Question

How to demonstrate real time example of using BeforeTest, AfterTest, BeforeSuite, AfterSuite, BeforeClass, AfterClass, BeforeMethod, AfterMethod annotations in TestNG Selenium.

Answer 1

For demonstrating a real time example of using BeforeTest, AfterTest, BeforeSuite, AfterSuite, BeforeClass, AfterClass annotations through testng you don't need Selenium.

Once you install the TestNG plugin within your IDE you simply need to:

• Mention the annotations for the methods. Example:

  • @BeforeSuite
  • @BeforeClass
  • @BeforeMethod
  • @BeforeTest
  • @Test
  • @AfterTest
  • @AfterMethod
  • @AfterClass
  • @AfterSuite

• Add the relevant imports for the classes.

  • import org.testng.annotations.BeforeSuite;
  • import org.testng.annotations.BeforeClass;
  • import org.testng.annotations.BeforeMethod;
  • import org.testng.annotations.BeforeTest;
  • import org.testng.annotations.Test;
  • import org.testng.annotations.AfterTest;
  • import org.testng.annotations.AfterMethod;
  • import org.testng.annotations.AfterClass;
  • import org.testng.annotations.AfterSuite;

• Sample Code Block:

  package demo;
  
  import org.testng.annotations.AfterClass;
  import org.testng.annotations.AfterMethod;
  import org.testng.annotations.AfterSuite;
  import org.testng.annotations.AfterTest;
  import org.testng.annotations.BeforeClass;
  import org.testng.annotations.BeforeMethod;
  import org.testng.annotations.BeforeSuite;
  import org.testng.annotations.BeforeTest;
  import org.testng.annotations.Test;
  
  public class TestNG_Annotation_Demo {
  
      @BeforeSuite
      public void before_suite()
      {
          System.out.println("I am in BeforeSuite");
      }
  
      @BeforeClass
      public void before_class()
      {
          System.out.println("I am in BeforeClass");
      }
  
      @BeforeMethod
      public void before_method()
      {
          System.out.println("I am in BeforeMethod");
      }
  
      @BeforeTest
      public void before_test()
      {
          System.out.println("I am in BeforeTest");
      }
  
      @Test
      public void test()
      {
          System.out.println("I am in Test");
      }
  
      @AfterTest
      public void after_test()
      {
          System.out.println("I am in AfterTest");
      }
  
      @AfterMethod
      public void after_method()
      {
          System.out.println("I am in AfterMethod");
      }
  
      @AfterClass
      public void after_class()
      {
          System.out.println("I am in AfterClass");
      }
  
      @AfterSuite
      public void after_suite()
      {
          System.out.println("I am in AfterSuite");
      }
  }
