Question 1

How to set up Zalenium with Docker for local testing?

Accepted Answer

Pull the elgalu/selenium and dosel/zalenium Docker images, then run a command with volume mounts for videos and Docker.sock access. The README provides a one-line installer script for OSX/Linux to simplify this process.

Question 2

Is Zalenium better than standard Selenium Grid for CI/CD pipelines?

Accepted Answer

Zalenium offers dynamic scaling and cloud integration for faster, more flexible testing, but since it's deprecated, Selenium Grid 4.x is now a better choice for long-term CI/CD stability and active development.

Question 3

Does Zalenium support Safari or Edge browsers locally?

Accepted Answer

No, Zalenium only supports Chrome and Firefox locally. For Safari, Edge, or other browsers, tests are automatically redirected to cloud providers like Sauce Labs, which may require additional accounts and fees.

Question 4

How do I record and access test videos in Zalenium?

Accepted Answer

Videos are recorded automatically and stored in a mapped directory (e.g., /tmp/videos). You can view them via the centralized dashboard or customize file naming through capabilities, as detailed in the documentation.

Question 5

Is Zalenium still maintained or should I migrate away?

Accepted Answer

Zalenium is no longer maintained; the project recommends migrating to Selenium Grid 4.x, which is implementing similar features upstream. For new projects, consider alternatives like docker-selenium or cloud-based grids.

Question 6

Can I use Zalenium without Kubernetes or in simple setups?

Accepted Answer

Yes, Zalenium works with basic Docker environments, but its dynamic scaling and Kubernetes support add overhead that might be unnecessary for simple, static grid setups where a standard Selenium Grid suffices.
