You can consider something like the below as a possible solution
package com.rationaleemotions.stackoverflow;
import org.testng.IAlterSuiteListener;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import org.testng.collections.Maps;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlSuite;
import org.testng.xml.XmlTest;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
public class MultiBrowserSample {
@Test
@Parameters("browser")
public void testMethod(String browser) {
System.err.println("Browser : " + browser + " on Thread [" + Thread.currentThread().getId() + "]");
}
public static class MySuiteAlterer implements IAlterSuiteListener {
@Override
public void alter(List<XmlSuite> suites) {
XmlSuite suite = suites.get(0);
//Check if there was a parameter named "browserFlavors" defined at the suite
String browserFlavors = suite.getParameter("browserFlavors");
if (browserFlavors == null || browserFlavors.trim().isEmpty()) {
//If no such parameter was found, then Try querying the JVM arguments to see if it contains
//value for it. Just to ensure we don't end up in a situation wherein there's no JVM also provided
//Lets add a default value for the JVM argument which in our case is "firefox"
browserFlavors = System.getProperty("browserFlavors", "firefox");
}
String[] browsers = browserFlavors.split(",");
List<XmlTest> xmlTests = new ArrayList<>();
for (String browser : browsers) {
XmlTest xmlTest = new XmlTest(suite);
xmlTest.setName(browser + "_test");
Map<String, String> parameters = Maps.newHashMap();
parameters.put("browser", browser);
xmlTest.setParameters(parameters);
XmlClass xmlClass = new XmlClass();
xmlClass.setName(MultiBrowserSample.class.getCanonicalName());
xmlTest.getClasses().add(xmlClass);
xmlTests.add(xmlTest);
}
suite.setTests(xmlTests);
}
}
}
The suite xml file can look like below
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="1265_Suite" parallel="tests" verbose="2">
<listeners>
<listener class-name="com.rationaleemotions.stackoverflow.MultiBrowserSample$MySuiteAlterer"/>
</listeners>
<!--
If the below line gets uncommented, then 3 <test> tags will be formed one for each browser flavor.
Since its now commented, you will have to provide a value for it via the JVM argument
-DbrowserFlavors=firefox,chrome,ie (or) the system will default to just working with firefox
-->
<!--<parameter name="browserFlavors" value="firefox,chrome,ie"/>-->
</suite>
So as you can see, here we are resorting to using a TestNG listener called IAlterSuiteListener
implementation which is going to help us construct the <test>
tags in the suite xml file dynamically and the number of <test>
tags in the suite xml file will be directly equal to the number of browsers specified either via the suite level parameter browserFlavors
(or) via the JVM argument -DbrowserFlavors
The output would be as below

According to netmarketshare, Google Chrome accounts for 67% of the browser market share. It is the choice of the majority of users and it’s popularity continues to rise. This is why, as an automation tester, it is important that you perform automated browser testing on Chrome browser.

Cross browser testing has been a type of testing which requires a tremendous amount of effort and time. The process of testing your web-app over different browsers, operating systems, devices, screen resolutions to evaluate the rendering of your web content for a variety of your audience is an activity. Especially, if approached manually. Automated cross browser testing with Selenium can help you save the time of routine test activities, helping you cut short on regression testing. However, people seldom like changes. If manual testing is popular in your organization, the management will obviously raise questions when you ask them to implement test automation.
TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.
You can push your abilities to do automated testing using TestNG and advance your career by earning a TestNG certification. Check out our TestNG certification.
Watch this complete tutorial to learn how you can leverage the capabilities of the TestNG framework for Selenium automation testing.
