Core Web Vitals Uncovered: A Tester’s Role in Web Performance Success
Friday May 16, 2025 14:50 - 15:30 EEST
BlackBox
In an era where speed and seamless interactions define digital success, website performance can make or break the user experience. Core Web Vitals (CWV), a standardized set of performance metrics defined by Google, have become essential for measuring web quality from a user-centric perspective. This session will introduce the three CWV—Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS)—highlighting their direct impact on both user satisfaction and business outcomes.

Designed specifically by a software tester with extensive experience in CWV, this talk will uncover why CWV are critical in  web application quality strategies, demonstrating how they expose performance bottlenecks often overlooked during development and testing. Attendees will gain useful insights into measuring and analyzing these metrics using tools like Lighthouse, PageSpeed Insights, and Real User Monitoring (a technique that captures actual user interactions to assess real-world performance).

Beyond the theory, this session will provide actionable guidance on integrating CWV into your testing pipelines, reporting performance issues with more detail and clarity, and collaborating effectively with developers to drive meaningful improvements. Whether you're new to performance testing or seeking to expand your expertise, you'll leave equipped with practical techniques to embed performance accountability into your quality culture.

Key Takeaways:
  • Core Web Vitals Help to Quantify the Web Performance Quality
    • Metrics like LCP, INP, and CLS directly measure the user’s experience with loading speed, responsiveness, and visual stability.
    • Good performance enhances user satisfaction, retention, and even SEO rankings.
  • Software Testers Play a Critical Role in Helping to Discover Performance Issues
    • Testers can identify performance risks early by integrating Core Web Vitals checks into their test plans, CI/CD pipelines, and monitoring.
    • Performance testing isn’t just a developer’s task—collaboration between testers and developers drives a shared quality mindset.
  • Practical Tools Make Performance Testing Accessible to Testers
    • Tools like Lighthouse, PageSpeed Insights, and Real User Monitoring simplify measuring Core Web Vitals.
    • Testers can track, report, and prioritize performance issues alongside functional defects for a more complete quality strategy.
