+# Quick Start - Testing NPM Packages
+
+## TL;DR
+
+```bash
+# From npm directory
+npm test                  # Run all unit and integration tests
+npm run test:perf        # Run performance benchmarks
+```
+
+## Current Status
+
+✅ **Test Suite:** Complete (430+ test cases)
+⚠️ **Native Bindings:** Need to be built
+⚠️ **WASM Module:** Need to be built
+
+## Building Packages
+
+### 1. Build Native Bindings (@ruvector/core)
+
+```bash
+# From project root
+cargo build --release
+
+# Build npm package
+cd npm/core
+npm install
+npm run build
+```
+
+### 2. Build WASM Module (@ruvector/wasm)
+
+```bash
+# Install wasm-pack if needed
+cargo install wasm-pack
+
+# Build WASM
+cd npm/wasm
+npm install
+npm run build:wasm
+```
+
+### 3. Build Main Package (ruvector)
+
+```bash
+cd npm/ruvector
+npm install
+npm run build
+```
+
+## Running Tests
+
+### Quick Test
+
+```bash
+# From npm directory
+npm test
+```
+
+### Test Options
+
+```bash
+# Unit tests only (fastest)
+npm run test:unit
+
+# Integration tests only
+npm run test:integration
+
+# Performance benchmarks (slowest)
+npm run test:perf
+
+# Specific package
+cd npm/tests
+node --test unit/core.test.js
+node --test unit/wasm.test.js
+node --test unit/ruvector.test.js
+```
+
+## What Gets Tested
+
+### @ruvector/core
+- Platform detection
+- Vector operations (insert, search, delete)
+- HNSW indexing
+- Distance metrics
+
+### @ruvector/wasm
+- WASM loading
+- API compatibility
+- Browser/Node detection
+
+### ruvector
+- Backend selection
+- Fallback logic
+- API consistency
+
+### CLI
+- All commands
+- Error handling
+- Output formatting
+
+## Expected Results
+
+When packages are built:
+- ✅ All tests should pass
+- ✅ ~470ms for unit tests
+- ✅ ~400ms for WASM tests
+- ⚡ Performance benchmarks show throughput metrics
+
+## Troubleshooting
+
+### "Cannot find module @ruvector/core"
+→ Build native bindings first (see step 1 above)
+
+### "WASM module not found"
+→ Build WASM module first (see step 2 above)
+
+### Tests are slow
+→ Run unit tests only: `npm run test:unit`
+→ Skip benchmarks (they're comprehensive)
+
+## Test Output Example

+## Expected Behavior
+
+### Test Skipping
+
+Tests automatically skip when dependencies are unavailable:

+- **CLI tests**: Skipped if dependencies not installed
+
+### Performance Expectations
+
+Minimum performance targets (may vary by backend):
+
+- **Insert**: >10 vectors/sec (single), >1000 vectors/sec (batch)
+- **Search**: >5 queries/sec
+- **Latency**: <1000ms average for k=10 searches
+- **Memory**: <5KB per vector (with overhead)
+
+## Test Results
+
+After running tests, check `test-results.json` for detailed results:
+
+```json
+{
+  "timestamp": "2024-01-01T00:00:00.000Z",
+  "summary": {
+    "total": 5,
+    "passed": 5,
+    "failed": 0,
+    "passRate": "100.0%"
+  },
+  "results": [...]
+}
+```
+
+## Prerequisites
+
+### For @ruvector/core tests:
+
+```bash
+# Build native bindings (from project root)
+cargo build --release
+npm run build:napi
+```
+
+### For @ruvector/wasm tests:
+
+```bash
+# Build WASM (requires wasm-pack)
+cd npm/wasm
+npm run build:wasm
+```
+
+### For all tests:
+
+```bash
+# Install dependencies for each package
+cd npm/core && npm install
+cd npm/wasm && npm install
+cd npm/ruvector && npm install
+```
+
+## Troubleshooting
+
+### "Cannot find module" errors
+
+- Ensure dependencies are installed: `npm install` in each package
+- Build packages first: `npm run build` in each package
+
+### "Native binding not available"
+
+- Build Rust crates first: `cargo build --release`
+- Check platform support: Currently supports linux-x64, darwin-arm64, etc.
+
+### "WASM module not found"
+
+- Build WASM: `cd npm/wasm && npm run build:wasm`
+- Install wasm-pack: `cargo install wasm-pack`
+
+### Tests timeout
+
+- Increase timeout for performance tests
+- Use `--perf` flag separately for benchmarks
+- Run individual test files for debugging
+
+## CI/CD Integration
+
+Add to your CI pipeline:
+
+```yaml
+# .github/workflows/test.yml
+- name: Run Tests
+  run: |
+    cd npm/tests
+    node run-all-tests.js
+```
+

+
+## Issues Found and Fixes
+
+### Issue 1: Package Location

+## Performance Benchmarks
+
+The performance test suite measures:
+
+### Throughput
+- Single insert operations
+- Batch insert (1K, 10K, 50K vectors)
+- Search queries per second
+- Concurrent search handling
+
+### Latency
+- Average search latency
+- P95 latency (95th percentile)
+- Dimension impact on latency
+
+### Scaling
+- Performance across dimensions (128, 384, 768, 1536)
+- Insert throughput vs. size
+- Search speed vs. index size
+
+### Memory
+- Per-vector memory usage
+- Total memory increase
+- Memory efficiency
+
+### Backend Comparison
+- Native vs WASM performance
+- Feature availability
+- Optimization impact
+
+## Next Steps
+
+### To Run Tests
+
+1. **Build native bindings:**
+   ```bash
+   cargo build --release

+
+3. **Build main package:**
+   ```bash
+   cd npm/ruvector && npm install && npm run build
+   ```
+
+4. **Run tests:**

+   cd npm && npm test
+   ```
+
+### For CI/CD
+
+Add test workflow (example in `TEST_RESULTS.md`)
+
+### For Development
+
+- Run `npm run test:unit` frequently during development
+- Run `npm run test:perf` before releases
+- Check `test-results.json` for detailed metrics
