Creating Test Suite with TestNG

What is a Test Suite?

A Test Suite groups multiple test classes together, configured through testng.xml, and run as a single execution.

Example

<suite name="Regression Suite">
  <test name="Login Tests">
    <classes>
      <class name="tests.LoginTest"/>
      <class name="tests.LogoutTest"/>
    </classes>
  </test>
</suite>

Why This Matters

Suites let a team run a full regression pack, or a smaller smoke-test subset, with a single command — useful both locally and in a CI/CD pipeline like Jenkins.
