TestNG Groups

What Are TestNG Groups ?

TestNG groups imply the process of grouping more than one tests together into a single set which can be executed in a single command.Tests can belong to different different classes.

We define a group in our .xml and then pass this group name with test annotations.

Syntax :

@Test(groups = { "GroupName" })

Multiple group name can be passed in a test annotation by separating each group name with ' , ' .

@Test(groups = { "GroupName1","GroupName2" })

Groups are created at these two levels :

Suite Level : Groups are defined in <suite> tag that apply on all the <test> tag in .xml.

Class Level : Groups are defined in <test> tag that apply only on that particular <test> tag in .xml.

Let's create two example classes as TestNGGroupExample1 and TestNGGroupExample2 :

TestNGGroupExample1 :

package testNGexamples;

import org.testng.annotations.Test;

public class TestNGGroupExample1 {

@Test(groups = { "Test Group In Suite" })
public void test1() {
System.out.println("test1 of Test Group In Suite is executing :");
}

@Test(groups = { "Test Group In Test" })
public void test2() {
System.out.println("test2 of Test Group In Test is executing :");

}

TestNGGroupExample2 :

package testNGexamples;

import org.testng.annotations.Test;

public class TestNGGroupExample2 {

@Test(groups = { "Test Group In Test" })
public void test3() {
System.out.println("test3 of Test Group In Test is executing :");

}

@Test(groups = { "Test Group In Suite" })
public void test4() {
System.out.println("test4 of Test Group In Suite is executing :");

}

Now group the tests of these classes at suite and class level.

.XML for testNG group at suite level :

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Test-Suite">
<groups>
<run>
<include name="Test Group In Suite"></include>
</run>
</groups>
<test name="Group Test1">
<classes>
<class name="testNGexamples.TestNGGroupExample1"></class>
</classes>
</test>
<test name="GroupTest2">
<classes>
<class name="testNGexamples.TestNGGroupExample2"></class>
</classes>
</test>
</suite>

Output :

[RemoteTestNG] detected TestNG version 7.4.0
test1 of Test Group In Suite is executing :
test4 of Test Group In Suite is executing :

===============================================
Test-Suite
Total tests run: 2, Passes: 2, Failures: 0, Skips: 0
===============================================

.XML for testNG group at class level :

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Test-Suite">
<test name="Group Test">
<groups>
<run>
<include name="Test Group In Test"></include>
</run>
</groups>
<classes>
<class name="testNGexamples.TestNGGroupExample1"></class>
<class name="testNGexamples.TestNGGroupExample2"></class>
</classes>
</test>
</suite>

Output :

[RemoteTestNG] detected TestNG version 7.4.0
test2 of Test Group In Test is executing :
test3 of Test Group In Test is executing :

===============================================
Test-Suite
Total tests run: 2, Passes: 2, Failures: 0, Skips: 0
===============================================

TestNG supports nested group as well that is a group inside another group.

In .xml we have to define the nested group within <group> tag and then include it inside <run> .

</define>

<run>

</run>

</groups>
