TestNG

TestNG

TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing (testing a class in isolation of the others) to integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers).

1. Create project in Eclispse
2. Install TestNG plugin Ecliplse marketplace
3. Include selenium TestNG jar
4. Create class 1 and and class 2 as below
5. Run the test suit using TestNG suite


Class1.java
---------------------------

import org.testng.annotations.AfterClass;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class Class1 {
   
   
    @BeforeClass()
    public void beforeclass(){
    System.out.println(" Beforecall from class 1");
    System.out.println("-------------------------------------");
    }
   
       
    @BeforeMethod
    public void welcome(){
    System.out.println("Open Browser-- Beforemethod is called in class 1");
   
    }
    @Test
    public void Register(){
//    throw new SkipException("Skipping the test");
    System.out.println("Registering user - Test 1");
    }
   
    @Test   
    public void Login(){       
    System.out.println("Test Login - Test 2");
    }
   
    @Test
    public void change_password(){
    System.out.println("Password change - Test 3");
    }
   
    @AfterMethod
    public void  logout(){
    System.out.println("Close Browser -  Aftermethod is called in class 1");
    System.out.println("------------------------------");
    }
   
    @AfterClass
    public void after_class(){
    System.out.println("destroy driver in call 1");
    System.out.println("-------------------------------------");
    }
}   

Class2.java
----------------------

import org.testng.Assert;
import org.testng.annotations.AfterClass;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;


public class Class2 {
   
    @BeforeSuite
    public void beforesuit(){
    System.out.println("@BeforeSuite - written in class 2");
    }
   
    @BeforeTest
    public void beforetest(){
        System.out.println("This is before test - @BeforeTest written in class 2");       
    }
   
    @BeforeClass()
    public void beforeclass(){
    System.out.println(" @beforeClass- Initialize driver for class 2");
    }
   
    @Test
    public void add_user(){
    System.out.println(" Test 1  in class 2");       
    }
   
    @AfterClass
    public void after_class(){
    System.out.println("@AfterClass - destroy driver in call 2");
    System.out.println("-------------------------------------");
    }
   
    @AfterSuite
    public void aftersuit(){
    System.out.println("@AfterSuite - written in class 2");
    }
}

OP:

@BeforeSuite - written in class 2
This is before test - @BeforeTest written in class 2
 Beforecall from class 1
-------------------------------------
Open Browser-- Beforemethod is called in class 1
Test Login - Test 2
Close Browser -  Aftermethod is called in class 1
------------------------------
Open Browser-- Beforemethod is called in class 1
Registering user - Test 1
Close Browser -  Aftermethod is called in class 1
------------------------------
Open Browser-- Beforemethod is called in class 1
Password change - Test 3
Close Browser -  Aftermethod is called in class 1
------------------------------
destroy driver in call 1
-------------------------------------
 @beforeClass- Initialize driver for class 2
 Test 1  in class 2
@AfterClass - destroy driver in call 2
