E2E Tests

This directory contains end-to-end tests for the OpenRouter SDK.

Prerequisites

  1. Install dependencies:

    npm install

  2. Set up your OpenRouter API key:

    export OPENROUTER_API_KEY=your_api_key_here

    Or create a .env file in the project root:

    OPENROUTER_API_KEY=your_api_key_here

Running Tests

Run all tests:

npm test

Run only e2e tests:

npm run test:e2e

Run tests in watch mode:

npm run test:watch

Test Coverage

The e2e test suite includes:

Models Tests (models.test.ts)

  • Fetching the list of available models
  • Validating model properties
  • Filtering models by category
  • Getting the total count of models

Chat Tests (chat.test.ts)

  • Non-streaming mode:

    • Sending chat requests and receiving responses
    • Multi-turn conversations
    • Token limit enforcement

  • Streaming mode:

    • Streaming chat responses
    • Progressive content delivery
    • Finish reason detection

Beta Responses Tests (responses.test.ts)

  • Testing the beta responses endpoint
  • Note: This endpoint is in alpha/beta and may require updates

Notes

  • Tests make real API calls to OpenRouter, so you need a valid API key
  • Tests may consume API credits
  • Some tests use the openai/gpt-3.5-turbo model by default
  • The beta responses endpoint has limited test coverage as it's still in development
