Grid 4 has the ability to start Docker containers on-demand, this means that it starts a Docker container in the background for each new session request, the test gets executed there, and when the test completes, the container gets thrown away. This execution mode can be used either in the Standalone or Node roles. The "dynamic" execution mode needs to be told what Docker images to use when the containers get started. Additionally, the Grid needs to know the URI of the Docker daemon. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point, making it easy to run the tests against a vast combination of browsers/OS, then you want to use Selenium Grid. It is possible to start a Selenium Grid with all its components apart. For simplicity, only an example with docker-compose will be provided. Save the file locally, and check the execution instructions on top of it.
Features
- Docker images for Grid 4 come with a handful of tags to simplify its usage
- To get notifications of new releases, add yourself as a "Releases only" watcher
- All the contact points for the different Selenium projects can be seen at support
- Only one Standalone container can run on port 4444 at the same time
- There are different ways to run the images and create a Grid with a Hub and Nodes
- The Hub and Nodes will be created in the same network and they will recognize each other by their container name
