Performance and security are non-negotiable aspects of software quality that often receive insufficient attention until something breaks in production. This category provides practical guidance on both disciplines – load testing, stress testing, API security validation, chaos engineering, and database performance analysis. These skills set senior QA engineers apart.
On the performance side, you will find tutorials covering the leading load testing tools including JMeter, Gatling, and Artillery, along with focused guides on API and database performance testing. The security articles address API vulnerability testing, penetration testing with Burp Suite, and building security awareness into your QA practice.
Chaos engineering rounds out the coverage, helping you proactively discover weaknesses before your users do. Each article balances tool-specific instruction with the broader thinking required to design meaningful performance and security tests. – Yuri Kan, Senior QA Lead
