How to use TestNG @After Annotation?

A TestNG class can have various @After TestNG methods. Such as: @AfterTest @AfterSuite @AfterClass @AfterMethod etc.

This article will explain the order of execution of different TestNG methods.

TestNG consists of following @After methods to support main @Test method. The order of execution of @After methods should be as following:

<test1>
<AfterMethod>
<AfterClass>
<AfterTest>
<AfterSuite> 

Key Points in this Order are

• First of all, 1st @test() method is executed in above example.

• The AfterSuite() method executes only once.

• Even the methods AfterClass(), and AfterTest() methods are executed only once.

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

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. Ex:, @AfterClass, @AfterMethod, @AfterSuite

• Step 5: Now create the testNG.xml as given below.

• Step 6: Now, run the testNG.xml or directly testNG class in IDE or compile and run it using command line.

Example

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");
    }
    @AfterMethod
    public void afterMethod() {
        System.out.println("in afterMethod");
    }
    @AfterClass
    public void afterClass() {
        System.out.println("in afterClass");
    }
    @AfterTest
    public void afterTest() {
        System.out.println("in afterTest");
    }
    @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 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 test case 1
in afterMethod
in test case 2
in afterMethod
in afterClass
in afterTest
in afterSuite
