# Contact Import Testing Implementation

## Overview

This document describes the comprehensive test suite implemented for Time Safari's
contact import functionality. The tests cover all scenarios mentioned in the
original TODO comment and provide thorough validation of the contact import feature.

## Test File: `45-contact-import.spec.ts`

### Test Coverage

The test suite covers all the requirements from the original TODO:

1. ✅ **Contact import via URL query parameters**
   - Single contact import: `/contact-import?contacts=[{"did":"did:example:123","name":"Alice"}]`
   - Multiple contacts import with proper encoding
   - URL parameter validation and error handling

2. ✅ **JWT import via URL path**
   - JWT token in URL: `/contact-import/[JWT_TOKEN]`
   - Deep link support: `/deep-link/contact-import/[JWT_TOKEN]`
   - JWT payload validation and parsing

3. ✅ **Manual JWT input via textarea**
   - Direct JWT string input
   - Raw contact data input
   - Input validation and error handling

4. ✅ **Duplicate contact detection and field comparison**
   - Existing contact detection
   - Field-by-field comparison display
   - Modified contact handling

5. ✅ **Error scenarios**
   - Invalid JWT format detection
   - Malformed contact data validation
   - Missing required fields handling
   - Wrong data types validation
   - Network error simulation

6. ✅ **Error logging verification**
   - Console error message validation
   - UI error message display verification
   - Error state handling

### Test Scenarios

#### Basic Import Tests

- **Single contact via URL**: Tests basic URL parameter import
- **Multiple contacts via URL**: Tests bulk import functionality
- **JWT path import**: Tests JWT token in URL path
- **Deep link import**: Tests deep link redirect functionality
- **Manual JWT input**: Tests textarea JWT input
- **Manual contact data input**: Tests raw JSON input

#### Advanced Functionality Tests

- **Duplicate detection**: Tests existing contact identification
- **Field comparison**: Tests difference display for modified contacts
- **Selective import**: Tests checkbox selection functionality
- **Visibility settings**: Tests activity visibility controls
- **Mixed new/existing**: Tests combination scenarios
- **Large import performance**: Tests performance with 10+ contacts

#### Error Handling Tests

- **Invalid JWT format**: Tests malformed JWT handling
- **Empty contact array**: Tests empty data handling
- **Missing required fields**: Tests incomplete data validation
- **Wrong data types**: Tests type validation
- **Network error simulation**: Tests network failure handling

### Test Data

#### Valid Test Contacts

```typescript
const TEST_CONTACTS = {
  alice: {
    did: 'did:ethr:0x111d15564f824D56C7a07b913aA7aDd03382aA39',
    name: 'Alice Test',
    publicKey: 'alice-public-key-123'
  },
  bob: {
    did: 'did:ethr:0x222BB77E6Ff3774d34c751f3c1260866357B677b',
    name: 'Bob Test',
    publicKey: 'bob-public-key-456'
  },
  charlie: {
    did: 'did:ethr:0x333CC88F7Gg488e45d862f4d237097f748C788c',
    name: 'Charlie Test',
    publicKey: 'charlie-public-key-789'
  }
};
```

#### Invalid Test Data

```typescript
const INVALID_DATA = {
  malformedJwt: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.invalid.payload',
  emptyArray: '[]',
  missingFields: '[{"name":"Incomplete Contact"}]',
  wrongTypes: '[{"did":123,"name":456}]',
  networkError: 'http://invalid-url-that-will-fail.com/contacts'
};
```

### Utility Functions Added

#### New Functions in `testUtils.ts`

- `createTestJwt(payload)`: Creates test JWT tokens
- `cleanupTestContacts(page, contactNames)`: Cleans up test contacts
- `addTestContact(page, did, name, publicKey?)`: Adds a test contact
- `verifyContactExists(page, name)`: Verifies contact exists
- `verifyContactCount(page, expectedCount)`: Verifies contact count

### Test Execution

#### Running Individual Tests

```bash
# Run all contact import tests
npm run test:playwright -- 45-contact-import.spec.ts

# Run specific test
npm run test:playwright -- 45-contact-import.spec.ts -g "Import single contact"
```

#### Test Environment Requirements

- Clean database state before each test
- Test user (User 00) imported
- No existing test contacts
- Proper network connectivity for deep link tests

### Key Selectors Used

```typescript
// Import functionality
'button:has-text("Import Selected Contacts")'
'textarea[placeholder="Contact-import data"]'
'button:has-text("Check Import")'

// Contact list
'li[data-testid="contactListItem"]'
'h2:has-text("Contact Name")'

// Alert dialogs
'div[role="alert"]'
'span:has-text("Success")'
'button > svg.fa-xmark'

// Import status
'li:has-text("New")'
'li:has-text("Existing")'
'span:has-text("the same as")'
```

### Error Handling Validation

The tests verify proper error handling for:

- Invalid JWT tokens
- Malformed contact data
- Missing required fields
- Network failures
- Duplicate contact scenarios
- Empty or invalid input

### Performance Considerations

- Tests include large contact list performance validation
- Proper cleanup to prevent test interference
- Efficient contact management utilities
- Resource-intensive test classification

### Integration with Existing Tests

The contact import tests integrate with:

- Existing contact management tests (`40-add-contact.spec.ts`)
- User management utilities (`testUtils.ts`)
- Platform service testing infrastructure
- Database migration testing framework

### Security Considerations

- JWT token validation testing
- Input sanitization verification
- Error message security (no sensitive data exposure)
- Network request validation

## Migration Status

This test implementation addresses the TODO comment requirements:

```
// TODO: Testing Required - Database Operations + Logging Migration to PlatformServiceMixin
// Priority: Medium | Migrated: 2025-07-06 | Author: Matthew Raymer
```

**Status**: ✅ **COMPLETED** - August 4, 2025

All 6 testing requirements have been implemented with comprehensive coverage:

1. ✅ Contact import via URL
2. ✅ JWT import via URL path
3. ✅ Manual JWT input
4. ✅ Duplicate contact detection
5. ✅ Error scenarios
6. ✅ Error logging verification

## Future Enhancements

Potential improvements for the test suite:

- Real JWT signing for more authentic testing
- Network interception for better error simulation
- Performance benchmarking metrics
- Cross-platform compatibility testing
- Accessibility testing for import interfaces
