Testing Overview

Comprehensive testing ensures the Reformer Platform is reliable, secure, and performs well. All code changes must be tested before deployment.

Testing Philosophy​

  1. Test Early, Test Often - Catch issues before they reach production
  2. Automate Everything - Manual testing is error-prone and slow
  3. Test in Production-Like Environment - Staging should mirror production
  4. Security Testing is Mandatory - Never skip security tests
  5. Document Test Results - Track what was tested and results

Testing Types​

Unit Tests​

  • Test individual functions and modules
  • Fast, isolated, deterministic
  • Run on every commit

Integration Tests​

  • Test how components work together
  • Test API endpoints
  • Test database interactions

End-to-End (E2E) Tests​

  • Test complete user workflows
  • Test in real browser environment
  • Test critical user paths

Security Tests​

  • Test for vulnerabilities
  • Test authentication/authorization
  • Test input validation
  • See Security Testing for details

Performance Tests​

  • Test response times
  • Test under load
  • Test resource usage

Testing Requirements​

Before Every Commit​

  • Unit tests pass
  • Linter passes
  • No console.log statements
  • Code follows style guide

Before Every PR​

  • All tests pass
  • Integration tests pass
  • Security tests pass
  • Code review completed

Before Every Deployment​

  • All tests pass
  • E2E tests pass
  • Performance tests pass
  • Manual smoke tests completed

Test Coverage Goals​

  • Unit Tests: 80%+ coverage
  • Integration Tests: All API endpoints
  • E2E Tests: Critical user flows
  • Security Tests: All user input points

Quick Reference​

Running Tests​

Local Development​

# Run all tests
npm test

# Run specific test suite
npm run test:unit
npm run test:integration
npm run test:e2e
npm run test:security

# Run with coverage
npm run test:coverage

# Watch mode
npm run test:watch

CI/CD​

Tests run automatically:

  • On every commit (unit tests)
  • On pull requests (all tests)
  • Before deployment (full test suite)

Test Environment​

Development​

  • Local database
  • Mock external services
  • Fast feedback

Staging​

  • Production-like database
  • Real external services (test mode)
  • Full integration testing

Production​

  • Real database
  • Real external services
  • Monitoring and alerting

Test Data Management​

  • Use fixtures for consistent test data
  • Clean up after tests
  • Never use production data in tests
  • Anonymize any real data used

Reporting Test Results​

Document:

  • What was tested
  • Test results (pass/fail)
  • Coverage metrics
  • Performance metrics
  • Issues found
