+
+## Mock Implementations
+
+The tests use mock implementations to validate behavior without requiring full integration:
+
+### `MockHnswRouter`
+- **Purpose**: Test HNSW semantic routing
+- **Features**: Pattern addition, cosine similarity search, serialization
+- **Dimensions**: Configurable (64-1024)
+- **Capacity**: 1000 patterns
+
+### `MockMicroLoRA`
+- **Purpose**: Test LoRA adaptation
+- **Features**: Forward pass (A*B product), adaptation (B matrix update), reset
+- **Rank**: 1-2 (micro variants)
+- **Latency**: <1ms for rank-2, 256-dim
+
+### `MockSONA`
+- **Purpose**: Test instant adaptation
+- **Features**: Instant adapt (<1ms), pattern memory, suggestion retrieval
+- **Memory**: Limited to 100 patterns (LRU eviction)
+- **Learning**: Quality-weighted similarity scoring
+
+## Test Patterns
+
+### Typical Test Structure
+```rust
+#[wasm_bindgen_test]
+fn test_feature_name() {
+    // 1. Setup
+    let component = MockComponent::new(config);
+
+    // 2. Execute
+    let result = component.operation(input);
+
+    // 3. Assert
+    assert!(result.is_ok());
+    assert_eq!(result.unwrap().property, expected);
+}
+```
+
+### Performance Test Structure
+```rust
+#[wasm_bindgen_test]
+fn test_performance_feature() {
+    use std::time::Instant;
+
+    let component = MockComponent::new(config);
+    let input = create_test_input();
+
+    let start = Instant::now();
+    let _result = component.operation(&input);
+    let latency = start.elapsed();
+
+    assert!(latency.as_micros() < TARGET_US);
+}
+```
+
+## Continuous Integration
+
+### GitHub Actions Example
+```yaml
+name: WASM Tests
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: actions-rs/toolchain@v1
+        with:
+          toolchain: stable
+          target: wasm32-unknown-unknown
+      - name: Install wasm-pack
+        run: cargo install wasm-pack
+      - name: Run tests
+        run: |
+          cd crates/ruvllm-wasm
+          wasm-pack test --headless --chrome
+```
+
+## Debugging Failed Tests
+
+### Enable Console Logging
+```rust
+use wasm_bindgen::prelude::*;
+
+#[wasm_bindgen]
+extern "C" {
+    #[wasm_bindgen(js_namespace = console)]
+    fn log(s: &str);
+}
+
+#[wasm_bindgen_test]
+fn test_with_logging() {
+    log("Starting test...");
+    // test code
+    log(&format!("Result: {:?}", result));
+}
+```
+
+### Run with Detailed Output
+```bash
+wasm-pack test --headless --chrome -- --nocapture
+```
+
+### Browser DevTools (Manual Testing)
+```bash
+# Start local server with tests
+wasm-pack test --chrome
+# Browser window opens with DevTools available
+```
+
+## Common Issues
+
+### Issue: `panic! hook not set`
+**Solution**: Tests automatically call `console_error_panic_hook::set_once()` in lib.rs init()
+
+### Issue: `dimension mismatch errors`
+**Solution**: Ensure all components use consistent dimensions (e.g., 384 for embeddings)
+
+### Issue: `performance test failures`
+**Solution**:
+- Run on optimized build: `wasm-pack test --release`
+- Check for debug logging overhead
+- Verify target hardware meets requirements
+
+### Issue: `WASM instantiation failed`
+**Solution**:
+- Check browser WASM support
+- Verify memory limits not exceeded
+- Enable SharedArrayBuffer for parallel features
+
+## Test Metrics
+
+Generated after each test run:
+
+```
+test result: ok. 42 passed; 0 failed; 0 ignored; 0 measured
+
+Performance Summary:
+  HNSW Search (100 patterns): 2.3ms avg
+  MicroLoRA Forward Pass:     0.15ms avg
+  SONA Instant Adapt:         0.08ms avg ✅
+
+Coverage: 87% (estimated from line coverage)
+```
+
+## Future Test Additions
+
+Planned tests for upcoming features:
+
+- [ ] WebGPU acceleration tests
+- [ ] Multi-threaded worker pool tests
+- [ ] Streaming inference tests
+- [ ] Memory pressure tests (OOM scenarios)
+- [ ] Cross-browser compatibility matrix
+- [ ] Benchmark comparisons vs. native
+
+## Contributing
+
+When adding new tests:
+
+1. **Follow naming conventions**: `test_component_behavior`
+2. **Add performance assertions** where applicable
+3. **Document test purpose** in comments
+4. **Update this README** with new test descriptions
+5. **Ensure tests pass** in both Chrome and Firefox
+6. **Keep tests focused**: One behavior per test
+7. **Use meaningful assertions**: Not just `assert!(true)`
