Runtime Monitoring vs Manual Testing

Developers should learn runtime monitoring to ensure application reliability, performance, and security in live deployments, as it helps identify bottlenecks, failures, and anomalies that are hard to replicate in testing meets developers should learn manual testing to gain a user-centric perspective on software quality, catch edge cases early in development, and perform exploratory testing where automation is impractical. Here's our take.

Runtime Monitoring

Nice Pick

Developers should learn runtime monitoring to ensure application reliability, performance, and security in live deployments, as it helps identify bottlenecks, failures, and anomalies that are hard to replicate in testing

Pros

• It is essential for modern DevOps and cloud-native applications, where continuous monitoring supports incident response, capacity planning, and user experience improvements
• Related to: observability, logging

Cons

• Specific tradeoffs depend on your use case

Manual Testing

Developers should learn manual testing to gain a user-centric perspective on software quality, catch edge cases early in development, and perform exploratory testing where automation is impractical

Pros

• It's particularly valuable for usability testing, ad-hoc bug hunting, and validating new features before investing in automation scripts, helping ensure software meets real-world expectations and reducing post-release issues
• Related to: test-planning, bug-reporting

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Runtime Monitoring is a concept while Manual Testing is a methodology. We picked Runtime Monitoring based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Runtime Monitoring wins

Based on overall popularity. Runtime Monitoring is more widely used, but Manual Testing excels in its own space.
