Have you ever struggled running selenium tests via Geb with webdriver-binaries due to driver version compatibility, configuration or a myriad of other complexity? Or only firefox/gecko works? Thanks to the hard work of @mattias_reichel and @sbglasius, all of that can be a thing of the past. For Grails 7, Geb 5.0.0-SNAPSHOT now provides a

ContainerGebSpec

class, which can be used in place of

GebSpec

, that automatically runs the browser in a container using Testcontainers. This only requires a compatible container runtime be installed, such as: • Docker Desktop • OrbStack - macOS only • Rancher Desktop • podman desktop • Colima - macOS and Linux You can preview this by cloning the 7.0.x branch on https://github.com/grails/grails-functional-tests.git, starting your container runtime and running

./gradlew build
