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
#[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
#[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);
}

Debugging Failed Tests
Enable Console Logging
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
wasm-pack test --headless --chrome -- --nocapture
Browser DevTools (Manual Testing)
# 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

Contributing
When adding new tests:
- Follow naming conventions:
test_component_behavior - Add performance assertions where applicable
- Document test purpose in comments
- Update this README with new test descriptions
- Ensure tests pass in both Chrome and Firefox
- Keep tests focused: One behavior per test
- Use meaningful assertions: Not just
assert!(true)
