and chaos engineering to ensure stability.
- Helps identify post-deployment issues that may not surface in traditional testing.
📌 Why does it matter? A combination of both ensures faster, more reliable, and high-quality software delivery by preventing defects early and continuously monitoring performance in production.
