Overview

Build a full test suite and benchmark harness to validate correctness and measure performance vs Pinchtab/Pathik.

Tasks

• Unit tests:
  • CDP client: message framing, response parsing, error handling
  • Snapshot builder: filter, depth, format, diff modes
  • Markdown converter: headings, lists, tables, code blocks, links
  • URL validator: private IPs, schemes, edge cases
  • Rate limiter: token bucket correctness
  • JSON response helpers
• Integration tests:
  • Full server start → navigate → snapshot → action flow
  • Crawl pipeline: fetch → extract → convert → save
  • Tab lifecycle: create → use → close → clean stale
• Benchmarks:
  • Snapshot generation latency (target: <100ms for typical page)
  • JSON serialization throughput
  • Crawl pipeline throughput (URLs/sec)
  • Memory usage per request (target: <5MB arena)
  • Compare vs Pinchtab Go and Pathik Go baselines
• Mock Chrome CDP server for offline testing

Acceptance Criteria

• 80% code coverage on core modules

• All benchmarks have baseline numbers documented
• Tests pass without requiring a running Chrome instance (via mocks)
• CI-friendly: zig build test runs all tests
