Web Platform Tests
Web Platform Tests (WPT) is a cross-browser test suite for web platform standards, including HTML, CSS, JavaScript APIs, and other web technologies. It provides a comprehensive set of automated tests to ensure interoperability and compliance with specifications across different browsers and implementations. The project is community-driven and serves as a key tool for web standards development and browser testing.
Developers should learn and use Web Platform Tests when working on web standards compliance, browser development, or cross-browser compatibility testing to identify and fix implementation bugs. It is essential for ensuring that web features work consistently across platforms, such as when building polyfills, contributing to browser engines, or validating new web APIs. Use cases include automated regression testing, specification conformance checks, and interoperability validation in CI/CD pipelines.
