Become Black Ops QA with Selenium 4 BiDi-DevTools APIs
summary
Walks through concrete Selenium 4 usage: Chromium CDP and the newer WebDriver BiDi to simulate geolocation and time zones (data‑driven Java tests that set coordinates for world capitals and verify distances), pin reusable JavaScript for highlighting and toast messages via pinScript and highlight, capture JS exceptions and DOM mutations, intercept and mock HTTP (useful to reproduce flaky third‑party payments), implement a black‑hole proxy with network.setBlockedURLs, run on remote grids after calling augmenter; found a memory leak in an SPA and shows metrics to detect it.
