Application testing is a systematic security process within cybersecurity that evaluates software applications to identify vulnerabilities, weaknesses, and potential exploits. This critical examination encompasses various methodologies applied throughout the software development lifecycle, including source code analysis, behavioral observation under different conditions, and simulated adversarial attacks to uncover exploitable pathways and insecure configurations.

The primary goal of application testing is to strengthen an application's defensive capabilities against evolving cyber threats, preventing unauthorized access, data breaches, and service disruptions. By integrating comprehensive testing as an essential security practice, organizations proactively manage cyber risks, enhance resilience against sophisticated attacks, and protect critical digital assets while maintaining regulatory compliance.
