A Linux administrator execute the following steps in this order: 1. Changes some software code 2. Commits the changes to the Git repository 3. Triggers a job to compile 4. Execute some test scripts…

Build automation primarily covers compiling and packaging, but the described process also explicitly includes automated testing, which is a distinct and crucial part of the overall orchestration that 'Build automation' alone does not fully encompass.

Deployment automation refers to automatically deploying software to target environments, which typically occurs after the package has been built, tested, and published to a repository, as described in step 6.

The administrator's workflow involves making code changes, committing them to Git, then triggering an automated job that compiles the code, executes test scripts, packages the software, and publishes it. The execution of test scripts (step 4) is a core component of this process, directly corresponding to test automation, which is critical for ensuring code quality and is a fundamental part of Continuous Integration.

Infrastructure automation focuses on provisioning and managing the underlying infrastructure, not the specific stages of software build, test, and release cycles described here.
