How to Run Multiple Classes Sequentially Using TestNG: A Step-by-Step Guide

In the world of software testing, automation frameworks like TestNG provide powerful tools to streamline the testing process. If you're working on a project where you need to run multiple Java classes sequentially in a single browser session, you've come to the right place! In this guide, we will explore how to configure the testng.xml file to achieve this, specifically focusing on running two sample classes: English.java and German.java.

The Problem: Running Multiple Classes in One Browser Session

Imagine you want to test a web application and need to execute two specific tests (e.g., English.java and German.java) in the same browser session. Instead of opening and closing the browser for each test, you may prefer to run them sequentially within a single instance. This not only saves time but also enhances the efficiency of your testing process. So, how can you set this up using TestNG?

The Solution: Setting Up Your TestNG Configuration

To run your tests sequentially in TestNG, you will need to create or modify a testng.xml file. This XML configuration will specify the classes to run and manage their execution order. Below are the steps to set this up:

Step 1: Create or Open Your testng.xml File

Start by creating a new testng.xml file in your project directory if you don’t have one yet. If one already exists, you can modify it accordingly.

Step 2: Configure Your XML File

You will need to structure your XML file correctly to include both test classes. Below is an example structure you can use:

Breakdown of the XML Structure

suite name: You can name your suite anything you prefer (in this case, "ABC"). The parallel="classes" attribute defines how the tests will be executed.

test name: The test tag contains the individual tests you want to run. Here, it is named "MySequentialTests", but you can choose any descriptive name.

classes: Within the classes tag, you will list all the classes you wish to execute. Note that you should specify the full package name followed by the class name, such as selenium.tests.English.

Step 3: Running Your Tests

Once you have configured your testng.xml, you can run your tests through your IDE or command line using TestNG. When you run this configuration, TestNG will launch the browser and execute the tests from the specified classes sequentially.

Conclusion

By utilizing the power of TestNG and correctly configuring your testng.xml, you can easily run multiple Java classes in a single browser session. This approach not only optimizes your testing workflow but also makes the process much more manageable and efficient.

Now that you have a clear understanding of how to set everything up, why not give it a try in your next testing project? Happy testing!
