Efficiency Matters: Mastering Dockerized Scalable Grid for UI Tests
summary
Claims a working setup that runs Playwright running on Selenium Grid using Docker nodes and reuses existing Selenium infrastructure, with code and demo repos on GitHub. It parallelizes tests via containerized nodes, uses APIs or DB snapshots to create isolated per-test data, and favors atomic test design to enable concurrency. Reported scale includes 12,000 tests in 40 minutes across ~60 parallel runs on self-hosted machines, and the architecture supports mixed Selenium and Playwright jobs on the same grid.
