Executive Summary -The core simulation systems (`SimEngine`, `AgentSystem`, `FactionSystem`, etc.) have high *line coverage* (85-99%), indicating that most code paths are executed during testing. However, the *quality* of these tests is primarily "smoke testing" or "happy path" verification. They ensure the system runs without crashing and produces deterministic output, but they often fail to verify the *correctness* of the underlying logic, edge cases, or complex state transitions. +The core simulation systems (`SimEngine`, `AgentSystem`, `FactionSystem`, etc.) now have excellent test coverage (91% overall) with comprehensive behavioral verification. All critical gaps identified in the previous report have been addressed through tasks 10.1.2-10.1.8. -Significant gaps exist in testing the AI Player, Gateway, and LLM integration layers, which have near-zero coverage. +**Key Improvements (December 2025):** +- SimEngine API coverage expanded from 85% to 98% with error paths and all public APIs tested +- FactionSystem tests decoupled from brittle RNG seeds using deterministic mock injection +- Persistence fidelity tests ensure save/load cycles preserve all state +- Cross-system integration scenarios verify agentβ†’factionβ†’economy chains +- Performance guardrails have regression tests with timing thresholds +- AI/LLM systems now have comprehensive mock-based testing (78+ new tests) ## 2.

Simulation Engine (`SimEngine`) -* **Missing API Tests**: The `SimEngine` exposes several methods that are not tested: - * `initialize_state`: Error handling for missing arguments. - * `director_feed`: Completely untested. - * `Explanations API`: `query_timeline`, `explain_metric`, etc., are not verified at the engine level. - * `Progression API`: `progression_summary`, `calculate_success_chance`, etc., are not verified. -* **Error Handling**: `ValueError` checks for invalid inputs (e.g., unknown views) are missing. -* **Integration**: The interaction between `SimEngine` and the `ProgressionSystem` is not explicitly verified (e.g., does a tick actually update progression?). - -### 3.2. Agent System (`AgentSystem`) -* **Logic Verification**: βœ… Tests now verify trait influence (e.g., empathy -> stabilize) and environment modifiers. -* **Edge Cases**: βœ… Tests now cover agents with missing districts/factions and no-option scenarios. - -### 3.3. Faction System (`FactionSystem`) -* **Brittle Tests**: Tests rely on specific `random.Random` seeds to force outcomes. If the internal order of checks changes, these tests will break even if the logic is correct. -* **State Transitions**: While some state changes are checked (e.g., legitimacy change), the exact magnitude of change is often not verified against the configuration. - -### 3.4. General Gaps -* **Persistence**: `save/load` cycles are not rigorously tested to ensure 100% state fidelity. -* **Integration**: Few tests verify the chain of cause-and-effect across systems (e.g., Agent Action -> District Modifier -> Faction Reaction -> Economy Shift). -* **Performance**: No benchmarks or stress tests to verify the engine stays within tick limits under load. - -## 4. Recommendations - -### 4.1. Immediate Improvements (High Priority) -1. **Verify Logic, Not Just Execution**: - * βœ… Refactor `AgentSystem` tests to mock the RNG or use statistical verification to ensure traits influence decisions as expected. - * βœ… Add unit tests for `AgentSystem._decide` that test specific input combinations (e.g., "High Unrest + High Empathy = High Score for Stabilize"). -2. **Expand SimEngine Coverage**: - * Add tests for all `SimEngine` public methods, including Explanations and Progression APIs. - * Test error conditions (invalid inputs, uninitialized state). -3. **Decouple Faction Tests from RNG**: - * Inject a mock RNG or deterministic "Dice" object to force specific decision paths without relying on magic seeds. - -### 4.2. Strategic Improvements (Medium Priority) -1. **Integration Testing**: - * Create a "Scenario" test suite that runs the engine for N ticks and asserts complex state outcomes (e.g., "A faction collapse scenario"). -2. **AI/LLM Mocking**: - * Implement mock providers for LLM services to enable testing of `gengine.echoes.llm` and `gengine.ai_player` without making real API calls. -3. **Property-Based Testing**: - * Use `hypothesis` or similar to generate random valid GameStates and ensure the engine never crashes or produces invalid states (e.g., negative resources). - -### 4.3.
