Selenium grid or TestNG XML for parallel cross browser testing

Question

I am trying to do some cross browser testing on selenium by connecting to browser stack so that I can test on multiple browsers at the same time.

At the moment I am using a testng xml file to set up my browsers for testing (see code below) and running my tests from there in parallel.

I will possibly be doing this for at least 15 different browser/device types and was wondering if it is a good idea to continue using this approach. Or will selenium grid be better? Any suggestions will be appreciated :)

testng xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite thread-count="2" name="test.java" verbose="1" annotations="JDK" parallel="tests" >
    <test name="Test - Chrome">
        <parameter name="browser" value="chrome"/>
        <parameter name="browserVersion" value="74.0 beta"/>
        <parameter name="os" value="OS X"/>
        <parameter name="osVersion" value="Mojave"/>
        <parameter name="resolution" value="1024x768"/>
        <classes>
            <class name="EndToEnd"/>
        </classes>
    </test>

    <test name="Test - Firefox">
        <parameter name="browser" value="firefox"/>
        <parameter name="browserVersion" value="66"/>
        <parameter name="os" value="OS X"/>
        <parameter name="osVersion" value="Mojave"/>
        <parameter name="resolution" value="1024x768"/>
        <classes>
            <class name="EndToEnd"/>
        </classes>
    </test>
</suite>

set up class:

@BeforeTest
    @Parameters({"browser", "browserVersion", "os", "osVersion", "resolution"})
    public void setUp(String browser, String browserVersion, String os, String osVersion, String resolution) throws Exception
    {
        DesiredCapabilities capability= new DesiredCapabilities();
        capability.setCapability("browser", browser);
        capability.setCapability("browser_version", browserVersion);
        capability.setCapability("os", os);
        capability.setCapability("os_version", osVersion);
        capability.setCapability("resolution", resolution);
        capability.setCapability("browserstack.local", "true");
        capability.setCapability("browserstack.localIdentifier", "Test123");
        driver = new RemoteWebDriver(new URL(URL), capability);
    }

To be honest I would setup the hub with different nodes capabilities and just let the grid to distribute that across the nodes rather than having it in test NG.

There is a good article here , which might help you understand better .
