The **Onslip Automation** library is a Node‑js toolkit that lets developers remotely control and end‑to‑end test Android and iOS WebViews—including legacy WebViews used by Capacitor or Cordova hybrid apps—through a Playwright‑style API. It is aimed at mobile developers and QA engineers who need to automate or test hybrid applications on real devices or emulators, even on very old WebView versions that Playwright itself does not support.
