DevOps / Maven Surefire Plugin Interview Questions

How do you pass system properties into your tests through Surefire?

 
<configuration>
  <systemPropertyVariables>
    <env>staging</env>
    <config.path>/etc/app/config.yml</config.path>
  </systemPropertyVariables>
</configuration>

Values set here appear as normal System.getProperty(...) calls inside the test JVM, letting you switch test behavior per environment without editing test code.

How do tests read values set via systemPropertyVariables?
