Groups in TestNG

Groups in TestNG:-

It is used to logically subdivided the test case method, based on their usability.  to create a group, tesng provides "groups" attribute, and "beforegroups" and "aftergroups" annotation will be called for each grouping method.

package scs;

import org.testng.annotations.*;

public class TestNGExampleNew {

@BeforeGroups("car")

    public void bg1()

    {

           System.out.println("Car1");

    }

    @AfterGroups("car")

    public void bg2()

    {

    System.out.println("Car2");

    }

   @Test(groups={"car"})

   public void car1()

   {

   System.out.println("Car3");

   }

  @Test(groups={"car"})

   public void car2()

   {

  System.out.println("Car4");

   }

  @Test(groups={"scooter"})

   public void scooter1()

   {

  System.out.println("Scooter1");

   }

  @Test(groups={"scooter"})

   public void scooter2()

   {

  System.out.println("Scooter2");

   }

  @Test(groups={"scooter","car"})

  public void car_scooter()

 {

  System.out.println("Car, Scooter");

 }

}

create testng.xml file and execute them

<suite name="Suite">

    <test name="Practice Grouping">
      <groups>
       <run>
          <include name="Car" />
       </run>
      </groups>
      <classes>
        <class name="packagename.Classname" />
      </classes>
    </test>

</suite>


To run multiple groups

<suite name="Suite">

   <test name="Practice Grouping">

      <groups>

         <define name="All">

    <include name="Car"/>

    <include name="Scooter"/>

</define>

<run>

    <include name="All"/>

</run>

    </groups>

<classes>

      <class name="package.Grouping" />

</classes>

   </test>

</suite>

Example of Groups

package scs;

import org.testng.annotations.Test;

import org.testng.annotations.BeforeTest;

import org.testng.annotations.AfterGroups;

import org.testng.annotations.AfterTest;

import org.testng.annotations.BeforeGroups;

public class NewTest {

 

  @Test(groups={"A"})

  public void testcase1() {

  System.out.print("TEST CASE CODE 1");

  }

  

  @Test(groups={"A"})

  public void testCase2() {

  System.out.print("TEST CASE CODE 2");

  }

  @Test(groups={"B"})

  public void testCase3() {

  System.out.print("TEST CASE CODE 3");

  }

  @BeforeTest

  public void beforeTest() {

  System.out.print("BEFORE TEST CASE CODE");

  }

  @AfterTest

  public void afterTest() {

  System.out.print("AFTER TEST CASE CODE");

  }

  @BeforeGroups

  public void beforeGroup() {

  System.out.print("BEFORE GROUP CODE");

  }

  @AfterGroups

  public void afterGroup() {

  System.out.print("AFTER GROUP CODE");

  }

}
