What is the main purpose of unit tests in software development?

• Test the entire software system

• Verify individual functions or methods

• Run integration tests

• Replace manual testing entirely

In a GitLab CI pipeline configuration, how can you run multiple jobs concurrently?

• Define multiple scripts in one job

• Place the jobs in the same pipeline stage

• Assign different runners to each job

• Use a separate .parallel stage

Why are unit tests placed at the bottom of the testing pyramid?

• They are the slowest to run

• They are least important

• They test system-wide integrations

• They are fast, numerous, and provide quick feedback

Why is parallel job execution beneficial in GitLab pipelines?

• It speeds up the pipeline by running multiple jobs simultaneously

• It simplifies debugging

• It merges jobs into one large job

• It reduces the total number of jobs

What happens if you remove the stages configuration from a GitLab pipeline?

• The pipeline automatically stops working

• GitLab applies default stages (.pre, build, test, deploy, .post)

• Jobs run randomly

• The pipeline fails

What is a JUnit report in a CI pipeline?

• A console-only output

• A detailed XML test results file

• A performance monitoring tool

• A manual testing guide

What does the following artifact configuration achieve in a GitLab CI job?

• Generates a JUnit test report

• Publishes artifacts only if the job passes

• Publishes the artifact regardless of job success or failure

• Publishes a JUnit test report
