Phase 4: End-to-End Tests Implementation

[devin-ai-integration]

End-to-End Tests Implementation Plan

Parent issue: #517

Overview

This issue tracks the implementation of end-to-end tests, focusing on critical user flows and full system integration.

Test Scope

User Flows

Test coverage needed for:

• Page navigation
• Data display
• User interactions
• Mobile responsiveness
• Error scenarios

Test Cases to Implement

1. Critical User Flows

• Test homepage loading and navigation
• Test stamp viewing and interaction
• Test transaction creation flow
• Test wallet integration
• Test mobile responsive behavior

2. Data Integration

• Test data loading and display
• Test data persistence
• Test cache behavior
• Test real-time updates

3. Error Scenarios

• Test network errors
• Test invalid data handling
• Test recovery flows
• Test user feedback

4. Mobile Testing

• Test responsive layouts
• Test touch interactions
• Test orientation changes
• Test different screen sizes

Implementation Guidelines

1. Follow Deno Fresh patterns
2. Test real user scenarios
3. Focus on mobile-first approach
4. Include error recovery paths

Test File Structure

// Example test structure for /tests/e2e/userFlows.test.ts

import { assertEquals } from '@std/assert';

Deno.test('User Flow - Stamp Viewing', async (t) => {
  await t.step('loads stamp details correctly', () => {
    // Test implementation
  });

  await t.step('handles mobile interaction', () => {
    // Test implementation
  });
});

Success Criteria

• All test cases implemented
• Tests pass consistently
• Mobile flows verified
• Documentation updated
• PR review completed

Dependencies

• Requires completion of Phase 1 (Utility Tests)
• Requires completion of Phase 2 (Component Tests)
• Requires completion of Phase 3 (API Tests)

Detailed Test Flow for API Integration Tests

Test Flow Structure

1. API Endpoint Tests

// File: /tests/api/endpoints/stamps.test.ts

import { assertEquals } from '@std/assert';
import { handler } from '../../../routes/api/stamps/[id].ts';

Deno.test('Stamps API Endpoints', async (t) => {
  // Test Group 1: Successful Responses
  await t.step('returns stamp data correctly', async () => {
    const response = await handler({
      params: { id: 'valid-stamp-id' }
    });
    assertEquals(response.status, 200);
    const data = await response.json();
    assertEquals(data.id, 'valid-stamp-id');
  });

  // Test Group 2: Error Responses
  await t.step('handles invalid stamp id', async () => {
    const response = await handler({
      params: { id: 'invalid-id' }
    });
    assertEquals(response.status, 404);
  });

  // Test Group 3: Headers
  await t.step('includes correct headers', async () => {
    const response = await handler({
      params: { id: 'valid-stamp-id' }
    });
    assertEquals(response.headers.get('Content-Type'), 'application/json');
  });
});

2. Data Validation Tests

// File: /tests/api/validation.test.ts

Deno.test('API Data Validation', async (t) => {
  // Test Group 1: Input Validation
  await t.step('validates query parameters', async () => {
    // Test parameter validation
  });

  // Test Group 2: Request Body
  await t.step('validates request body', async () => {
    // Test body validation
  });

  // Test Group 3: Sanitization
  await t.step('sanitizes user input', async () => {
    // Test input sanitization
  });
});

3. Integration Flow Tests

// File: /tests/api/integration/stamps.test.ts

Deno.test('Stamps API Integration', async (t) => {
  // Test Group 1: Data Flow
  await t.step('maintains data consistency', async () => {
    // Test data flow between endpoints
  });

  // Test Group 2: Cache
  await t.step('uses cache correctly', async () => {
    // Test cache behavior
  });

  // Test Group 3: Database
  await t.step('interacts with database', async () => {
    // Test database operations
  });
});

Test Execution Flow

1. Setup test environment:

   • Configure test database
   • Setup mock services
   • Prepare test data

2. Run test suites in order:
   a. API endpoint tests
   b. Data validation tests
   c. Integration flow tests

3. Verify results:

   • Check response formats
   • Validate error handling
   • Confirm data consistency

Notes

• Skip linting unless required
• Avoid deno task check
• Focus on manual code review
• Document failing tests separately

Dependencies

• Requires Phase 1 (Utility Tests) for shared utilities
• Requires test database configuration
• May require mock services for external APIs

Detailed Test Flow for End-to-End Tests

Test Flow Structure

1. User Flow Tests

// File: /tests/e2e/flows/stampViewing.test.ts

import { assertEquals } from '@std/assert';
import { setupTestBrowser } from '../../utils/testSetup.ts';

Deno.test('Stamp Viewing Flow', async (t) => {
  // Test Group 1: Navigation
  await t.step('navigates to stamp details', async () => {
    const browser = await setupTestBrowser();
    await browser.navigate('/stamps/123');
    assertEquals(await browser.title(), 'Stamp Details | BTCStamps');
  });

  // Test Group 2: Mobile View
  await t.step('displays correctly on mobile', async () => {
    const browser = await setupTestBrowser({ viewport: 'mobile' });
    // Test mobile layout
  });

  // Test Group 3: Error States
  await t.step('handles invalid stamp ids', async () => {
    // Test error handling
  });
});

2. Data Integration Tests

// File: /tests/e2e/integration/dataFlow.test.ts

Deno.test('Data Integration Flow', async (t) => {
  // Test Group 1: Data Loading
  await t.step('loads and displays data correctly', async () => {
    // Test data flow
  });

  // Test Group 2: Cache Behavior
  await t.step('uses cache effectively', async () => {
    // Test caching
  });

  // Test Group 3: Updates
  await t.step('handles real-time updates', async () => {

  // Test Group 1: Desktop
  await t.step('works on desktop viewports', async () => {
    // Test desktop layout

   • Confirm responsive behavior

Notes

• Focus on real user scenarios
• Skip linting unless required
• Avoid deno task check
