Selenium Testing Framework Selenium CI/CD Integration & Automation Architecture

Question 1

Which Maven plugin is commonly used to run Selenium/TestNG tests as part of a CI build?

Accepted Answer

maven-surefire-plugin

Answer

The maven-surefire-plugin executes unit and integration test classes during the `test` lifecycle phase in a Maven build.

Question 2

In a Jenkins pipeline, which stage would you typically run Selenium regression tests?

Accepted Answer

Post-deploy test stage after the application is deployed to a test environment

Answer

Selenium tests need a running application to interact with, so they are executed after the app is deployed to a test environment.

Question 3

What is the purpose of using headless browser mode (e.g., `--headless` flag) in CI/CD pipelines?

Accepted Answer

To run browser tests on servers without a display or GUI

Answer

Headless mode allows Chrome or Firefox to run without a graphical display, making Selenium tests possible on CI servers with no screen.

Question 4

Which GitHub Actions feature allows you to run Selenium tests against a browser installed on the runner?

Accepted Answer

Browser installed by default on ubuntu-latest runners

Answer

GitHub Actions ubuntu-latest runners come with Chrome and Firefox pre-installed, so Selenium tests can run directly without extra setup.

Question 5

What does 'shift-left testing' mean in the context of Selenium and CI/CD?

Accepted Answer

Running tests earlier in the development lifecycle, catching bugs before deployment

Answer

Shift-left testing integrates automated tests earlier in the pipeline so developers get fast feedback before code reaches production.
