Testing

This document describes the testing strategy used throughout the CeloHT ecosystem.

Testing is essential to ensure that every release is secure, reliable, and production-ready.

---

Philosophy

CeloHT follows a test-first mindset.

Every new feature, bug fix, or improvement should be validated through automated and manual testing before being merged.

Our goals are:

• Reliability
• Security
• Stability
• Performance
• Maintainability

Testing Pyramid

                 Manual Testing
                      ▲
             Integration Tests
                      ▲
                Unit Tests

Unit tests should represent the majority of all tests.

---

Types of Tests

Unit Tests

Unit tests verify individual functions and components.

Examples:

• Utility functions
• React components
• Smart contract methods
• API services

Example:

npm test

---

Integration Tests

Integration tests verify that multiple components work correctly together.

Examples:

• Wallet connection
• Smart contract interaction
• Database communication
• API requests

---

End-to-End (E2E) Tests

E2E tests simulate real user behavior.

Examples:

• Connect wallet
• Register an agent
• Complete an education course
• Submit a governance vote

Recommended tools:

• Playwright
• Cypress

---

Smart Contract Tests

Every smart contract must include automated tests.

Example:

npx hardhat test

Tests should verify:

• Expected behavior
• Access control
• Edge cases
• Invalid inputs
• Security protections

---

Security Testing

Security testing includes:

• Static analysis
• Dependency scanning
• Secret detection
• Access control validation
• Smart contract vulnerability testing

Recommended tools:

• Slither
• Mythril
• OpenZeppelin Defender
• GitHub Advanced Security

---

Performance Testing

Performance tests measure:

• API response time
• Page load time
• Database performance
• Smart contract gas usage

---

Accessibility Testing

The CeloHT platform should follow accessibility best practices.

Areas to verify:

• Keyboard navigation
• Screen reader compatibility
• Color contrast
• Responsive layouts
• Form accessibility

---

Test Coverage

Recommended minimum coverage:

Area	Coverage
Utilities	95%
Components	90%
Services	90%
Smart Contracts	100%
API	90%

---

Running Tests

Run all tests

npm test

Run coverage

npm run coverage

Run smart contract tests

npx hardhat test

Run E2E tests

npm run test:e2e

---

Continuous Integration

Every Pull Request automatically runs:

• Dependency installation
• Type checking
• Linting
• Unit tests
• Smart contract tests
• Build verification
• Security checks

A Pull Request cannot be merged if any required check fails.

---

Manual Testing Checklist

Before every release verify:

• Wallet connection
• Navigation
• Responsive design
• Forms
• Documentation links
• Smart contract interactions
• Transaction confirmation
• Error handling

---

Bug Reporting

A good bug report should include:

• Environment
• Browser
• Operating System
• Steps to reproduce
• Expected behavior
• Actual behavior
• Screenshots (if applicable)
• Logs (if available)

---

Best Practices

• Write tests before fixing bugs.
• Keep tests independent.
• Avoid flaky tests.
• Test edge cases.
• Use meaningful test names.
• Maintain high code coverage.
• Review failing tests before merging.

---

Future Improvements

Planned enhancements include:

• Visual regression testing
• Load testing
• Chaos engineering
• AI-assisted test generation
• Cross-browser automation
• Mobile device testing
• Continuous performance monitoring

---

Conclusion

Testing is a core part of the CeloHT development process.

Every contributor shares responsibility for delivering secure, reliable, and high-quality software that supports the project's mission of financial inclusion, education, and sustainable development.
