TestNG Groups Test

In this tutorial, we will show you how to do the group testing in TestNG.

1. Groups on Methods

Review a test group example.

1. runSelenium() and runSelenium1() are belong to group selenium-test.
2. testConnectOracle() and testConnectMsSQL() are belong to group database.
3. runFinal() will be executed if groups selenium-test and database are passed.

package com.mkyong.testng.examples.group;
import org.testng.annotations.AfterGroups;
import org.testng.annotations.BeforeGroups;
import org.testng.annotations.Test;
public class TestGroup {
	@BeforeGroups("database")
	public void setupDB() {
		System.out.println("setupDB()");
	@AfterGroups("database")
	public void cleanDB() {
		System.out.println("cleanDB()");
	@Test(groups= "selenium-test")
	public void runSelenium() {
		System.out.println("runSelenium()");
	@Test(groups= "selenium-test")
	public void runSelenium1() {
		System.out.println("runSelenium()1");
	@Test(groups = "database")
	public void testConnectOracle() {
		System.out.println("testConnectOracle()");
	@Test(groups = "database")
	public void testConnectMsSQL() {
		System.out.println("testConnectMsSQL");
	@Test(dependsOnGroups = {"database","selenium-test"})
	public void runFinal() {
		System.out.println("runFinal");

Output

//group = selenium-test
runSelenium()
runSelenium()1
//group = database
setupDB()
testConnectMsSQL
testConnectOracle()
cleanDB()
//dependsOnGroups = database, selenium-test
runFinal
PASSED: runSelenium
PASSED: runSelenium1
PASSED: testConnectMsSQL
PASSED: testConnectOracle
PASSED: runFinal

2. Groups on Class

The “Group” can be applied on class level. In below example, every public method of this class “TestSelenium” is belong to group selenium-test.

package com.mkyong.testng.examples.group;
import org.testng.annotations.Test;
@Test(groups= "selenium-test")
public class TestSelenium {
	public void runSelenium() {
		System.out.println("runSelenium()");
	public void runSelenium1() {
		System.out.println("runSelenium()1");

Create an XML file to run 2 test classes.

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="TestAll">
	<test name="final">
		<classes>
			<class name="com.mkyong.testng.examples.group.TestSelenium" />
			<class name="com.mkyong.testng.examples.group.TestGroup" />
		</classes>
	</test>
	<!-- Run test method on group "selenium" only -->
	<test name="selenium">
		<groups>
			<run>
				<include name="selenium-test" />
			</run>
		</groups>
		<classes>
			<class name="com.mkyong.testng.examples.group.TestSelenium" />
			<class name="com.mkyong.testng.examples.group.TestGroup" />
		</classes>
	</test>
</suite>

Output

//test name = final
runSelenium()
runSelenium()1
setupDB()
testConnectMsSQL
testConnectOracle()
cleanDB()
runFinal
//test name = selenium
runSelenium()
runSelenium()1
===============================================
TestAll
Total tests run: 7, Failures: 0, Skips: 0
===============================================

3. Misc Examples

3.1 A test method can belong to multiple groups.

	@Test(groups = {"mysql","database"})
	public void testConnectMsSQL() {
		System.out.println("testConnectMsSQL");

3.2 The above result is executed via Eclipse TestNG Plugin.
