Abstract :

Artificial intelligence (AI) is rapidly being integrated into application domains such as autonomous vehicles, health care, and cybersecurity; therefore, the requirements for dependable and robust AI-embedded systems are more pressing in these dynamic environments characterized by unpredictable variations in operational conditions. The traditional software testing methodologies that depend on static test cases and a predetermined set of scenarios usually fail to tackle the complexity of modern AI applications, resulting in undetected defects and security vulnerabilities. This study will evaluate adaptive test methods based on reinforcement learning (RL), fuzz testing, and other hybrid strategies for their application in software reliability assurance across environments such as stable, low-resource, high-load, and adversarial. The research is built upon a series of experiments on conversational chatbots, fraud detection systems, and autonomous navigation modules, demonstrating that RL-adaptive testing methods improve defect detection by 35-47% in dynamic environments compared to static testing methods and achieve 40-50% greater stability against stress (concerning the system itself). For the traditional testing methods, RL-based methods reduced failure rates by 75%; fuzz testing proved effective in detecting edge cases but was less stable when the same edge cases were instantiated in adversarial conditions.

Furthermore, the paper identifies prominent challenges in AI Software Testing, like environmental drifts and non-deterministic outputs, which are seen to be better adapted through RL-based methods. Although there is a trade-off regarding explainability and computational overhead, the data demonstrates that adaptive testing can transform safety-critical applications and highlights hybrid approaches combining the dynamic optimization of RL with the anomaly detection of fuzz testing. The description of the application areas presented in this document offers concrete recommendations to developers and engineers, enabling safer and more dependable AI in real systems.
