Agile software development is widely adopted due to its emphasis on rapid delivery, continuous feedback, and customer collaboration. However, maintaining software quality within short iteration cycles remains a significant challenge. Conventional scripted testing methods are often insufficient for identifying hidden defects, usability concerns, and unexpected system behaviors. Exploratory testing offers a dynamic approach in which learning, test design, and execution occur simultaneously. This study explores the integration of advanced exploratory testing practices, including session-based testing, risk-driven prioritization, defect analytics, AI-supported scenario generation, and collaborative testing. It evaluates their role in strengthening Agile quality assurance, discusses implementation strategies, and highlights associated challenges and benefits.
