Some basic annotation of TestNG

Below are some basic annotation which we use in automation.
 

@BeforeSuite - Execute only one time before all testNg method..

@AfterSuite - Execute only one time after all testNg method.

@BeforeClass - Execute only one time before first test and after @BeforeSuite testNg method.

@AfterClass - Execute only one time after last test and before @AfterSuite testNg method.

@BeforeMethod - Execute before every @Test methods.

@AfterMethod - Execute after every @Test methods.

@Test – TestNG test method.

Below is example for the TestNG annotations:

package com.test;

import org.testng.annotations.*;

public class TestNGBasicAnnotation {

   @BeforeSuite

   public void suite(){

      System.out.println("@Befor Suite - one time executed before any testNG function");

   }

  

   @AfterSuite

   public void afterSuite(){

      System.out.println("@After Suite - one time executed after all testNg function");

   }

   @BeforeClass

   public void beforeClass() {

        // one-time initialization code

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

   }

   @AfterClass

   public void afterClass() {

      // one-time cleanup code

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

   }

   @BeforeMethod

   public void setUp() { 

       System.out.println("@BeforeMethod - executed before all test method");

   }

   @AfterMethod

   public void tearDown() { 

       System.out.println("@AfterMethod - executed after all test methods");

   }

  

   @Test

   public void testFirstMethod() {   

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

   }

   @Test

   public void testSecondMethod() {   

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

   }

}

Below are the execution log after executing above TestNG class. 

@Befor Suite - one time executed before any testNG function

@BeforeClass - one time executed before first mathod

@BeforeMethod - executed before all test method

@Test - executed first test method

@AfterMethod - executed after all test methods

@BeforeMethod - executed before all test method

@Test - executed second test method

@AfterMethod - executed after all test methods

@AfterClass - one time executed after last method
@AfterSuite - one time executed after all testNg functions

PASSED: testFirstMethod

PASSED: testSecondMethod
