Advanced Component Testing in Modern UI Frameworks

Component Testing

Component testing is the process of testing individual components in isolation to ensure they function as expected. This can include unit tests, integration tests, and end-to-end tests.

Test-Driven Development (TDD)

TDD is a software development approach where tests are written before code. This ensures that code is written to fulfill the requirements specified in the tests.

Unit Testing

Unit testing focuses on testing individual components or functions in isolation. It ensures that each unit of the software performs as designed.

import { render, screen } from '@testing-library/react';
import MyComponent from './MyComponent';

test('renders MyComponent', () => {
    render();
    const linkElement = screen.getByText(/my component/i);
    expect(linkElement).toBeInTheDocument();
});

Integration Testing

Integration testing evaluates the interaction between multiple components or systems. This verifies that components work together as intended.

End-to-End Testing

End-to-end testing simulates real user scenarios to validate the entire application flow, ensuring all components function correctly in an environment resembling production.

Maintainability

• Write clear and concise tests.
• Group related tests together for better organization.
• Use descriptive names for test cases.

Performance

• Avoid unnecessary duplication in tests.
• Run tests in parallel when possible to speed up execution.
• Optimize the setup and teardown processes.

Continuous Integration

• Integrate testing into CI/CD pipelines.
• Run tests automatically on each commit or pull request.
• Monitor test results and address failures promptly.
