Agentic System Record-and-Replay Testing Technique

An Agentic System Record-and-Replay Testing Technique is a testing technique that captures agent execution trajectorys for deterministic replay in regression testing scenarios.

• AKA: Agent Trajectory Recording Technique, Deterministic Replay Testing, Agent Session Replay Method, Execution Trace Replay Technique.
• Context:
  • It can typically record agent decision sequences with environmental states and action outcomes for exact reproduction.
  • It can typically preserve non-deterministic elements like random seeds, timestamps, and external API responses.
  • It can typically enable debugging efficiency through step-by-step replay with state inspection capability.
  • It can often support differential testing by replaying identical scenarios across system versions.
  • It can often facilitate test case generation from production traces with anonymization processes.
  • It can often integrate with continuous integration systems for automated regression validation.
  • It can range from being a Shallow Recording to being a Deep Recording, depending on its state capture depth.
  • It can range from being a Synchronous Replay to being an Accelerated Replay, depending on its execution speed.
  • It can range from being a Exact Replay to being a Fuzzy Replay, depending on its tolerance level.
  • It can range from being a Single-Session Replay to being a Multi-Session Replay, depending on its scope coverage.
  • ...
• Examples:
  • LLM Agent Recording Techniques, such as:
    • Conversation History Recording capturing prompt-response pairs with context states.
    • Tool Call Recording preserving function invocations and return values.
  • Multi-Agent Recording Techniques, such as:
    • Agent Interaction Recording tracking message exchanges and coordination events.
    • Emergent Behavior Recording capturing collective decision patterns.
  • RAG System Recording Techniques, such as:
    • Retrieval Trace Recording storing querys, retrieved documents, and ranking scores.
  • ...
• Counter-Examples:
  • Live Testing Technique, which executes in real-time without replay capability.
  • Synthetic Test Generation, which creates artificial scenarios rather than recording actual executions.
  • Snapshot Testing, which captures state at single points rather than full trajectorys.
