This report provides a detailed analysis of the VisualSign Parser codebase: Coverage Analysis (per-package with lcov): - visualsign-core: 84.65% (40 tests) ✅ EXCELLENT - visualsign-ethereum: 41.19% (36 tests) - ERC20/Uniswap: 98%+, core needs work - visualsign-solana: 73.16% (29 tests) - Jupiter: 91.3%, but Stakepool: 11.6% - visualsign-sui: 20 tests (coverage tool issue to investigate) - visualsign-tron: 0% (0 tests) - CRITICAL GAP - visualsign-unspecified: 0% (0 tests) - CRITICAL GAP - parser-app: 3.28% (1 test) - CRITICAL GAP Idiomatic Rust Analysis: - Overall code quality is GOOD - Excellent error handling, type safety, and modern patterns - Strong lint configuration (#![deny(clippy::unwrap_used)]) - Minor improvements suggested for iterator usage and error enums Priority Recommendations: 1. CRITICAL: Add integration tests for parser-app (currently 3.28%) 2. CRITICAL: Test Solana stakepool preset (currently 11.6%) 3. HIGH: Improve Ethereum core coverage (currently 41.19%) 4. HIGH: Investigate Sui coverage tool compatibility 5. HIGH: Add tests for TRON parser (0%) or document as unsupported The report includes a detailed implementation roadmap, testing strategy, and specific file locations for all identified issues.
This PR adds a sophisticated CI workflow for tracking test coverage with: Features: - Per-package coverage analysis using cargo-llvm-cov - Dependency-aware testing (auto-tests packages that depend on changes) - Coverage diff reports comparing PR vs base branch - Automated PR comments with detailed coverage breakdown - Threshold enforcement with configurable limits - Module-level coverage breakdown in reports Workflow Components: 1. detect-changes: Identifies changed packages and their dependents 2. coverage: Runs tests and generates lcov reports (matrix strategy) 3. coverage-report: Compares with base and posts PR comment 4. coverage-status: Enforces thresholds and fails if needed Scripts: - detect-changed-packages.sh: Finds affected packages using git diff - parse-coverage.sh: Extracts statistics from lcov files - generate-coverage-diff.sh: Creates markdown reports with diffs - check-coverage-thresholds.sh: Validates against configured limits - get-base-coverage.sh: Downloads base branch coverage for comparison Configuration: - .github/coverage-config.yml: Per-package thresholds and policies - Configurable critical/warning/good thresholds - Max coverage drop limits (e.g., fail if drops > 5%) - Package groups for organized reporting Example PR Comment Output: ``` 📦 Package Coverage | Package | Coverage | Change | Status | |---------------------|----------|-------------|--------------| | visualsign | 84.65% | ➡️ 0.00% | ✅ Excellent | | visualsign-solana | 75.23% | 📈 +2.07% | 🟢 Good | | parser_app | 45.50% | 📉 -3.22% | 🔴 Critical | ``` Benefits: - Immediate visibility into coverage impact of changes - Prevents accidental coverage drops - Encourages test-driven development - Tracks coverage trends over time - Identifies packages needing more tests Documentation: - .github/COVERAGE.md: Complete guide for developers - Includes troubleshooting, best practices, and examples - Documents threshold levels and policies Related to: IDIOMATIC_RUST_AND_COVERAGE_REPORT.md analysis
