This project serves as both a reference implementation and a learning resource for writing effective tests in Next.js applications.\n\n## Features\nThis project demonstrates testing best practices for:\n\n- Unit testing with Jest\n- Component testing with React Testing Library\n- Form validation and user input handling\n- Async operations and API mocking\n- Custom test utilities and helpers\n- TypeScript integration\n- Test coverage reporting\n\n- \n## Getting Started\nPrerequisites\nBefore you begin, ensure you have the following installed:\n\n- Node.js (version 14 or higher)\n- npm (version 6 or higher)\n- Git\n\n1.Clone the repository:\n```bash\n git clone [https://github.com/yourusername/testing-nextjs.git](https://github.com/Amir1887/Next.js-Unit-Test-.git)\ncd testing-nextjs\n```\n\n2.Install dependencies:\n```bash\nnpm install\n```\n3.Run the development server:\n```bash\nnpm run dev\n```\n4.Open http://localhost:3000 in your browser to see the application.\n\n## Testing\n## Running Tests\nThis project includes several testing scripts:\n- Run all tests:\n```bash\nnpm test\n```\n- Run tests in watch mode (recommended during development):\n ```bash\n  npm run test:watch\n```\n-Generate test coverage report:\n```bash\nnpm run test:coverage\n```\n## Test Structure\n__tests__/\n├── setup.ts                 # Global test configuration\n├── components/             \n│   ├── Counter.test.tsx    # Component tests\n│   └── UserForm.test.tsx\n└── utils/\n    └── calculator.test.ts  # Utility function tests\n\n## Testing Utilities\nThe project includes several testing utilities and helpers:\n\n## 1.Custom Matchers\n\n- toBeWithinRange: Check if a number is within a specified range\n- toBeValidEmail: Validate email format\n    ```bash\n  expect(user.age).toBeWithinRange(18, 65)\n  expect(user.email).toBeValidEmail()\n  ```\n## 2.Mock Data Factories\n\n- createMockUser: Generate test user data\n- createMockPost: Generate test post data\n   ```bash\n     const testUser = createMockUser({ age: 25 })\n     const testPost = createMockPost({ authorId: testUser.id })\n  ```\n## Project Structure\n├── components/             # React components\n│   ├── Counter.tsx\n│   └── UserForm.tsx\n├── utils/                 # Utility functions\n│   └── calculator.ts\n├── __tests__/            # Test files\n├── jest.config.js        # Jest configuration\n└── tsconfig.json         # TypeScript configuration\n\n\n## Key Components\n## Counter Component\nA simple counter component demonstrating state management and event handling:\n```bash\n    import { Counter } from '@/components/Counter'\n  \n  // Example usage\n  \u003cCounter initialValue={0} /\u003e\n```\n## UserForm Component\nA form component showcasing input handling and validation:\n```bash\n    import { UserForm } from '@/components/UserForm'\n  \n  // Example usage\n  \u003cUserForm onSubmit={handleSubmit} /\u003e\n```\n\n## Best Practices Demonstrated\n\n## 1.Component Testing\n\n- Rendering components\n- User interaction simulation\n- State changes verification\n- Form submission handling\n\n\n## 2.Utility Testing\n\n- Pure function testing\n- Error handling\n- Edge cases\n\n\n## 3.Mock Usage\n\n- API call mocking\n- Browser API simulation\n- Event handling\n\n\n\n## 4.Environment Setup\nThe project includes comprehensive environment setup for testing:\n\n## 1.Browser API Mocks\n\n- ResizeObserver\n- window.matchMedia\n- TextEncoder/TextDecoder\n\n\n## 2.Error Handling\n\n- Custom error classes\n- Unhandled promise rejection handling\n- Console error filtering\n\n\n\n## Contributing\n\n- Fork the repository\n- Create your feature branch (git checkout -b feature/AmazingFeature)\n- Commit your changes (git commit -m 'Add some AmazingFeature')\n- Push to the branch (git push origin feature/AmazingFeature)\n- Open a Pull Request\n\n## License\nThis project is licensed under the MIT License - see the LICENSE.md file for details\n\n## Acknowledgments\n\n- Next.js team for the fantastic framework\n- Jest team for the testing framework\n- Testing Library team for the excellent testing utilities\n- The open source community for continuous inspiration\n\n## Contact\nAmir Adel - @Amir1887\nProject Link: [https://github.com/yourusername/testing-nextjs](https://github.com/Amir1887/Next.js-Unit-Test-)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famir1887%2Fnext.js-unit-test-","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Famir1887%2Fnext.js-unit-test-","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famir1887%2Fnext.js-unit-test-/lists"}
