How to create TestNG suite file.

TestNG suite means grouping two or more than two classes to execute with a single command.

How to create:

Create some test class as I created below two test class  “FirstTest.java” and “SecondTest.java” java files.

FirstTest.java:

import org.testng.annotations.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Test;

public class FirstTest {

       

        @BeforeClass

        public void beforeClass() {           

           System.out.println("One time executed before first mathod");

        }

         

        @AfterClass

        public void afterClass() {

            System.out.println("One time executed after last method");

        }

                  

        @Test

        public void testFirstMethod() {       

           System.out.println("@Test - executed first test method");

        }

}

SecondTest.java

import org.testng.annotations.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Test;

public class SecondTest {     

           

        @BeforeClass

        public void beforeClass() {   

                System.out.println("one time executed before first mathod");

        }

         

        @AfterClass

        public void afterClass() {    

                System.out.println("one time executed after last method");

         }     

         

        @Test

        public void testSecondMethod() {       

           System.out.println("@Test - executed second test method");

        }

}

Suite.xml file is suite file of above classes:

 

<!DOCTYPE suite SYSTEM "http://beust.com/testng/testng-1.0.dtd" >

<suite name="TestNG Suite">

  <test name="method">

    <classes>

       <class name="com.test.FirstTest" />

       <class name="com.test.SecondTest" />

    </classes>

  </test>

</suite>

Run this suite file using TestNG, both test classes should be executed.
