TestNG Groups in Selenium Java – Complete Guide

By Bhau Automation • Learn how to group and run test methods efficiently

🎯 What You Will Learn in This Tutorial

What are TestNG groups and why they are useful
How to group test methods from different classes
Running Smoke, Sanity, and Regression tests using groups
Using and tags in testng.xml
BeforeGroups and AfterGroups annotations
Running multiple suites and specifying groups
Real-world examples and best practices

💡 Pro Tip: Grouping tests reduces execution time and allows better organization for large test suites.

📌 What Are TestNG Groups?

TestNG Groups allow you to categorize your test methods and selectively run them. This is particularly useful when you have multiple test classes and want to run a specific set of tests like smoke or regression tests.

Run specific tests from multiple classes
Organize tests into logical groups (e.g., Smoke, Regression, Sanity)
Enable selective execution in CI/CD pipelines

🔧 How to Define and Use TestNG Groups

Here’s an example of grouping test methods in Selenium:

import org.testng.annotations.Test;

public class LoginTest {
    
    @Test(groups = {"smoke","regression"})
    public void loginValidUser() {
        System.out.println("Login test for valid user");
    }

    @Test(groups = {"regression"})
    public void loginInvalidUser() {
        System.out.println("Login test for invalid user");
    }
}

public class SearchTest {
    
    @Test(groups = {"smoke"})
    public void searchProduct() {
        System.out.println("Search product test");
    }

    @Test(groups = {"regression"})
    public void searchEmptyCart() {
        System.out.println("Search with empty cart test");
    }
}

📋 Running Groups from testng.xml

You can include or exclude groups in your testng.xml file:

🔄 Using BeforeGroups and AfterGroups

TestNG allows setup and teardown specifically for groups:

import org.testng.annotations.*;

public class GroupSetup {

    @BeforeGroups("smoke")
    public void beforeSmokeGroup() {
        System.out.println("Setup for Smoke tests");
    }

    @AfterGroups("smoke")
    public void afterSmokeGroup() {
        System.out.println("Cleanup after Smoke tests");
    }
}

🎯 Benefits of Using TestNG Groups

Run only required tests to save execution time
Organize large test suites logically
Enable targeted execution in CI/CD pipelines
Combine multiple classes in a single group

❓ Common Interview Questions

Q: How do you group test cases in TestNG?

A: Use the groups attribute in @Test annotations and configure include/exclude in testng.xml.

Q: Can a test method belong to multiple groups?

A: Yes, a test method can belong to multiple groups by providing an array of group names.

🎓 Key Takeaways

TestNG groups allow selective and efficient execution of tests
Include and exclude groups in testng.xml for better control
Use BeforeGroups and AfterGroups for group-specific setup/teardown
Grouping helps in organizing large suites and improving CI/CD pipelines

⚡ Next Steps: Practice creating groups for your own test suites and run selective tests using testng.xml.
