Groups in TestNG

Groups in TestNG:-

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

Example 1st:-

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");

  }

}

testng.xml

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Suite">

    <test name="Practice Grouping">

      <groups>

       <run>

          <include name="B" />

       </run>

      </groups>

      <classes>

        <class name="scs.NewTest" />

      </classes>

    </test>

</suite>

Another Example:-

package scs;

import org.testng.annotations.AfterGroups;

import org.testng.annotations.BeforeGroups;

import org.testng.annotations.BeforeTest;

import org.testng.annotations.Test;

public class EroomRentTestCase {

@BeforeTest

public void fun()

{

System.out.println("Before Test");

}

@BeforeGroups("guest")

public void beforeGuestGroup()

{

    System.out.println("Before Guest Group");

}

@BeforeGroups("owner")

public void beforeOwnerGroup()

{

    System.out.println("Before Owner Group");

}

@Test(groups={"guest"})

public void guestTestCaseMethod()

{

    System.out.println("Guest Modules");

}

@Test(groups={"owner"})

public void OwnerTestCaseMethod()

{

System.out.println("Owner Modules");

}

@Test(groups={"guest","owner"})

public void TenantTestCaseMethod()

{

System.out.println("Tenant Modules");

}

@AfterGroups("guest")

public void AfterGuestGroup()

{

    System.out.println("After Guest Group");

}

@AfterGroups("owner")

public void afterOwnerGroup()

{

    System.out.println("After Owner Group");

}

}

create XML file to execute a single group:-

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Suite">

    <test name="Practice Grouping">

      <groups>

       <run>

          <include name="guest" />

       </run>

      </groups>

      <classes>

        <class name="scs.EroomRentTestCase" />

      </classes>

    </test>

</suite>

Create XML file to execute Multiple Group:-

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Suite">

<test name="Practice Grouping">

<groups>

<define name="All">

<include name="guest"/>

<include name="owner"/>

</define>

<run>

<include name="All"/>

</run>

</groups>

<classes>

<class name="scs.EroomRentTestCase" />

</classes>

</test>

</suite>
