… 69.9% Adds offline (no live node) JUnit4 unit tests that drive the generated precompiled and auth contract wrappers, their high-level Service classes, and several pure-Java codec/model/util classes. The wrappers are exercised via a mocked Client (Mockito) plus ABI round-trips (encode known args with the SDK's own FunctionEncoder, feed to the getXxxInput/getXxxOutput decoders) and stubbed client.call(...) outputs, so no chain or JNI transaction signing is required. Unit-only JaCoCo (verifiable in CI/Codecov, which ignores integration-test dirs): instruction 54.57% -> 69.87%, line 56.24% -> 68.22%, branch -> 67.79%, method -> 76.07%. Notable package gains: contract/auth/contracts 6.7% -> 88.2%, precompiled/crud 6.8% -> 67%, consensus 12.5% -> 66%, balance 20% -> 72%, bfs 36% -> 74%, transaction/tools 36% -> 89%. Test-only change; no production code modified.

What
Adds offline (no live node) JUnit4 unit tests that substantially raise the unit-test coverage tracked by Codecov.
Unit-only JaCoCo (the CI/Codecov-visible metric —
.codecov.ymlignores the integration-test dirs):26 new test files, all passing offline under Java 8. No production code is modified.
How
The biggest "uncovered" chunks were the generated precompiled and auth contract wrappers and their high-level
*Serviceclasses — which looked integration-only but are actually pure-Java once instantiated. The tests:Client(Mockito) + a realnew CryptoSuite(CryptoType.ECDSA_TYPE)keypair — noBcosSDK.build/Client.build/ network;getXxxInput/getXxxOutputdecoders via ABI round-trips (encode known args with the SDK's ownFunctionEncoder, set them on aTransactionReceipt, decode, assert);client.call(...)with ABI-encoded outputs;ContractLoader,ContractCodec,AbiTypes,ABIDefinition,TransactionReceipt,JsonTransactionResponse,StringUtils,CryptoSuite, …) directly.Notable package gains

The remaining gap is genuinely node/JNI-dependent and not unit-testable:
ClientImplJSON-RPC, live transaction submission (nativeTransactionBuilderJniObjsigning), and theeventsub/filterpush loops. Those are exercised by theintegrationTestsuite instead.🤖 Generated with Claude Code
