test(challenge-sdk): Add comprehensive test coverage #13
Conversation
…K modules Note: Remaining uncovered code in platform_client.rs and server.rs HTTP handlers requires integration testing with WebSocket connections and HTTP servers, which is beyond the scope of unit tests.
📝 WalkthroughWalkthroughAdds comprehensive unit tests across the challenge-sdk crate (data, database, errors, platform client, routes, server, submission/weight types, and a test challenge). No runtime logic or public API signatures were changed. Changes

363-380: Minor: Consider adding a persistence test to validate data durability across DB reopens.The current tests verify in-memory operations well, but a test that reopens the database after writes and verifies data persists would further validate the sled backend's durability guarantees. This is a nice-to-have enhancement for catching potential serialization or flush issues.
If you'd like, I can generate a persistence test that reopens the DB and verifies earlier writes are still present.

crates/challenge-sdk/src/weight_types.rs (1)
151-172: LGTM! Clean test coverage for WeightConfig.The tests appropriately validate the default configuration values and cloning behavior. The default value test is comprehensive, checking all six configuration fields.
crates/challenge-sdk/src/error.rs (1)
94-135: LGTM! Comprehensive error conversion tests.The test suite properly validates all
Fromtrait implementations for external error types and verifies Display formatting for error variants. Good use of pattern matching to verify error conversion correctness.crates/challenge-sdk/src/server.rs (4)
520-541: LGTM! Server configuration tests look solid.The tests properly validate both default configuration values and environment variable loading behavior.
543-658: LGTM! Comprehensive request/response type tests.The test suite thoroughly covers all request and response types, including success/error paths, builder methods (
with_time,with_cost), and default behaviors. Well-structured validation across EvaluationRequest, EvaluationResponse, ValidationRequest/Response, HealthResponse, and ConfigResponse.
660-727: LGTM! MockChallenge implementation is clean and effective.The mock implementation properly satisfies the ServerChallenge trait and includes appropriate test coverage for evaluate, validate, and config methods. The async tests correctly verify the mock behavior.
729-822: LGTM! Builder pattern tests are thorough.The test suite validates all builder methods and configurations, ensuring the fluent API works correctly. Good coverage of host/port configuration, custom configs, and environment-based setup.
crates/challenge-sdk/src/weights.rs (1)
116-215: LGTM! Excellent edge case coverage for weight utilities.The test suite thoroughly validates edge cases including zero/negative score totals, commitment generation properties (determinism, secret sensitivity, order-independence), and normalization behavior with zero-sum weights. Good use of floating-point tolerance in assertions.
crates/challenge-sdk/src/test_challenge.rs (3)
147-170: LGTM! Clean metadata accessor tests.The tests properly validate challenge ID, name, and version accessors, including the
with_idbuilder method.
172-250: LGTM! Comprehensive evaluation scenario coverage.The test suite thoroughly validates the evaluation logic across all bonus scenarios: zero bonus, maximum bonus, excessive bonus (clamping), and absent bonus. The score calculations and clamping behavior are properly verified.
252-261: LGTM! Validation edge case is covered.The test appropriately validates the null data scenario and verifies that errors are populated.
crates/challenge-sdk/src/database.rs (1)
297-494: Excellent test coverage for all database operations.The new tests comprehensively cover all public methods with proper isolation (tempdir), good edge-case handling (non-existent keys, deletion confirmation, timestamp-based deduplication), and consistent patterns. All assertions are correct—for example,
test_get_latest_resultsproperly validates that the HashMap groups by agent_hash and retains only the timestamp-maximum entry.
Add comprehensive test to validate data durability in ChallengeDatabase by verifying that all data types persist correctly across multiple database open/close cycles.

crates/challenge-sdk/src/database.rs (1)
319-332: LGTM! Solid coverage of agent and result retrieval operations.The tests correctly verify:
- Agent listing returns all saved agents
- All results can be retrieved across agents
- Latest results per agent are correctly identified based on timestamp
The
test_get_latest_resultsproperly handles the timestamp comparison by setting one result to 1 hour ago, ensuring deterministic test behavior.💡 Optional: Expand test_get_latest_results to cover multiple agents
Consider adding a scenario with multiple agents to more thoroughly verify the "latest per agent" behavior:
// Additional test case within test_get_latest_results: let result3 = EvaluationResult::new(uuid::Uuid::new_v4(), "agent2".to_string(), 0.80); db.save_result(&result3).unwrap(); let latest = db.get_latest_results().unwrap(); assert_eq!(latest.len(), 2); // One for agent1, one for agent2This would better demonstrate that the method maintains latest results independently for each agent.

297-304: LGTM! Clean test for challenge ID preservation.The test correctly verifies that the challenge ID is preserved and accessible via the
challenge_id()method.
393-425: LGTM! Comprehensive KV store operation tests.Excellent coverage of KV operations:
test_kv_deleteverifies both successful deletion and the behavior when deleting non-existent keystest_kv_keysensures all stored keys are properly listedThe tests correctly validate the expected behavior for both success and edge cases.
427-470: LGTM! Thorough metadata and version management tests.The tests properly validate:
- Metadata storage and retrieval with
set_meta/get_meta- Non-existent key handling returns
Noneas expected- Default version of 0 for new databases
- Version persistence after
set_versionAll test assertions align correctly with the implementation logic, including the default version fallback behavior.
472-565: Excellent comprehensive persistence testing! 🎉Outstanding test coverage of database persistence:
test_open_tree: Correctly validates custom tree creation and basic operationstest_flush: Ensures flush operations complete successfullytest_data_persistence_across_reopens: Exceptionally thorough test that validates all data types (agents, results, KV data, metadata, version) persist across multiple open/close/reopen cyclesThe persistence test uses proper scoping to ensure the database is dropped and closed between sessions, and includes an explicit
flush()to guarantee durability before closing. The third session provides excellent additional verification. This is best-practice testing for a persistence layer.
