# Performance Testing Basics

- Define SLO-aligned performance goals
- Run baseline, load, stress, and soak tests
- Analyze response time and error-rate behavior

# k6 for Practical Performance Checks

- Write JavaScript-based load scenarios
- Integrate runs into CI for regressions
- Use thresholds to fail builds on critical degradation

# Accessibility Testing Foundations

- Use WCAG as baseline standard
- Automate common checks with tools like axe
- Add keyboard and screen-reader manual checks

# Security Testing in QA

- Prioritize top web risks from OWASP
- Include misuse/abuse scenarios in test design
- Collaborate with AppSec for deeper assessments

# Reliability and Observability

- Use logs, metrics, traces to investigate failures
- Design tests to expose operational risk
- Collaborate with SRE/DevOps on incident learnings
