We are witnessing the increased availability of powerful quantum computing facilities as a service; also, there are promising prospects of applying quantum computing in fields such as material-and drug discovery, as well as scheduling, and optimisation. With these prospects comes an inherent challenge of quality assurance of complex quantum programs. Quantum programs and programming frameworks are becoming more complex, and this complexity creates a gap, calling for novel and rigorous testing and debugging frameworks. In this talk, we present an overview of the fascinating emerging field of quantum software testing and its numerous challenges and opportunities. In particular, we review our recent research on characterising faults in hybrid quantum-classical architectures. This has led to a taxonomy of real faults in hybrid quantum-classical architectures. We also present our long-standing effort to establish a mature property-based testing framework for quantum programs both for fault-tolerant and for noisy architecture. We also present an automated debugging and runtime monitoring frameworks based on property-based testing.
