You can use the -xmlpathinjar suites/GroupBased_Tests.xml option to run your xml.
Can refer steps with maven here, if it helps.

For other options you can use, please refer Testng documentation here.

you want to execute the jar programmatically? – niharika_neo Mar 01 '16 at 05:51
yes.i have a jar file that generated from maven build.let say my jar file name is `myproject-1.0-SNAPSHOT` this jar contains all of my `src/target` folder resources.so i want to execute my `testngTestfile.xml` that is located inside that generated jar file.i want to do it programmatically.Eg:user give jar with file name as a arg and execute that test programmatically.`executeTest(.jarfilelocation,fileNametobeExecuted)`.inside this method test will be run. – gihan-maduranga Mar 01 '16 at 05:59

Probably this can help..http://stackoverflow.com/questions/1320476/execute-another-jar-in-a-java-program..that would be a separate question then – niharika_neo Mar 01 '16 at 06:02
thanks.As far as u know is there any facility in TestNG to run test against a jar programmatically? – gihan-maduranga Mar 01 '16 at 06:08
you can run your tests in testng programmatically too without packaging in a jar, if that is what you are asking – niharika_neo Mar 01 '16 at 06:16
no.can we run test against a given jar file programmatically?.or do i need to extract jar and give physical file into TestNG? – gihan-maduranga Mar 01 '16 at 06:19
No the above answer would help there..the link that i shared above – niharika_neo Mar 01 '16 at 07:00

jar is a just a zip file.

You can get that extracted using jar xf testfile.jar and access the file you want.

This answer also might help you.

Read a file from inside of an external Jar file?

You can read the testng.xml and also run it programmatically without extracting the jar.

First you need to read the xml and parse it. Here I have created some bean classes to match with my xml file format. This is my bean class, create you own set of classes which match with your requirement

@XmlRootElement(name = "suite")
public class Suite {

private String name;
private String verbose = "1";
private boolean parallel =false;

private List<Test> testCases = new ArrayList<Test>();
private List<Parameter> parameters = new ArrayList<Parameter>();

@XmlAttribute
public String getName() {
    return name;
}


public void setName(String name) {
    this.name = name;
}

@XmlAttribute
public String getVerbose() {
    return verbose;
}


public void setVerbose(String verbose) {
    this.verbose = verbose;
}

@XmlAttribute
public boolean isParallel() {
    return parallel;
}


public void setParallel(boolean parallel) {
    this.parallel = parallel;
}

@XmlElement(name = "test")
public List<Test> getTestCases() {
    return testCases;
}

public void setTestCases(List<Test> testCases) {
    this.testCases = testCases;
}

@XmlElement(name = "parameter")
public List<Parameter> getParameters() {
    return parameters;
}


public void setParameters(List<Parameter> parameters) {
    this.parameters = parameters;
}
}

And this is how you read and parse it:

public Suite getTestSuiteFromJar(String jarFilePath, String filename) {
    File jarFile  = new File(jarFilePath);
    Suite suite = null;
    try {
        if (jarFile.isFile()) {
            final JarFile jar = new JarFile(jarFile);

            InputStream in = jar.getInputStream(new ZipEntry(filename));
            suite = XmlUtil.parseSuite(in);
            jar.close();
        }

    } catch (IOException | JAXBException | SAXException | ParserConfigurationException e) {
        e.printStackTrace();
    }
    return suite;
}

public static Suite parseSuite(InputStream is) throws JAXBException, SAXException, ParserConfigurationException {
    JAXBContext jaxbContext = JAXBContext.newInstance(Suite.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
    return (Suite) jaxbUnmarshaller.unmarshal(is);
}

Finally we run the suite:

public static void runSuite(String jarFilePath, Suite s)
        throws MalformedURLException, ClassNotFoundException {
    //Don't confuse : XmlSuite here, is the standard testNg class. our bean class is Suite
    XmlSuite suite = new XmlSuite();
    suite.setName(s.getName());

    for (Test t : s.getTestCases()) {
        XmlTest test = new XmlTest(suite);
        test.setName(t.getName());
        List<XmlClass> classes = new ArrayList<XmlClass>();
        for (TestClass tc : t.getClasses()) {
            Class cls =  loadClass(jarFilePath, tc.getName());
            if (cls != null) {
                XmlClass xClass = new XmlClass(cls, false);
                classes.add(xClass);
                test.setXmlClasses(classes);
            }
        }
    }
    List<XmlSuite> suites = new ArrayList<XmlSuite>();

    suites.add(suite);
    TestNG tng = new TestNG();

    tng.setXmlSuites(suites);
    tng.run();
}

public Class loadClass(String jarFilePath, String className) throws MalformedURLException,
        ClassNotFoundException {
File jarFile  = new File(jarFilePath);
    if (jarFile.isFile()) {
        URL url = jarFile.toURL();
        URL[] urls = new URL[] { url };
        ClassLoader cl = new URLClassLoader(urls);
        return cl.loadClass(className);
    } else {
        return null;
    }
}
