Towards Reliable Task-Based Chatbots: Coverage, Mutation, and Repair
This research proposes a comprehensive framework for enhancing the reliability and maintainability of task-based chatbots, particularly those built with Dialogflow ES. It focuses on improving test coverage, designing novel mutation operators for fault detection, and developing automated repair strategies. The framework integrates systematic testing, mutation analysis, and continuous repair into regression pipelines, aiming to produce more robust and trustworthy conversational agents.

Improving intent and entity coverage is crucial for robust chatbots. This section details methods for automated and combinatorial test generation to maximize coverage while maintaining semantic correctness. Early experiments show promising results in identifying missing intents and entities.
Mutation testing evaluates test suite adequacy by introducing controlled faults. New mutation operators targeting intents, entities, and flow transitions are designed to reveal weaknesses and blind spots in chatbot behavior, enhancing fault detection capabilities beyond existing methods like MutaBot.
Failed test cases provide valuable insights for automated repair. This involves developing strategies to automatically suggest fixes for intents, training phrases, or dialogue flows. The goal is a continuous improvement loop, where repair suggestions are integrated and validated via regression testing.
