This directory contains tests for the Email Agent application. The tests are organized by feature and use Jest as the testing framework.

• email-summarizer.test.js: Tests for the email summarization functionality
• process-summaries-api.test.js: Tests for the process-summaries API endpoint
• run-tests.js: A custom test runner script that runs all tests

You can run the tests using the following npm scripts:

# Run all tests
npm test

# Run tests in watch mode (automatically re-run when files change)
npm run test:watch

# Run only the API tests
npm run test:api

# Run only the email summarizer tests
npm run test:summarizer

The tests are designed to be resilient to different environments:

• If running in a CI environment without API keys, the OpenAI API tests will be skipped
• If the server is not running, the API tests will be skipped
• Tests have appropriate timeouts for API calls

To add a new test file:

1. Create a new file in the tests directory with the .test.js extension
2. Use the Jest testing framework (describe, test, expect, etc.)
3. Run the tests to make sure they work

• Keep tests focused on a single feature or component
• Use descriptive test names that explain what is being tested
• Mock external dependencies when possible
• Handle API keys and other secrets securely
• Add appropriate error handling and skipping logic for different environments
