CeloHT Testing Strategy

Version: 1.0 Project: CeloHT

---

1. Purpose

This document defines the testing strategy for CeloHT software, APIs, databases, blockchain integrations, and smart contracts.

The objective is to identify defects before they reach production and reduce security and reliability risks.

2. Testing Pyramid

                 E2E Tests
                    ▲
                   / \
                  /   \
             Integration
                Testing
                /     \
               /       \
          Unit Tests
         /             \
        /               \
       Static Analysis

The majority of tests should be fast, deterministic unit tests.

---

3. Testing Layers

CeloHT testing may include:

1. Static analysis
2. Unit testing
3. Component testing
4. Integration testing
5. API testing
6. Database testing
7. Smart-contract testing
8. Blockchain integration testing
9. End-to-end testing
10. Security testing
11. Performance testing

---

4. Static Analysis

Static analysis should identify:

• Type errors
• Lint problems
• Unsafe patterns
• Dependency vulnerabilities
• Code-quality issues

Typical checks:

npm run lint
npx tsc --noEmit

---

5. Unit Testing

Unit tests verify isolated logic.

Examples:

• Amount calculations
• Validation
• Formatting
• Authorization rules
• Utility functions
• Business logic

Unit tests should be:

• Fast
• Deterministic
• Independent

---

6. Component Testing

Frontend components should be tested for:

• Rendering
• User interaction
• State changes
• Error states
• Accessibility

Important wallet-related components should also test rejected transactions.

---

7. API Testing

API tests should verify:

• Valid requests
• Invalid requests
• Authentication
• Authorization
• Rate limits
• Error responses
• Database integration
• Blockchain integration

---

8. Database Testing

Database tests should verify:

• Constraints
• Relationships
• Queries
• Migrations
• Authorization policies
• Data integrity

---

9. Smart Contract Testing

Smart contracts require extensive testing.

Test categories include:

Functional

Does the contract perform intended operations?

Access Control

Can unauthorized accounts perform restricted actions?

Edge Cases

What happens with:

• Zero values
• Maximum values
• Invalid addresses
• Repeated operations
• Unexpected states

Failure Tests

Does the contract fail safely?

---

10. Smart Contract Security Testing

Where appropriate, test for:

• Reentrancy
• Access-control failures
• Arithmetic errors
• State manipulation
• Unsafe external calls
• Unexpected token behavior

---

11. Blockchain Integration Testing

Test:

Wallet Connection
      │
      ▼
Network Detection
      │
      ▼
Transaction Creation
      │
      ▼
User Signature
      │
      ▼
Broadcast
      │
      ▼
Confirmation
      │
      ▼
Application Update

Also test:

• Rejected signatures
• Failed transactions
• RPC failures
• Network mismatch
• Insufficient gas
• Incorrect contract address

---

12. End-to-End Testing

E2E tests should verify complete user workflows.

Example:

User
 │
 ▼
Open Application
 │
 ▼
Connect Wallet
 │
 ▼
Select Service
 │
 ▼
Submit Transaction
 │
 ▼
Confirm Wallet
 │
 ▼
Blockchain Confirmation
 │
 ▼
Application Displays Result

---

13. Security Testing

Security testing should include:

• Authentication testing
• Authorization testing
• Input validation
• Dependency scanning
• Secret scanning
• Security headers
• Contract security analysis

---

14. Performance Testing

Performance tests may evaluate:

• API latency
• Database queries
• Frontend loading
• Blockchain RPC latency
• Concurrent requests

Performance targets should be defined based on actual product requirements.

---

15. Regression Testing

Every significant bug should be considered for a regression test.

Bug Found
   │
   ▼
Fix
   │
   ▼
Regression Test
   │
   ▼
CI

---

16. CI Testing

Pull requests should automatically run appropriate checks.

Conceptual pipeline:

Pull Request
     │
     ▼
Install
     │
     ▼
Lint
     │
     ▼
Type Check
     │
     ▼
Unit Tests
     │
     ▼
Integration Tests
     │
     ▼
Build
     │
     ▼
Security Checks

---

17. Test Environments

Testing should use separate environments:

Local
  │
  ▼
CI
  │
  ▼
Testnet / Staging
  │
  ▼
Production

Production should not be used as a test environment.

---

18. Test Data

Test data should be synthetic whenever possible.

Never use:

• Real private keys
• Real passwords
• Sensitive production records
• Production secrets

---

19. Test Coverage

Coverage is useful but is not the only quality metric.

A high coverage percentage does not guarantee secure software.

Priority should be given to:

• Critical business logic
• Financial operations
• Authorization
• Security controls
• Smart contracts
• Data integrity

---

20. Release Gate

A release should normally require:

[ ] Tests pass
[ ] Lint passes
[ ] Type check passes
[ ] Build succeeds
[ ] Security checks pass
[ ] Critical issues resolved
[ ] Documentation updated

---

21. Testing Principle

Test the expected path, the failure path, and the malicious path.
