Performance and specialised testing
Check speed, load, security and accessibility.
📖 Key ideas
- Load testing: expected users; stress testing: beyond limits.
- Tools: JMeter, k6, Locust, Gatling.
- Measure response time, throughput, error rate.
- Accessibility testing checks WCAG compliance (axe, Lighthouse).
- Security testing is done with authorisation and specialist tools.
💡 Real-life example: Load testing is filling a bus to its seat count; stress testing is seeing what happens when you overfill it.
