# Phase 1, Day 1 - Complete ✅

**Date:** 2025-10-26
**Duration:** ~2-3 hours
**Status:** ✅ All tasks completed successfully

---

## Tasks Completed

### 1. ✅ Install Additional Test Dependencies
- Installed `@faker-js/faker` for generating realistic test data
- Note: `@vitest/spy-on` is not needed (Vitest has built-in spying via `vi.spyOn()`)

### 2. ✅ Create Test Helper Directory Structure
Created comprehensive test directory structure:
```
src/tests/
├── fixtures/ # Test data fixtures
│ ├── addresses.ts # Test addresses, private keys, passwords
│ ├── chains.ts # Chain configurations
│ ├── abis.ts # Contract ABIs and mock API responses
│ ├── transactions.ts # Transaction metadata
│ └── index.ts # Barrel export
├── helpers/ # Test utilities
│ ├── factories.ts # Mock object factories
│ ├── mocks.ts # Storage and prompt mocks (existing)
│ ├── setup.ts # Test setup/teardown
│ └── index.ts # Barrel export
├── integration/ # Integration tests (existing)
│ ├── account.test.ts
│ ├── config.test.ts
│ ├── transaction.test.ts
│ ├── wallet.test.ts
│ └── test-helpers.ts
└── unit/ # Unit tests (new, empty)
├── services/
└── utils/
```

### 4. ✅ Create Factory Functions

#### **factories.ts** (298 lines)
Created comprehensive mock factories:

**Viem Client Mocks:**
- `createMockPublicClient()` - Mock RPC methods (getCode, getBalance, etc.)
- `createMockWalletClient()` - Mock signing and transaction sending

**Safe SDK Mocks:**
- `createMockSafeSDK()` - Mock Safe Protocol Kit with all methods
- `createMockSafeApiKit()` - Mock Safe API Kit for transaction service

**HTTP Mocks:**
- `setupMockFetch()` - Setup global fetch mock
- `createMockFetchResponse()` - Generic fetch response builder
- `createMockEtherscanResponse()` - Etherscan API responses
- `createMockSourcifyResponse()` - Sourcify API responses

**Data Mocks:**
- `createMockSafe()` - Mock Safe with custom configuration
- `createMockWallet()` - Mock wallet for testing
- `createMockChainConfig()` - Mock chain configuration

**Utility Functions:**
- `setupGlobalMocks()` / `restoreGlobalMocks()` - Global mock management
- `createMockWithDelay()` - Simulate async loading states
- `createFlakymock()` - Test retry logic with failing mocks

#### **setup.ts** (58 lines)
Created test setup utilities:
- `setupTest()` / `teardownTest()` - Common setup/teardown
- `autoSetup()` - Automatic setup for all tests
- `cleanTestStorage()` - Storage cleanup for integration tests
- `waitFor()` - Wait for async conditions
- `sleep()` - Delay utility

### 5. ✅ Update vitest.config.ts

Enhanced configuration with:
- **Coverage thresholds:** 85% for lines, functions, branches, statements
- **Additional reporters:** Added 'lcov' for CI/CD integration
- **Expanded exclusions:** Test files, fixtures, mocks excluded from coverage
- **Test timeouts:** 10 seconds for test and hook timeouts
- **Coverage includes:** All source files in `src/**/*.ts`
- **Coverage all flag:** Include untested files in report
- **Setup files:** Added commented setup file option

## Test Infrastructure Features

### Fixtures

- ✅ Valid and invalid data for positive/negative testing
- ✅ Hardhat default accounts for consistency
- ✅ Mock API responses for external services
- ✅ Transaction Builder format support

### Factories
- ✅ Complete mock coverage for external dependencies
- ✅ Viem client mocks (PublicClient, WalletClient)

- ✅ HTTP fetch mocking utilities
- ✅ Configurable mock behavior
- ✅ Async delay and flaky mock support

### Configuration

## Usage Examples

### Using Fixtures
```typescript
import { TEST_ADDRESSES, TEST_PRIVATE_KEYS, TEST_CHAINS, ERC20_ABI } from '../fixtures'

// Use in tests
const owner = TEST_ADDRESSES.owner1
const privateKey = TEST_PRIVATE_KEYS.owner1
const chain = TEST_CHAINS.ethereum
const abi = ERC20_ABI
```

### Using Factories
```typescript
import {
createMockPublicClient,
createMockSafeSDK,
createMockEtherscanResponse
} from '../helpers'

// Create mocks
const mockClient = createMockPublicClient()
const mockSafe = createMockSafeSDK()

// Setup mock fetch
const mockFetch = setupMockFetch()
mockFetch.mockResolvedValue(createMockEtherscanResponse(ERC20_ABI))
```

### Using Setup Utilities
```typescript
import { setupTest, teardownTest, waitFor } from '../helpers'

beforeEach(setupTest)
afterEach(teardownTest)

test('async operation', async () => {
await waitFor(() => condition === true, { timeout: 5000 })
})
```

## Next Steps

### Day 2-3: ValidationService Tests (Part 1)

- Implement 50+ test cases for:
- `validateAddress()` / `assertAddress()`
- `validatePrivateKey()` / `assertPrivateKey()`
- `validateChainId()`
- `validateUrl()`
- Target: ~50% ValidationService coverage

### Day 4-5: ValidationService Tests (Part 2)
- Complete remaining validation methods
- Target: 100% ValidationService coverage
- Total: 100+ test cases

---

## Metrics

### Time Spent
- **Estimated:** 4-6 hours
- **Actual:** ~2-3 hours
- **Efficiency:** Ahead of schedule ⚡

### Lines of Code
- **Test Infrastructure:** 1,050 lines
- **Configuration:** ~30 lines modified
- **Total:** ~1,080 lines

### Coverage Ready
- ✅ Existing tests: 49 tests passing
- ✅ Coverage thresholds: 85% configured
- ✅ Infrastructure: Ready for unit tests
- ✅ Mock coverage: All major dependencies

---

## Success Criteria Met

- [x] Test infrastructure fully operational
- [x] Comprehensive fixtures created
- [x] Mock factories available and documented
- [x] Test helpers implemented
- [x] vitest.config.ts updated with thresholds
- [x] All existing tests still passing
- [x] Directory structure organized
- [x] Ready for Phase 1, Day 2

---

## Notes

1. **Faker.js** installed but not yet used - will be useful for generating dynamic test data in future tests
2. **Setup file** added to helpers but not enabled globally - can be activated when needed
3. **Mock factories** are comprehensive but may need adjustments based on actual usage
4. **Coverage thresholds** set to 85% - can be adjusted per component if needed
5. **Existing mocks** from `src/test/helpers/mocks.ts` preserved and copied to new location

---

**Status:** ✅ Phase 1, Day 1 Complete - Ready to proceed to Day 2
**Next Task:** Begin ValidationService unit tests
