Specify Method Name Sequence in TestNG

A TestNG class can have various TestNG methods such as @BeforeTest, @AfterTest, @BeforeSuite, @BeforeClass, @BeforeMethod, @test, etc. In this article, we will explain the order of execution of different TestNG methods.

TestNG consists of the following methods to support the main @Test method. The order of execution should be as follows −

<beforeSuite>
<beforeTest>
<beforeClass>
<beforeMethod>
<test1>
<afterMethod>
<afterClass>
<afterTest>
<afterSuite>

Key points in this order are:

• First of all, beforeSuite() method is executed only once.

• The afterSuite() method executes only once.

• Even the methods beforeTest(), beforeClass(), afterClass(), and afterTest() methods are executed only once.

• beforeMethod() method executes for each test case (every time for a new @Test), but before executing the test case.

• afterMethod() method executes for each test case (every time for a new @Test), but after executing the test case.

• In between beforeMethod() and afterMethod(), each test case (@Test annotation’s method) executes.

Approach/Algorithm to solve this problem:

• Step 1 − import org.testng.annotations.* for TestNG.

• Step 2 − Write an annotation as @test

• Step 3 − Create a method for the @test annotation as test1.

• Step 4 − Repeat the steps for test2 and test3.

• Step 5 − Write different annotations and their respective methods. For example, @beforeSuite, @afterSuite, @beforeTest, @afterTest, @beforeClass, @afterClass, @beforeMethod, @afterMethod.

• Step 6 − Now create the testNG.xml as given below.

• Step 7 − Finally, run the testNG.xml or directly testNG class in IDE or compile and run it using command line.

Example

Use the following code to show the order of different TestNG methods −

import org.testng.annotations.*;
import org.testng.annotations.Test;
public class OrderofTestExecutionInTestNG {
   // 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");
   }
}

testng.xml

This is a configuration file that is used to organize and run the TestNG test cases. It is very handy when limited tests are needed to execute rather than the full suite.

<?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 = "OrderofTestExecutionInTestNG"/>
      </classes>
   </test>
</suite>

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
