DevOps / Maven Surefire Plugin Interview Questions

How do you run only tests with a specific JUnit 5 tag or TestNG group?

Use <groups> and <excludedGroups>:

<configuration>
  <groups>fast</groups>
  <excludedGroups>slow</excludedGroups>
</configuration>

This maps to JUnit 5's @Tag annotation, or to TestNG's groups attribute when TestNG is the underlying framework.
