Running TestNG Suite File Using Surefire Plugin

How It Works

Once the Surefire Plugin is configured with a reference to testng.xml, running mvn test from the command line (or Eclipse) automatically triggers TestNG to execute exactly the suite defined in that XML file.

Why This Is Powerful

This is the exact mechanism CI/CD tools like Jenkins use — triggering mvn test after every code change automatically runs the full TestNG suite and reports pass/fail results.
