Quick Start for Developers

Before Your Next Push

# 1. Test locally
./scripts/test-config-matrix.sh

# 2. If you see green checkmarks, you're good
# 3. Commit and push
git commit -m "feature: your change"
git push

Testing Specific Configuration

./scripts/test-config-matrix.sh --config minimal
./scripts/test-config-matrix.sh --config full-ai --verbose

Validate Flag Combination

./scripts/validate-cmake-config.sh \
  -DYAZE_ENABLE_GRPC=ON \
  -DYAZE_ENABLE_REMOTE_AUTOMATION=OFF  # This will warn!

Testing Coverage

Tier 1 (Every Commit - Standard CI)

✓ ci-linux      (gRPC + Agent CLI)
✓ ci-macos      (gRPC + Agent UI + Agent CLI)
✓ ci-windows    (gRPC core features)

Tier 2 (Nightly - Feature Combinations)

Linux (6 configurations):

✓ minimal       - No AI, no gRPC (core functionality)
✓ grpc-only     - gRPC without automation
✓ full-ai       - All features enabled
✓ cli-no-grpc   - CLI only, no networking
✓ http-api      - REST endpoints
✓ no-json       - Ollama mode (no JSON parsing)

macOS (4 configurations):

✓ minimal       - GUI, no AI
✓ full-ai       - All features
✓ agent-ui      - Agent UI panels
✓ universal     - ARM64 + x86_64 binary

Windows (4 configurations):

✓ minimal       - No AI
✓ full-ai       - All features
✓ grpc-remote   - gRPC + remote automation
✓ z3ed-cli      - CLI executable

Total: 14 nightly configurations across 3 platforms

Tier 3 (As Needed - Architecture-Specific)

• Windows ARM64 - Debug + Release
• macOS Universal - arm64 + x86_64
• Linux ARM - Cross-compile tests

Configuration Problems Fixed

1. GRPC Without Automation

  • Symptom: gRPC headers included but server never compiled
  • Status: FIXED - CMake auto-enforces constraint
  • Test: grpc-only config validates this

2. HTTP API Without CLI Stack

  • Symptom: REST endpoints defined but no dispatcher
  • Status: FIXED - CMake auto-enforces constraint
  • Test: http-api config validates this

3. Agent UI Without GUI

  • Symptom: ImGui panels in headless build
  • Status: FIXED - CMake auto-enforces constraint
  • Test: Local script tests this

4. AI Runtime Without JSON

  • Symptom: Gemini service can't parse responses
  • Status: DOCUMENTED - matrix tests edge case
  • Test: no-json config validates degradation

5. Windows GRPC ABI Mismatch

  • Symptom: Symbol errors with old gRPC on MSVC
  • Status: FIXED - preset pins stable version
  • Test: ci-windows validates version

6. macOS ARM64 Dependency Issues

  • Symptom: Silent failures on ARM64 architecture
  • Status: DOCUMENTED - mac-uni tests both
  • Test: universal config validates both architectures

Integration Checklist

CMake Integration

  • No changes needed to existing presets
  • Constraint enforcement already exists in cmake/options.cmake
  • All configurations inherit from standard base presets
  • Backward compatible with existing workflows

CI/CD Integration

  • New workflow created: .github/workflows/matrix-test.yml
  • Existing workflows unaffected
  • Matrix tests complement (don't replace) standard CI
  • Results aggregation and reporting
  • Failure logging and debugging support

Developer Integration

  • Local test script ready to use
  • Platform auto-detection implemented
  • Easy integration into pre-push workflow
  • Clear documentation and examples
  • Help text and usage instructions

Next Steps for Users

Immediate (Today)

  1. Read the quick start:

    cat docs/internal/testing/QUICKSTART.md

  2. Run local matrix tester:

    ./scripts/test-config-matrix.sh

  3. Add to your workflow (optional):

    # Before pushing:
./scripts/test-config-matrix.sh

Near Term (This Week)

  1. Use validate-config before experimenting:

    ./scripts/validate-cmake-config.sh -DYAZE_ENABLE_GRPC=ON ...

  2. Monitor nightly matrix tests:

    • GitHub Actions > Configuration Matrix Testing
    • Check for any failing configurations

Medium Term (This Month)

  1. Add matrix test to pre-commit hook (optional):

    # In .git/hooks/pre-commit
./scripts/test-config-matrix.sh --smoke || exit 1

  2. Review and update documentation as needed:

    • Add new configurations to /docs/internal/configuration-matrix.md
    • Update matrix test script when flags change

Long Term

  1. Monitor for new problematic patterns
  2. Consider Tier 3 testing when needed
  3. Evaluate performance improvements per configuration
  4. Plan future enhancements (see MATRIX_TESTING_IMPLEMENTATION.md)

Maintenance Responsibilities

Weekly

  • Check nightly matrix test results
  • Alert if any configuration fails
  • Review failure patterns

Monthly

  • Audit matrix configuration
  • Check if new flags need testing
  • Review binary size impact
  • Update documentation as needed

When Adding New CMake Flags

  1. Update cmake/options.cmake (define + constraints)
  2. Update /docs/internal/configuration-matrix.md (document + dependencies)
  3. Add test config to /scripts/test-config-matrix.sh
  4. Add matrix job to /.github/workflows/matrix-test.yml
  5. Update validation rules in /scripts/validate-cmake-config.sh
