Selenium Cloud Computing & Services 5

Question 1

Which AWS service can trigger a Selenium test suite automatically whenever new code is pushed to a repository?

Accepted Answer

AWS CodePipeline

Answer

AWS CodePipeline orchestrates CI/CD workflows and can invoke build and test stages—including running Selenium tests—on every code commit.

Question 2

What is the key difference between 'stateless' and 'stateful' Selenium Grid nodes in a cloud environment?

Accepted Answer

Stateless nodes are destroyed after each session; stateful nodes persist and may carry leftover browser state

Answer

Stateless nodes are recycled after each session ensuring a clean environment, while stateful nodes persist and risk test pollution from prior sessions.

Question 3

In cloud Selenium testing, what is a 'desired capabilities' object used for when initiating a remote session?

Accepted Answer

Specifying browser type, version, OS, and other session requirements to the Grid

Answer

Desired capabilities (or W3C options) tell the Grid which browser, version, platform, and feature flags the test requires so it can route to a matching node.

Question 4

Which Selenium Grid 4 component is responsible for maintaining the mapping between active session IDs and the nodes that own them?

Accepted Answer

Session Map

Answer

The Session Map stores the active session-to-node associations so subsequent WebDriver commands are forwarded to the correct node.

Question 5

When cloud Selenium tests produce flaky results due to variable network latency, which WebDriver setting should be tuned first?

Accepted Answer

Implicit or explicit wait timeouts

Answer

Increasing explicit or implicit waits gives elements more time to appear under slower network conditions, directly addressing latency-driven flakiness.
