Playwright Test is the runner for end-to-end (E2E) testing. It provides browser isolation, auto-waiting, web-first assertions, parallel execution, and tracing. Playwright CLI and Playwright MCP support browser automation for agents, and with Playwright Library you can write automation scripts without a test runner. The project is written in TypeScript and distributed under the Apache-2.0 license. The core is a setup that drives three browser engines with one API while offering both test execution and automation.
However, the provided information contains no change list or performance measurements for v1.64.1. Therefore, what this release improves over previous versions, and how effective it is in real environments, cannot be judged from this material alone. What can be confirmed is the range of testing and automation features across multiple browsers; version-by-version changes must be checked separately in the release notes.
