…oints Add 16 new tests to api_integration.rs covering stats, chunk_proof, mmr_peaks, mmr_subtree, fetch_nodes, checkpoint coordination, replica sync status, and delete happy path. Create fs_integration.rs with 14 tests covering all 6 FS endpoints (put/get/delete file, mkdir, ls, index_root) including edge cases like invalid paths, overwrites, large multi-chunk files, and directory-as-file errors.
The CI coverage job used `cargo llvm-cov --lib` which only runs unit tests inside src/. This missed all 56 integration tests in tests/*.rs, reporting 30% instead of the actual ~42%. Change to `--tests` so integration tests are included in the coverage measurement.
…HTTP tests only Add auth_integration and disk_integration test suites that exercise the HTTP API with mocked chain dependencies (MockResolver) and the DiskStorage (RocksDB) backend respectively. Update CI coverage to measure only integration tests (--test flags) instead of --tests, so coverage reflects code reachable through the public API.
…ators for testability Extract chain interactions from AgreementCoordinator, ChallengeResponder, CheckpointCoordinator, and ReplicaSyncCoordinator behind per-coordinator traits (AgreementChainClient, ChallengeChainClient, CheckpointChainClient, ReplicaSyncChainClient), following the existing MembershipResolver pattern. Each coordinator now takes a `Box<dyn XChainClient>` instead of hardcoding `Option<OnlineClient<PolkadotConfig>>`, enabling mock-based unit testing without a live chain. Adds 30 new unit tests across all four coordinators.
The base branch may not have all integration test files that exist on the PR branch. Dynamically check which test files exist before passing --test flags to cargo llvm-cov. Also treat empty coverage values as 0 to prevent awk syntax errors in the comparison step.
… for CI coverage Move 29 coordinator mock tests from #[cfg(test)] blocks in source files to integration test files under provider-node/tests/. CI measures provider-node coverage from integration tests only, so these tests were invisible to the coverage gate despite exercising production code paths. - Create 4 integration test files (agreement, challenge, checkpoint, replica) - Remove #[cfg(test)] blocks from the 4 coordinator source files - Make tested methods pub so integration tests can call them - Use newtype SharedMock wrappers to satisfy orphan rules - Add new test targets to CI coverage discovery loop in check.yml
…coverage exclusion Move production Subxt chain client implementations into dedicated *_subxt.rs files so they can be excluded from CI coverage metrics alongside command.rs, cli.rs, and main.rs. This shrinks the coverage denominator to only testable code, giving a more accurate picture of actual test coverage.
…ifying CI matrix - Remove runtime-matrix job — both test jobs now use single runtime (web3-storage-paseo) - integration-tests → "Zombienet Smoke Test": keeps relay-chain topology, runs demo + fs-demo-ci + s3-demo-ci, drops redundant disk provider - sc-integration-tests → dev-mode chain (2s blocks, instant finality) to fix sc-token-gated timeout flakiness - Layer 0 comprehensive coverage remains in e2e-integration-tests (dev-mode, ~100 test cases)
…ases, and storage utilities Cover previously untested code paths to increase provider-node coverage: - storage_integration.rs: 23 tests for hex encode/decode, merkle tree building, chunk collection, and tree size calculation - api_integration.rs: 11 tests for invalid hex, missing nodes, invalid base64, and signing-unavailable error paths - fs_integration.rs: 4 tests for empty body, mkdir validation, delete-then-list, and nested directories - s3_integration.rs: 5 tests for HEAD/DELETE nonexistent, empty body, metadata roundtrip, and empty bucket listing - replica_sync_coordinator_integration.rs: 7 tests for get_active_replica_duties filter paths and handle commands
…, events, and runtime API Cover previously untested pallet logic: challenge response cost splits across 5 time brackets, multi-challenge slashing, provider checkpoint leader election with real Sr25519 signatures, grace period fallback, reward pool distribution, replica sync flow with error paths, event assertions for 6 core extrinsics, and 12 runtime API query tests.
…ponder Add 8 success-path tests to pallet-drive-registry exercising the previously untested _internal functions (create_bucket_internal, request_primary_agreement_internal, cleanup_bucket_internal, set_member_internal, remove_member_internal) via a setup_provider() helper that follows the S3 pallet pattern. Add 7 challenge responder integration tests with realistic storage data setup (init bucket, store chunk, build Merkle tree, commit to MMR) covering the full respond_to_challenge() path: successful proof generation and submission, missing bucket, bad chunk index, submission failure, callback invocation, and pause/resume behavior. Update CI coverage to measure all 3 pallets together instead of only pallet-storage-provider, with benchmarking file exclusions.
…r node The Zombienet smoke test fails with stale nonce (1010) on the S3 demo because both the demo client and the provider node's background coordinators (agreement, checkpoint) submit transactions as //Alice. Switch S3 CI test to //Bob to eliminate the race condition. Also remove storage_integration.rs — its utility function tests are redundant since all functions are already exercised through the endpoint integration tests.

…ops, glob CI test list - checkpoint.rs: replace if/else fallback with direct assert_ok! for deterministic test - challenge_responder/checkpoint_coordinator: replace 300ms fixed sleeps with tokio::time::timeout poll loops (5s timeout, 10ms poll) for CI robustness - check.yml: replace hardcoded integration test list with glob-based discovery
…CI coverage HIGH: - command.rs: replace expect() with error return in sync_multiaddr_on_chain - agreement_coordinator_subxt.rs: replace expect() with defensive continue on key parsing - mock.rs: add warning comment about run_to_block not calling pallet hooks MEDIUM: - check.yml: add TEST_FLAGS guard on PR side, validate coverage values are non-empty - replica_sync mock: remove dead block_on methods (panic footgun in async context) - misc.rs: fix remove_slashed_works to slash reserved balance (matches production) - lib.rs: restrict _subxt modules to pub(crate) visibility
