How to exclude a specific TestNG test Groups via Maven?
TestNG is a testing framework and can use Maven as build tool. It helps to maintain dependencies and their version at one place in pom.xml
Maven provides flexibility to include or exclude a test group at run time. User can exclude test group or groups at run time in maven using surefire plugin.
In this article we will illustrate how to exclude a test group via surefire at runtime.
Approach/Algorithm to solve this problem
Step 1: Create a TestNG classes − NewTestngClass
Step 2: Write 2 @Test method in the class with group name.
Step 3: Now create the testNG.xml as given below where group details are not mentioned.
Step 4: Don’t add group name that should exclude after suiteXMLFiles in pom.xml as shown in program section.
Step 5: Now, run it using command line.
Example
The following code to show how to run only 1 test method from a large suite:
src/ NewTestngClass.java
import org.testng.annotations.Test;
public class NewTestngClass {
@Test(groups = { "group1", "group3" })
public void testCase1() {
System.out.println("in test case 1 of NewTestngClass");
}
@Test(groups = { "group2", "group3" })
public void testCase1() {
System.out.println("in test case 2 of NewTestngClass");
}
}
pom.xml
This is a maven configuration file that is used to organize dependencies, plugins and run the TestNG test cases.
It is very handy when limited tests are needed to execute rather than full suite.
If user wants to exclude groups in pom.xml then he/she should have to add <excludedGroups>group1,group2</excludedGroups> after the </suiteXmlFiles> tag. In this case user need not to pass command line paramaeter.

mvn test -DexcludedGroups=group1
