In modern development, testing is no longer just at the end. Testers are expected to be involved both earlier (Shift-Left) and later (Shift-Right) in the software lifecycle. This topic can highlight:
Shift-Left: Early testing during requirements, design, and development (unit testing, static analysis).
Shift-Right: Testing in production with real user data (monitoring, chaos testing, feature toggles).
Benefits of combining both approaches for faster delivery and higher quality.
How testers can balance proactive prevention (Shift-Left) with reactive monitoring (Shift-Right).
This helps testers understand their expanded role in Agile/DevOps environments.
