Alignment with ADR-017: ✅ Perfect alignment with three-tier strategy.

1.2 SBT Command Aliases¶

Status: ✅ COMPLETE

Location: build.sbt

Tier 1: testEssential¶

addCommandAlias(
  "testEssential",
  """; compile-all
    |; testOnly -- -l SlowTest -l IntegrationTest
    |; rlp / test
    |; bytes / test
    |; crypto / test
    |""".stripMargin
)

Status: ✅ Implemented as specified in ADR-017

Tier 2: testStandard¶

addCommandAlias(
  "testStandard",
  """; compile-all
    |; testOnly -- -l BenchmarkTest -l EthereumTest
    |""".stripMargin
)

Status: ✅ Implemented as specified in ADR-017

Tier 3: testComprehensive¶

addCommandAlias(
  "testComprehensive",
  "testAll"
)

Module-Specific Commands¶

✅ testCrypto, testVM, testNetwork, testDatabase
✅ testRLP, testMPT, testState, testConsensus

Alignment with ADR-017: ✅ Complete implementation of three-tier test strategy.

1.3 GitHub Actions CI/CD Integration¶

Status: ✅ COMPLETE with ethereum/tests integration

Pull Request Workflow (`.github/workflows/ci.yml`)¶

Current Implementation:

- name: Run tests with coverage
  run: sbt testCoverage

- name: Validate KPI Baselines
  run: sbt "testOnly *KPIBaselinesSpec"

- name: Run Ethereum/Tests Integration Tests
  run: sbt "IntegrationTest / testOnly *SimpleEthereumTest *BlockchainTestsSpec"
  timeout-minutes: 10

Status: ✅ Using testCoverage and ethereum/tests integration

Gap Analysis vs ADR-017: - ⚠️ Current CI uses testCoverage instead of tiered testEssential + testStandard - ✅ Includes ethereum/tests integration (SimpleEthereumTest, BlockchainTestsSpec) - ✅ Includes KPI validation - ✅ Has appropriate timeout (10 minutes for ethereum/tests)

Recommendation: CI workflow could be updated to explicitly use testEssential and testStandard commands for clarity, but current implementation is functionally equivalent.

Nightly Build Workflow (`.github/workflows/nightly.yml`)¶

Current Implementation: - Builds Docker images only - No test execution

Gap: Does not run comprehensive tests as specified in ADR-017

Recommendation: Nightly workflow should run testComprehensive to validate full ethereum/tests suite.

Ethereum/Tests Nightly Workflow (`.github/workflows/ethereum-tests-nightly.yml`)¶

Current Implementation: ✅ EXCELLENT

jobs:
  comprehensive-ethereum-tests:
    timeout-minutes: 60
    steps:
      - name: Validate KPI Baselines
        run: sbt "testOnly *KPIBaselinesSpec"

      - name: Run Comprehensive Ethereum/Tests Suite
        run: sbt "IntegrationTest / testOnly com.chipprbots.ethereum.ethtest.*"

Status: ✅ Dedicated ethereum/tests nightly validation - ✅ KPI baseline validation - ✅ Comprehensive ethereum/tests suite - ✅ Proper timeout (60 minutes) - ✅ Artifact upload for test results - ✅ Summary report generation

Alignment with ADR-017: ✅ Excellent - implements nightly comprehensive testing exactly as specified.
