This document discusses using Docker to run Geb tests with real browsers. It provides instructions on installing Docker images, configuring Geb to use a Dockerized browser via RemoteWebDriver, and running Gradle tests within a Docker container to test a web application using the Dockerized browser. Viewing the browser session within Docker is also demonstrated using VNC. Migrating CI/testing to use Dockerized browsers is mentioned as a way to ensure tests use real browsers.
