Performance Monitoring vs Manual Testing

Developers should learn performance monitoring to proactively identify and resolve issues that impact user experience, such as slow page loads or high latency, which can lead to customer churn and revenue loss 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.

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
