# Expanded Reachability Benchmark Fixtures

## Module
__Tests

## Status
IMPLEMENTED

## Description
Expanded benchmark corpus with real CVE cases (WordPress, Rust/Axum, runc, Redis) and cross-platform test runners.

## Implementation Details
- **Reachability Test Corpus**: `src/__Tests/reachability/` -- multi-language reachability test corpus with labeled samples for PHP (WordPress), Rust (Axum), Go (runc), C (Redis), and other ecosystems.
- **Benchmark Datasets**: `src/__Tests/__Datasets/` -- ground-truth datasets for reachability benchmarks with labeled reachable/unreachable code paths.
- **Scanner Analyzers Benchmark**: `src/Bench/StellaOps.Bench/Scanner.Analyzers/StellaOps.Bench.ScannerAnalyzers/` -- benchmark runner that executes scanner analyzers against the reachability corpus and measures precision/recall.
- **Baseline Loader**: `src/Bench/StellaOps.Bench/Scanner.Analyzers/StellaOps.Bench.ScannerAnalyzers/Baseline/BaselineLoader.cs` -- loads ground-truth baseline data for benchmark comparison.

## E2E Test Plan
- [ ] Run the reachability benchmark against the WordPress (PHP) corpus and verify precision and recall metrics are computed against the ground truth labels
- [ ] Run the benchmark against the Rust/Axum corpus and verify cross-language reachability analysis produces correct results
- [ ] Run the benchmark against the runc (Go) corpus and verify native code reachability paths are correctly identified
- [ ] Run the benchmark against the Redis (C) corpus and verify native memory access patterns are correctly analyzed
- [ ] Verify cross-platform compatibility: run the benchmark on both Linux and Windows and confirm results are identical
- [ ] Verify new fixture addition: add a new labeled sample to the corpus and confirm the benchmark runner includes it in the next evaluation
