Test Space Nodejs

What is Test Space Nodejs ?

Test Space Nodejs is a lightweight Node.js module designed to assist in visual testing and comparisons. It enables developers to compare visual elements in screenshots to detect regressions and maintain consistency in UI/UX designs. This tool is particularly useful for front-end development and testing workflows, allowing teams to automate visual validations and ensure pixel-perfect results.

Features

• Cross-platform compatibility: Works on multiple operating systems, including Windows, macOS, and Linux.
• Visual comparison: Performs pixel-level comparisons between baseline images and new screenshots.
• Integration with testing frameworks: Easily integrates with popular Node.js testing frameworks like Jest and Mocha.
• Real-time feedback: Provides immediate results on visual mismatches, enabling quick debugging.
• Customizable settings: Allows users to adjust sensitivity levels for comparison and ignore specific regions.

How to use Test Space Nodejs ?

1. Install the package: Run npm install test-space-nodejs to add it to your project.
2. Import in your test file: Use const testSpace = require('test-space-nodejs'); to include the module.
3. Set up baseline images: Capture and store reference screenshots for comparison.
4. Write test assertions: Use testSpace.compare() to check if new screenshots match the baseline images.
5. Handle results: Use callbacks or promises to handle comparison results and update baselines as needed.
