Test Directory Structure

This directory contains all tests for the CIM Document Processor backend.

Directory Structure

• unit/ - Unit tests for individual functions and classes
• integration/ - Integration tests for service interactions
• utils/ - Test utilities and helpers
• mocks/ - Mock implementations for external services

Running Tests

# Run all tests
npm test

# Run tests in watch mode
npm run test:watch

# Run tests with coverage
npm run test:coverage

Test Guidelines

• Write tests for critical paths first: document upload, authentication, core API endpoints
• Use TDD approach: write tests first, then implementation
• Mock external services (Firebase, Supabase, LLM APIs)
• Use descriptive test names that explain what is being tested
• Group related tests using describe blocks

Example Test Structure

import { describe, it, expect, beforeEach, vi } from 'vitest';

describe('ServiceName', () => {
  beforeEach(() => {
    // Setup
  });

  it('should handle success case', () => {
    // Test implementation
  });

  it('should handle error case', () => {
    // Test implementation
  });
});
