Phase 2: Component Tests Implementation

[devin-ai-integration]

Component Tests Implementation Plan

Parent issue: #517

Overview

This issue tracks the implementation of component tests, focusing on UI Components and Interactive Islands.

Test Scope

UI Components

Location: /components/
Test coverage needed for:

• Server-side rendered components
• Mobile responsiveness
• Error state handling

Interactive Islands

Location: /islands/
Test coverage needed for:

• BlockInfo.tsx component
• Client-side interactions
• State management
• Event handlers

Test Cases to Implement

1. Server-Side Components

• Test initial render states
• Test prop validation
• Test error boundaries
• Test mobile responsive classes

2. Interactive Islands

• Test BlockInfo.tsx loading states
• Test user interactions
• Test state updates
• Test error handling
• Test mobile responsive behavior

3. Mobile Responsiveness

• Test breakpoint behavior
• Test text size responsiveness
• Test spacing and padding
• Test component-specific styling

Implementation Guidelines

1. Follow Deno Fresh component patterns
2. Use Tailwind CSS for styling tests
3. Focus on manual code review
4. Test mobile-first approach

Test File Structure

// Example test structure for /tests/components/BlockInfo.test.ts

import { assertEquals } from '@std/assert';
import { BlockInfo } from '../../islands/BlockInfo.tsx';

Deno.test('BlockInfo Component', async (t) => {
  await t.step('renders in loading state', () => {
    // Test implementation
  });

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

Success Criteria

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

Dependencies

• Requires completion of Phase 1 (Utility Tests)

Detailed Test Flow for Utility Tests

Test Flow Structure

1. Binary Data Conversion Tests

// File: /tests/utils/binary/baseUtils.test.ts

import { assertEquals } from '@std/assert';
import { convertToBinary, convertFromBinary } from '../../../lib/utils/binary/baseUtils.ts';

Deno.test('Binary Conversion Utils', async (t) => {
  // Test Group 1: Basic Conversion
  await t.step('converts string to binary and back', () => {
    const testData = 'Hello World';
    const binary = convertToBinary(testData);
    const result = convertFromBinary(binary);
    assertEquals(result, testData);
  });

  // Test Group 2: Edge Cases
  await t.step('handles empty input', () => {
    const testData = '';
    const binary = convertToBinary(testData);
    const result = convertFromBinary(binary);
    assertEquals(result, testData);
  });

  // Test Group 3: Error Cases
  await t.step('throws on invalid input', () => {
    try {
      convertToBinary(null);
      throw new Error('Should have thrown');
    } catch (e) {
      assertEquals(e.message, 'Invalid input');
    }
  });
});

2. Type Validation Tests

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

Deno.test('Type Validation Utils', async (t) => {
  // Test Group 1: Type Checking
  await t.step('validates string types', () => {
    // Implementation
  });

  // Test Group 2: Format Validation
  await t.step('validates hex format', () => {
    // Implementation
  });
});

3. Error Handling Tests

// File: /tests/utils/errors.test.ts

Deno.test('Error Handling Utils', async (t) => {
  // Test Group 1: Error Generation
  await t.step('generates correct error types', () => {
    // Implementation
  });

  // Test Group 2: Error Recovery
  await t.step('recovers from known errors', () => {
    // Implementation
  });
});

Test Execution Flow

1. Setup test environment

   • Import required utilities
   • Prepare test data
   • Configure test context

2. Run test suites in order:
   a. Binary conversion tests
   b. Type validation tests
   c. Error handling tests

3. Verify results:

   • Check test coverage
   • Validate error cases
   • Confirm edge case handling

Notes

• Tests can be run individually using deno test <file>
• Skip linting unless specifically required
• Focus on manual code review
• Document any failing tests separately

Dependencies

None - These are foundational utility tests
