TestNG Parametrization: Part-1

Parametrization means passing values in Unit test script using TestNG xml file, or using @DataProvider testing annotation

Parametrization using testing xml file:

For this type of parametrization need to declare “@Parameters” annotation in method which needs parameter testing, the value of parameter will be provided by using TestNG suite xml file. Using this we can Test a single unit test for multiple set of values.
Example – we need to create java test file as I created MyTestNG.java file.

package com.test;

import org.testng.annotations.AfterClass;

import org.testng.annotations.BeforeClass;

import org.testng.annotations.Parameters;

import org.testng.annotations.Test;

public class MyTestNG {       

           

        @BeforeClass

        public void beforeClass() {

            System.out.println("@BeforeClass - executed");

        }

         

        @AfterClass

        public void afterClass() {

            System.out.println("@AfterClass - executed");

         }     

                

        @Test

        @Parameters({"fName", "lName"})

        public void testParameterMethod(String fName, String lName) 
        {       

           System.out.println(fName);

           System.out.println(lName);

        }

}

Suite.xml file.

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

<suite name="TestNG Suite">

  <test name="method">

    <parameter name="fName" value="First Name"/>

    <parameter name="lName" value="Last Name"/>

    <classes>

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

    </classes>

  </test>

</suite>

Output:
 

@BeforeClass - executed

First Name

Last Name

@AfterClass - executed
