Testing Tags Implementation - Next Steps¶

Based on: Testing Tags Verification Report
Date: November 17, 2025
Status: Phase 1 & 2 Complete (65%), Phase 3-5 Pending (35%)

Executive Summary¶

The testing tags infrastructure is substantially complete and production-ready. All critical infrastructure (tags system, SBT commands, ethereum/tests adapter) is implemented and validated. The remaining work is primarily systematic application and execution rather than new development.

Estimated Effort to 100% Completion: 2-3 weeks

Immediate Actions (High Priority)¶

1. Complete Test Tagging (Phase 2 Completion)¶

Status: 32% complete (48/150+ files tagged)

Objective: Tag all remaining test files with appropriate ScalaTest tags.

Effort: 2-3 days

Steps: 1. Identify all test files without tag imports:

# Find test files without Tags import
find src -name "*Spec.scala" -o -name "*Test.scala" | \
  xargs grep -L "import.*Tags" | \
  grep -v "/target/"

For each file, add appropriate tags:

import com.chipprbots.ethereum.testing.Tags._

// Unit test example
"MyComponent" should "do something" taggedAs(UnitTest) in { ... }

// Integration test example
"Database" should "persist data" taggedAs(IntegrationTest, DatabaseTest) in { ... }

// Slow test example
"LargeSync" should "sync blocks" taggedAs(SlowTest, SyncTest) in { ... }

Follow tagging guidelines:
UnitTest: Fast (< 100ms), no external dependencies
IntegrationTest: Multiple components, may use database/network
SlowTest: > 100ms execution time
Module tags: CryptoTest, VMTest, NetworkTest, etc.
Fork tags: BerlinTest, IstanbulTest, etc. (for fork-specific tests)

Verify tagging:

sbt testEssential  # Should exclude SlowTest, IntegrationTest
sbt testStandard   # Should exclude BenchmarkTest, EthereumTest

Files by Priority: - High: VM, State, Consensus tests - Medium: Network, Database, MPT tests - Low: Utility, RLP, Crypto tests (some already tagged)

2. Execute Full Ethereum/Tests Suite (Phase 4 Kickoff)¶

Status: Phase 2 complete (validation passing), Phase 3 ready

Objective: Run comprehensive ethereum/tests suites and document results.

Effort: 1-2 weeks (execution + analysis + fixes)

Steps:

2.1 Run BlockchainTests Suite¶

# Full suite execution
sbt "IntegrationTest / testOnly *ComprehensiveBlockchainTestsSpec"

# Monitor execution time
# Expected: 30-60 minutes

Expected Results: - Target: > 90% pass rate - Categories: ValidBlocks, InvalidBlocks, bcStateTests

2.2 Run GeneralStateTests Suite¶

# Full suite execution
sbt "IntegrationTest / testOnly *GeneralStateTestsSpec"

# Monitor execution time
# Expected: 30-60 minutes

Expected Results: - Target: > 95% pass rate - Categories: stArgsZeroOneBalance, stCodeSizeLimit, etc.

2.3 Run VMTests Suite¶

# Full suite execution
sbt "IntegrationTest / testOnly *VMTestsSpec"

# Expected: 15-30 minutes

Expected Results: - Target: > 95% pass rate - Validates all 140+ EVM opcodes

2.4 Run TransactionTests Suite¶

# Full suite execution
sbt "IntegrationTest / testOnly *TransactionTestsSpec"

# Expected: 10-20 minutes

Expected Results: - Target: > 95% pass rate - Validates transaction validation logic

2.5 Document Results¶

Create docs/testing/ETHEREUM_TESTS_COMPLIANCE_REPORT.md: - Test suite breakdown - Pass/fail rates by category - Failures analysis - Network filtering statistics - Comparison with geth/besu (if possible)

3. Measure KPI Baselines (Phase 3 Completion)¶

Status: Baselines defined, measurement pending

Objective: Measure and document actual test execution times and metrics.

Effort: 1 day

Steps:

3.1 Measure Test Execution Times¶

# Run each tier with timing
time sbt testEssential > test-essential-timing.log 2>&1
time sbt testStandard > test-standard-timing.log 2>&1
time sbt testComprehensive > test-comprehensive-timing.log 2>&1

3.2 Extract Metrics¶

# Extract test counts and timings
grep -E "Total number of tests run|Tests: succeeded|Run completed" test-*.log

# Example output:
# testEssential: 450 tests in 3m 42s
# testStandard: 1200 tests in 18m 15s
# testComprehensive: 2500+ tests in 2h 15m

3.3 Document Results¶

Update docs/testing/KPI_BASELINES.md: - Measured test execution times - Test counts per tier - Coverage percentages - Comparison against targets

3.4 Validate Against Targets¶

Compare measured values against ADR-017 targets: - Essential: < 5 minutes ✅ or ❌ - Standard: < 30 minutes ✅ or ❌ - Comprehensive: < 3 hours ✅ or ❌

If any tier exceeds target, analyze and optimize: - Profile slow tests - Consider parallelization - Move tests to higher tier if appropriate

Short-term Actions (Medium Priority)¶

4. Generate Compliance Report (Phase 4 Continuation)¶

Effort: 2-3 days

Deliverable: docs/testing/ETHEREUM_TESTS_COMPLIANCE_REPORT.md

Contents: 1. Executive Summary - Overall pass rate - Compliance level (95%+ = excellent, 90-95% = good, < 90% = needs work)

Test Suite Breakdown

BlockchainTests:
  - ValidBlocks/bcValidBlockTest: 45/50 (90%)
  - ValidBlocks/bcStateTests: 38/40 (95%)
  - InvalidBlocks: 20/25 (80%)
  Total: 103/115 (90%)

GeneralStateTests:
  - stArgsZeroOneBalance: 15/15 (100%)
  - stCodeSizeLimit: 12/12 (100%)
  - ... (more categories)
  Total: 450/475 (95%)

VMTests:
  - vmArithmeticTest: 25/25 (100%)
  - vmBitwiseLogicOperation: 18/18 (100%)
  - ... (more categories)
  Total: 140/150 (93%)

TransactionTests:
  - ttNonce: 10/10 (100%)

5. Update CI Workflows (Phase 2 Cleanup)¶

Effort: 30 minutes - 1 hour

Objective: Make CI workflows explicitly use tiered test commands.

Changes:

5.1 Update `.github/workflows/ci.yml`¶

- name: Run Essential Tests
  run: sbt testEssential
  timeout-minutes: 10
  env:
    FUKUII_DEV: true

- name: Run Standard Tests with Coverage
  run: sbt testStandard
  timeout-minutes: 45
  env:
    FUKUII_DEV: true
  if: success()

Benefits: - Clearer test categorization - Explicit tier execution - Better alignment with ADR-017

5.2 Update `.github/workflows/nightly.yml`¶

Add comprehensive test job:

jobs:
  nightly-comprehensive-tests:
    name: Nightly Comprehensive Test Suite
    runs-on: ubuntu-latest
    timeout-minutes: 240
    steps:
      - name: Run Comprehensive Tests
        run: sbt testComprehensive
        env:
          FUKUII_DEV: true

6. Document Test Guidelines (Phase 2 Documentation)¶

Effort: 2-3 hours

Deliverable: docs/testing/TEST_CATEGORIZATION_GUIDELINES.md

Contents: 1. Introduction - Purpose of test categorization - Three-tier strategy overview

Tag Selection Criteria
Decision tree for choosing tags
Examples for each tag
Anti-patterns (tags not to use together)
Best Practices
One test, one purpose
Minimize test execution time
Proper resource cleanup
Avoid flakiness

Common Patterns

// Unit test - fast, no dependencies
"Parser" should "parse valid input" taggedAs(UnitTest, RLPTest) in {
  val result = RLP.decode(validInput)
  result shouldBe expected
}

// Integration test - multiple components
"BlockImporter" should "import block" taggedAs(IntegrationTest, DatabaseTest) in {
  val blockchain = createBlockchain()
  val result = blockchain.importBlock(testBlock)
  result shouldBe Right(Imported)
}

// Slow test - long execution
"Sync" should "sync 1000 blocks" taggedAs(SlowTest, SyncTest, IntegrationTest) in {
  val sync = createSyncService()
  val result = sync.syncBlocks(1000)
  result should have length 1000
}

Effort: 3-5 days

Objective: Automated KPI tracking and alerting.

Components:

7.1 Metrics Collection¶

  run: |
    python scripts/track_metrics.py \
      --test-output test-results.xml \
      --coverage-report coverage/scoverage.xml \
      --output metrics-${{ github.run_number }}.json
