@Optional in TestNG Parameter is overriding the values that I'm passing in XML

Question

When I try to use multiple parameters using @Parameter, @Optional needs to pass the value only when I'm not providing the value for the parameter in testng XML.

But in the below scenario, no matter what I pass in the XML for the "Optional" parameter the values that I've given in @Optional is being taken into consideration.

XML that I'm using:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
    <suite name="Cross Browser Multi-Paramet - Suite">

    
    <test name="Cross Browser Multi-Paramet - Firefox Test">
    <parameter name="Browser" value="Firefox" />
    <parameter name="URL" value="https://www.oneplus.in/" />
    <classes>
        <class name="CrossBrowser.CrossBrowserMultipleParamter">
        </class>

    </classes>


</test> <!-- Cross Browser Multi-Paramet - Test -->
</suite> <!-- Cross Browser Multi-Paramet - Suite -->

And the code is:

package CrossBrowser;

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Optional;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class CrossBrowserMultipleParamter {

public static WebDriver d;

@Test
@Parameters({ "Broswer", "URL" })
public static void cbmultpara(@Optional("Chrome") String browsername, String siteurl) throws Exception {

    if (browsername.equalsIgnoreCase("Firefox")) {
        System.out.println("Browser name is" + browsername);
        d = new FirefoxDriver();
    } else if (browsername.equalsIgnoreCase("Chrome")) {
        System.out.println("Browser name is" + browsername);
        d = new ChromeDriver();
    }
    d.manage().window().maximize();
    d.get(siteurl);
    System.out.println("Loaded the page sucessfully");
    d.quit();
}

}

Though I'm passing value as "Firefox" it is launching Chrome.

Can someone clarify?.

In order load the parameters from the testng.xml properly, you need to add surefire plugin configuration as shown below in your pom.xml file. Please verify that and let me know if you still face the same issue.

Note: Please mark this answer as accepted, if it is helpful.

POM.xml:

I'm using the right packages and the browser name is being displayed as "Chrome". No matter what I pass in the XML, it launches Chrome. – Surendra Anand Sep 10 '20 at 07:12
Could you please share the entire test case class content with us. – UnknownBeast Sep 10 '20 at 07:14
So how are you running the project? Have you configured testng.xml in pom file or you are running the class file directly? – UnknownBeast Sep 10 '20 at 07:25
And when I use one parameter using @Parameter, it works like a charm. – Surendra Anand Sep 10 '20 at 07:27
I'm running the xml file. – Surendra Anand Sep 10 '20 at 07:28
If you run pom.xml file without surefire configuration in it then the parameters will not get loaded properly. Please try to update the pom.xml same as mentioned in the answer and let me know if you face the same issue – UnknownBeast Sep 10 '20 at 07:32
Let us [continue this discussion in chat](https://chat.stackoverflow.com/rooms/221248/discussion-between-surendra-anand-and-unknownbeast). – Surendra Anand Sep 10 '20 at 07:39
Can we have the surefire configured in testng.xml file. I'm trying to implement it without maven. – Surendra Anand Sep 10 '20 at 09:19
