Parameterization annotation with testing.xml

Parameterization with TestNG:-

 When we want to run the any test cases with different set of test data then we need to use parameterization.TestNG provides two ways to do parameterization in our test scripts.

1.    By using Parameters annotation and testing.xml

2.    By using DataProvider annotation           

     

 Parameterization annotation with testing.xml :-

 Now take a scenario so that we can better understand:

•      Open - https://www.freecrm.com/index.html
•      Login with valid username and password

 Now in this case we will pass the parameters value of username and password in       testing.xml file.

1.First we will write the code for opening given above URL and then login –

package seleniumPkg;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

import org.testng.annotations.Parameters;

import org.testng.annotations.Test;

public class ParamterizationTestNG {

            WebDriver driver;

            @Test()

            @Parameters({ "browser", "username", "password" })

            public void openBrowser(String br, String usernm, String pwd) throws InterruptedException {

                        if (br.equals("chrome")) {

                                    System.setProperty("webdriver.chrome.driver", "D:\\Selenium Jars\\chromedriver_win32\\chromedriver.exe");

                                    driver = new ChromeDriver();

                                    driver.get("https://freecrm.com/index.html");

                                    driver.manage().window().maximize();

                                    driver.manage().deleteAllCookies();

                                    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

                                    driver.findElement(By.name("username")).sendKeys(usernm);

                                    driver.findElement(By.name("password")).sendKeys(pwd);

                                    driver.findElement(By.xpath("//input[@type='submit']")).click();

                                    Thread.sleep(5000);

                                    driver.quit();

                        }

                        else if (br.equals("FF")) {

                                    System.out.println("open firefox browser");

                        }

            }

}

Note:- You can see above after @Test annotation we have added @Parameters and also passed browser, username and password because I want to make these should be parameterized.

2. Now we will pass value of browser, username and password from testing.xml file

Code:

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

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

<suite name="Suite">

  <test name="Test">

   <parameter name="browser" value="chrome"/>

  <parameter name="username" value="naveenk"/>

  <parameter name="password" value="test@123"/>

    <classes>

      <class name="seleniumPkg.ParamterizationTestNG"/>

    </classes>

  </test> <!-- Test -->

</suite> <!-- Suite -->

Internally passed values like below :-

Note:- You can see here at a time we can only give one value to the parameter because this not possible with @parameters annotation to pass multiple values so if we want to pass different set of values to the parameters then we have to use Data Provider annotation.

Now run the test script by right clicking on testing.xml file. In coming tutorial we will see parameterization with DataProvider.
