Testing & Architecture

Zene prioritizes reliability and maintainability. This section covers the testing infrastructure and architectural verification patterns.

Mocking System

To test agent logic without incurring LLM costs or network latency, we implemented a robust mocking system:

• MockAgentClient: Simulates LLM responses. It can be pre-loaded with a sequence of ChatResponse objects to test specific conversation flows (e.g., Tool Calls -> Output -> Reflection).
• MockUserInterface: Intercepts UI calls (like confirmation prompts) to allow headless testing of interactive features.

Test Levels

Unit Tests

Covered individual components like Executor and Orchestrator.

• Location: src/agent/executor.rs, src/agent/orchestrator.rs
• Scope: fast, isolated logic verification.

Integration Tests

Verifies the complete agent loop.

• Location: tests/it_agent_flow.rs
• Scope: Simulates a full "Plan -> Execute -> Reflect" cycle using mocks.

Running Tests

Developers can run the full suite using standard Cargo commands:

cargo test

To run specifically the integration tests:

cargo test --test it_agent_flow
