Quality Assurance
Test Validation

Test Validation

React Kickstart's QA automation includes comprehensive test validation to ensure that generated projects not only build correctly but also have passing, meaningful tests that validate the application functionality.

Quality Assurance: Test validation goes beyond build verification to ensure generated tests actually work and provide value to developers.

🎯 Validation Scope

The test validation system ensures multiple layers of quality:

✅ What Gets Validated

Build Validation

  • Project builds successfully (npm run build)
  • No compilation errors or warnings
  • All dependencies resolve correctly
  • TypeScript compilation (when enabled)

Test Validation 🆕

  • Test scripts execute without errors
  • All generated tests pass
  • Test frameworks work correctly (Jest/Vitest)
  • State management integration tests
  • Component rendering tests
  • API integration tests (when applicable)

Framework Integration

  • Font mocking works for Next.js projects
  • Module resolution works correctly
  • Asset handling in test environment
  • Environment configuration is proper

Linting Validation

  • ESLint configuration works (when enabled)
  • Code follows style guidelines
  • No linting errors in generated code

🧪 Test Categories

Component Unit Tests:

// Example generated test for Counter component
import { render, screen, fireEvent } from '@testing-library/react'
import Counter from '../Counter'
 
describe('Counter Component', () => {
  it('renders with initial count of 0', () => {
    render(<Counter />)
    expect(screen.getByText('Count: 0')).toBeInTheDocument()
  })
  
  it('increments count when increment button is clicked', () => {
    render(<Counter />)
    const incrementButton = screen.getByText('+')
    fireEvent.click(incrementButton)
    expect(screen.getByText('Count: 1')).toBeInTheDocument()
  })
  
  it('decrements count when decrement button is clicked', () => {
    render(<Counter />)
    const decrementButton = screen.getByText('-')
    fireEvent.click(decrementButton)
    expect(screen.getByText('Count: -1')).toBeInTheDocument()
  })
})

Validation Checks:

  • ✅ Tests render components without errors
  • ✅ User interactions work correctly
  • ✅ Component state updates properly
  • ✅ Props are handled correctly

🔍 Validation Process

Project Generation

Generate test project with specific configuration:

# Example: Generate Vite + TypeScript + Redux + Tailwind project
node bin/react-kickstart.js qa-test-project --yes \
  --framework vite \
  --typescript \
  --state redux \
  --styling tailwind \
  --testing vitest

Dependency Installation

Install all project dependencies:

cd qa-test-project
npm install

Test Execution

Run the complete test suite:

# Run all tests
npm run test
 
# Run tests with coverage
npm run test:coverage
 
# Run linting (if enabled)
npm run lint

Result Analysis

Analyze test results and generate validation report:

// Test validation analysis
const testResults = {
  framework: 'vite',
  testRunner: 'vitest',
  totalTests: 12,
  passingTests: 12,
  failingTests: 0,
  coverage: {
    statements: 95.2,
    branches: 89.1,
    functions: 100,
    lines: 94.8
  },
  performance: {
    testDuration: 2.3,
    slowestTest: 'API integration test (450ms)'
  }
}

Quality Metrics

Evaluate against quality thresholds:

const qualityThresholds = {
  testPassRate: 100,        // All tests must pass
  minCoverage: 80,          // Minimum 80% coverage
  maxTestDuration: 30,      // Tests should complete in 30s
  maxSlowTest: 2000,        // No single test > 2s
  lintingErrors: 0          // Zero linting errors
}

Common Test Issues

⚠️

Test Environment: Many test failures are due to environment configuration issues rather than actual code problems.

Dependency Issues:

{
  "issue": "Missing test dependencies",
  "description": "@testing-library/jest-dom not configured",
  "solution": "Add to test setup file",
  "impact": "Assertions fail unexpectedly"
}

Configuration Issues:

{
  "issue": "Jest/Vitest configuration conflict",
  "description": "Transform configuration incorrect",
  "solution": "Update test configuration for framework",
  "impact": "Tests fail to run"
}

Mocking Issues:

{
  "issue": "Next.js font mocking missing",
  "description": "next/font/google not mocked",
  "solution": "Add font mocking to test setup",
  "impact": "Next.js tests fail"
}

🛠️ Test Generation Strategy

Automatic Test Generation

React Kickstart generates meaningful tests based on the selected features:

Generated Component Tests:

// Auto-generated based on components created
describe('App Component', () => {
  it('renders welcome message', () => {
    render(<App />)
    expect(screen.getByText(/welcome to react kickstart/i)).toBeInTheDocument()
  })
  
  it('renders navigation when routing enabled', () => {
    render(<App />)
    expect(screen.getByRole('navigation')).toBeInTheDocument()
  })
  
  it('applies correct styling classes', () => {
    render(<App />)
    const container = screen.getByTestId('app-container')
    expect(container).toHaveClass('min-h-screen', 'bg-gray-100')
  })
})

Test Quality Standards

Generated tests must meet these criteria:

  • ✅ Meaningful Assertions - Tests verify actual functionality
  • ✅ Proper Setup/Teardown - Clean test environment
  • ✅ Error Scenarios - Test both success and failure cases
  • ✅ Performance Aware - Tests complete quickly
  • ✅ Maintainable - Clear, readable test code
  • ✅ Framework Appropriate - Use correct testing patterns
