Integrating Tokens into Automated Testing

Introduction

Design tokens are a crucial aspect of modern design systems, providing a way to standardize visual properties. Integrating these tokens into automated testing ensures consistency and quality in UI components across different platforms.

Key Concepts

Step-by-Step Process

Integrating tokens into automated testing involves several steps:

1. Identify design tokens within your design system.
2. Set up your testing framework (e.g., Jest, Mocha).
3. Write tests that reference the design tokens.
4. Run the tests and validate the UI.
5. Refactor tokens and tests as necessary for improvements.

Example Code

const theme = {
    colors: {
        primary: '#007bff',
        secondary: '#6c757d',
    },
    spacing: {
        small: '8px',
        medium: '16px',
        large: '24px',
    },
};

test('button has primary color', () => {
    const button = render();
    expect(button).toHaveStyle(`background-color: ${theme.colors.primary}`);
});
            

Best Practices

• Keep design tokens centralized for easy access.
• Write reusable test functions that can apply to multiple components.
• Ensure your tokens reflect changes in design promptly.
• Utilize visual regression testing tools to catch UI changes.
