Sample TestNG TestCase

In previous post we have seen introduction and setup for TestNG, in this post will focus on how to write a simple TestNG case. 

Step 1 – Write the business logic of the test

Step 2 – Insert TestNG annotations in the code

Step 3 – Add the information about your test (e.g. the class names, methods names, groups names etc…) in a testng.xml file

Step 4 – Run TestNG

Open eclipse and create a new Project as : TestNGSample

 under this project create a new Package as com.test

Right click on the com.test package and go to Other option and look got TestNG Class as shown

Enter FirstTest as name and click on Finish 

 You will see some error in the programming like this and

We need to add TestnNG library, mouse move to org.testng and add the necessary library

For FirstTest class file lets add annotations 

@BeforeMethod : Launch Firefox and direct it to the Base URL

@Test : Enter Username & Password to Login, Print console message and Log out

@AfterMethod : Close Firefox

Before copying this file make sure you add selenium jar to project class path

And also make sure to add all testng library from the script

Script :

package com.test;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class FirstTest {
    WebDriver driver; 
   
    @BeforeMethod
    public void Init(){
         driver=new FirefoxDriver();
    }
   
  @Test
  public void TestCase1() throws InterruptedException {
                 
      driver.get("http://opensource.demo.orangehrm.com/index.php/auth/login");
 
            Thread.sleep(7000);
            driver.manage().window().maximize();        

           driver.findElement(By.xpath("//*[@id='txtUsername']")).sendKeys("Admin");
            driver.findElement(By.xpath("//*[@id='txtPassword']")).sendKeys("admin");
            driver.findElement(By.xpath("//*[@id='btnLogin']")).click();
     
  }
 
  @AfterMethod 

// to close the browser
  public void closeb(){
      driver.close();
  }
 
}

Right click and runt he program as TestNG Test

Should launch OrangeHRM and login as Admin / admin

Once ran, on the console should display output as

Analyzing output :

Open index.html in browser and output should look like this

Next we will run Testng class file through TestNG.xml file, before that we need to create testng.xml file 

Right on the Project folder and create a file 

Sample testng.xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite guice-stage="DEVELOPMENT" name="Default suite">
  <test verbose="2" name="Default test">
    <classes>
      <class name="com.test.FirstTest"/>
    </classes>
  </test> <!-- Default test -->
</suite> <!-- Default suite -->

Here under test class tag make sure you call the proper FirstTest class file. 

Now Right click on Testng.xml file and run as TestNG Suite

That's it we have done with sample test by creating Testng file, testng.xml file and run the same as Testng Suite.

Thanks
