Running Tests

The server must be running on port 8080 before running tests.
Run the complete test suite: 
# Start server in one terminal
npm start

# Run tests in another terminal
npm test

​
Individual Test Suites

You can run specific test suites individually: 
npm run test:signatures    # Thinking signatures
npm run test:multiturn     # Multi-turn with tools
npm run test:streaming     # Streaming SSE events
npm run test:interleaved   # Interleaved thinking
npm run test:images        # Image processing
npm run test:caching       # Prompt caching
npm run test:strategies    # Account selection strategies
npm run test:cache-control # Cache control field stripping
npm run test:crossmodel    # Cross-model thinking signatures
npm run test:oauth         # OAuth no-browser mode

​
Test Coverage

The test suite covers:
  • Thinking Signatures: Validates thinking block signatures for Claude and Gemini models
  • Multi-turn Conversations: Tests tool use and multi-turn dialogue flows
  • Streaming: Verifies Server-Sent Events (SSE) streaming functionality
  • Interleaved Thinking: Tests thinking blocks interspersed with content
  • Image Processing: Validates image input handling and conversion
  • Prompt Caching: Tests cache_read_input_tokens and session ID continuity
  • Account Strategies: Unit tests for sticky, round-robin, and hybrid strategies
  • Cache Control: Ensures cache_control fields are properly stripped from requests
  • Cross-Model Switching: Validates signature handling when switching between Claude and Gemini
  • OAuth: Tests headless OAuth flow with manual code input

​
Test Architecture

  • Tests are CommonJS files (.cjs) located in the tests/ directory
  • They make HTTP requests to the local proxy server
  • Shared test utilities are in tests/helpers/http-client.cjs
  • Test runner supports filtering: node tests/run-all.cjs <filter>

​
Strategy Unit Tests

Strategy tests don’t require a running server: 
node tests/test-strategies.cjs
These tests validate the account selection logic for all three strategies (sticky, round-robin, hybrid).
