TestNG - Execution Procedure

This chapter explains the execution procedure of methods in TestNG. It explains the order of the methods called. Here is the execution procedure of the TestNG test API methods with an example.
Create a java class file name TestngAnnotation.java in in /work/testng/src to test annotations.
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.AfterSuite;

public class TestngAnnotation {
   // test case 1
   @Test
   public void testCase1() {
      System.out.println("in test case 1");
   }

   // test case 2
   @Test
   public void testCase2() {
      System.out.println("in test case 2");
   }

   @BeforeMethod
   public void beforeMethod() {
      System.out.println("in beforeMethod");
   }

   @AfterMethod
   public void afterMethod() {
      System.out.println("in afterMethod");
   }

   @BeforeClass
   public void beforeClass() {
      System.out.println("in beforeClass");
   }

   @AfterClass
   public void afterClass() {
      System.out.println("in afterClass");
   }

   @BeforeTest
   public void beforeTest() {
      System.out.println("in beforeTest");
   }

   @AfterTest
   public void afterTest() {
      System.out.println("in afterTest");
   }

   @BeforeSuite
   public void beforeSuite() {
      System.out.println("in beforeSuite");
   }

   @AfterSuite
   public void afterSuite() {
      System.out.println("in afterSuite");
   }

}
Next, let's create the file testng.xml in in /work/testng/src to execute annotations.
<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name = "Suite1">
   <test name = "test1">
      <classes>
         <class name = "TestngAnnotation"/>
      </classes>
   </test>
</suite>
Compile the Test case class using javac.
/work/testng/src$ javac TestngAnnotation.java

Now, run the testng.xml, which will run the test case defined in the provided Test Case class.
/work/testng/src$ java org.testng.TestNG testng.xml

Verify the output.
in beforeSuite
in beforeTest
in beforeClass
in beforeMethod
in test case 1
in afterMethod
in beforeMethod
in test case 2
in afterMethod
in afterClass
in afterTest
in afterSuite

===============================================
Suite
Total tests run: 2, Failures: 0, Skips: 0
===============================================

Based on the above output, the execution procedure is as follows −
First of all, beforeSuite() method is executed only once.
First of all, beforeSuite() method is executed only once.
Lastly, the afterSuite() method executes only once.
Lastly, the afterSuite() method executes only once.
Even the methods beforeTest(), beforeClass(), afterClass(), and afterTest() methods are executed only once.
Even the methods beforeTest(), beforeClass(), afterClass(), and afterTest() methods are executed only once.
beforeMethod() method executes for each test case but before executing the test case.
beforeMethod() method executes for each test case but before executing the test case.
afterMethod() method executes for each test case but after executing the test case.
afterMethod() method executes for each test case but after executing the test case.
In between beforeMethod() and afterMethod(), each test case executes.
In between beforeMethod() and afterMethod(), each test case executes.
