Selenium Cloud Computing & Services 3

Question 1

Which Selenium Grid 4 component acts as the entry point that accepts new session requests and routes them to available nodes?

Accepted Answer

Router

Answer

The Router is the front-door component that receives WebDriver commands and delegates them to the appropriate internal Grid components.

Question 2

A cloud Selenium test suite needs to run against a staging site accessible only inside a VPC. Which approach best enables this?

Accepted Answer

Deploy the Selenium Grid nodes inside the same VPC as the staging site

Answer

Deploying Grid nodes inside the VPC gives them direct network access to internal staging URLs without exposing them to the internet.

Question 3

Which Google Cloud service is commonly used to run containerized Selenium Grid nodes as serverless jobs without managing VM infrastructure?

Accepted Answer

Google Cloud Run

Answer

Cloud Run executes containers on demand and scales to zero when idle, making it cost-efficient for running Selenium node containers.

Question 4

What Helm chart is officially provided by the Selenium project for deploying Selenium Grid on Kubernetes?

Accepted Answer

seleniumhq/selenium-grid

Answer

The official Helm chart is maintained at seleniumhq/selenium-grid and supports deploying Hub, Router, Distributor, and nodes on Kubernetes.

Question 5

In cloud-based parallel Selenium testing, what is the role of a 'session queue'?

Accepted Answer

Holds pending WebDriver session requests until a node becomes available

Answer

The session queue buffers incoming new-session requests so they are not dropped when all nodes are busy, ensuring orderly dispatch.
