Grouping Test Cases in TestNG

In TestNG, grouping test cases allows you to organize and execute a specific subset of tests together. This is especially useful in large test suites where you may want to run only a particular category of tests (e.g., smoke tests, regression tests, or sanity tests).

How to Group Test Cases in TestNG

You can group test cases using the groups attribute of the @Test annotation.

Example: Grouping Test Cases

java

Copy

Edit

import org.testng.annotations.Test;

public class GroupTestExample {

    @Test(groups = {"smoke"})

    public void testLogin() {

        System.out.println("Smoke Test - Login Test");

    }

    @Test(groups = {"regression"})

    public void testAddToCart() {

        System.out.println("Regression Test - Add To Cart");

    }

    @Test(groups = {"smoke", "regression"})

    public void testSearchProduct() {

        System.out.println("Smoke & Regression Test - Search Product");

    }

}

Running Specific Groups in testng.xml

You can define which groups to include or exclude in your testng.xml file:

xml

Copy

Edit

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">

<suite name="MySuite">

  <test name="SmokeTests">

    <groups>

      <run>

        <include name="smoke"/>

      </run>

    </groups>

    <classes>

      <class name="GroupTestExample"/>

    </classes>

  </test>

</suite>

Using Groups with Annotations

You can also include/exclude groups programmatically or in Maven with the Surefire plugin, like:

xml

Copy

Edit

<groups>smoke</groups>

Or:

xml

Copy

Edit

<excludedGroups>regression</excludedGroups>

Benefits of Grouping Tests

Easier test management

Better control over test execution

Supports different testing needs (smoke, sanity, regression)

Saves time by avoiding unnecessary test runs
