06. TestNG Annotations – Hierarchy or Levels

TestNG Annotations – Hierarchy or Levels

Annotations hierarchy or Annotations levels in TestNG.

It says that @Test is the smallest annotation here. @Method will be executed first, before and after the execution of @Test. The same way @Class will be executed first, before and after the execution of @Method and so on.

Easily understand once we run the below code.

package Others;

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_Annotations {

                        @Test

                        public void testCase1() {

                                    System.out.println("This is the Test Case 1");

                        }

                        @Test

                        public void testCase2() {

                                    System.out.println("This is the Test Case 2");

                        }

                        @BeforeMethod

                        public void beforeMethod() {

                                    System.out.println("This will execute before every Method");

                        }

                        @AfterMethod

                        public void afterMethod() {

                                    System.out.println("This will execute after every Method");

                        }

                        @BeforeClass

                        public void beforeClass() {

                                    System.out.println("This will execute before the Class");

                        }

                        @AfterClass

                        public void afterClass() {

                                    System.out.println("This will execute after the Class");

                        }

                        @BeforeTest

                        public void beforeTest() {

                                    System.out.println("This will execute before the Test");

                        }

                        @AfterTest

                        public void afterTest() {

                                    System.out.println("This will execute after the Test");

                        }

                        @BeforeSuite

                        public void beforeSuite() {

                                    System.out.println("This will execute before the Test Suite");

                        }

                        @AfterSuite

                        public void afterSuite() {

                                    System.out.println("This will execute after the Test Suite");

                        }

            }

To Get the below response once we run the above code.

Output:

This will execute before the Test Suite

This will execute before the Test

This will execute before the Class

This will execute before every Method

This is the Test Case 1

This will execute after every Method

This will execute before every Method

This is the Test Case 2

This will execute after every Method

This will execute after the Class

This will execute after the Test

PASSED: testCase1

PASSED: testCase2

In Output,clearly visible that the @Suite annotation is the very first and the very lastly executed. Then @Test followed by @Class.

Now if you notice, the @Method has executed twice. As @Test is a method in the class, hence @Method will always executed for each @Test method.
