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);
}

Continuous Integration

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

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)
