Major Gaps Remaining

Missing Test Files (13)

  1. SerializableTransactionTest.swift
  2. Bip32ECKeyPairTests.swift
  3. EpicChainURITests.swift
  4. NNSNameTests.swift
  5. EnumTypeTests.swift
  6. JsonRpc2_0RxTests.swift
  7. XEP6WalletTests.swift (separate from XEP6Wallet)
  8. MockEpicChainSwift.swift (test utility)
  9. MockBlocks.swift (test utility)
  10. JSON.swift (test utility)
  11. MockURLSession.swift (test utility)
  12. RIPEMD160Tests.swift

Critically Incomplete Test Files

  1. TransactionBuilderTests (47 missing tests)

    • Most transaction building scenarios not covered
    • Signing and witness management tests missing
    • Fee calculation tests missing

  2. SmartContractTests (23 missing tests)

    • Contract invocation tests missing
    • Function calling tests missing
    • Iterator handling tests missing

  3. NeoNameServiceTests (44 missing tests)

    • Domain registration tests missing
    • Record management tests missing
    • Resolution tests missing

  4. RequestTests (83 missing tests)

    • RPC request formation tests missing
    • Parameter validation tests missing

  5. ResponseTests (74 missing tests)

    • Response parsing tests missing
    • Error handling tests missing

Recommendations

Priority 1 - Critical Infrastructure

  1. Complete TransactionBuilder tests (foundation for all transactions)
  2. Complete Request/Response tests (RPC communication)
  3. Implement missing Bip32ECKeyPair tests (wallet generation)

Priority 2 - Contract Interaction

  1. Complete SmartContract tests
  2. Complete EpicChainToken tests
  3. Complete EpicPulseToken tests
  4. Complete PolicyContract tests

Priority 3 - Advanced Features

  1. Complete NeoNameService tests
  2. Implement EpicChainURI tests
  3. Complete remaining NFT tests

Priority 4 - Nice to Have

  1. Mock utilities for testing
  2. Additional edge case coverage
  3. Performance benchmarks

Test Coverage Metrics

By Module

  • Crypto: 80% coverage (missing Bip32, RIPEMD160)
  • Script: 95% coverage (comprehensive)
  • Transaction: 70% coverage (missing builder tests)
  • Contract: 40% coverage (many missing tests)
  • Wallet: 75% coverage (missing some XEP6 features)
  • Protocol: 20% coverage (request/response largely missing)
  • Types: 85% coverage (good coverage)
  • Utils: 90% coverage (well tested)

Notes

  1. Many C++ tests exist but don't match Swift test method names exactly
  2. Some Swift tests may not be applicable due to language differences
  3. Mock objects and test utilities need different approach in C++
  4. Some tests require RPC server mocking which needs implementation

Action Items

  1. ✅ Implement all placeholder tests (COMPLETE)
  2. ✅ Enhance ECKeyPair tests to match Swift (COMPLETE)
  3. ✅ Create comprehensive ScriptBuilder tests (COMPLETE)
  4. ⏳ Implement TransactionBuilder tests (PENDING)
  5. ⏳ Implement SmartContract interaction tests (PENDING)
  6. ⏳ Implement Request/Response tests (PENDING)
  7. ⏳ Create test utilities and mocks (PENDING)
