Maven + TestNG Print parameters of @DataProvider

Question

The question is simple but I can't find it anywhere (googling) I want to run mvn test and see in the console output the next text "PASSED: theNameOfMyTest("A String Attribute")" the code that will produce this example would look something like this:

import static org.testng.Assert.assertTrue;

public class TestClass {

    @DataProvider(name = "provider")
    public static Object[][] provider() {
        return new Object[][] {{"A String Attribute"}};
    }

    @Test(dataProvioder="provider")
    public void theNameOfMyTest(final String parameter) {
        assertTrue(true);
    }

}

You can use your own Listener which will display the expected information. Then, configure surefire to use it: https://maven.apache.org/surefire/maven-surefire-plugin/examples/testng.html

public class MyTestListener extends TestListenerAdapter {

  @Override
  public void onTestFailure(ITestResult tr) {
    log("FAIL: ", tr);
  }

  @Override
  public void onTestSkipped(ITestResult tr) {
    log("SKIPPED: ", tr);
  }

  @Override
  public void onTestSuccess(ITestResult tr) {
    log("PASSED: ", tr);
  }

  private static void log(String prefix, ITestResult tr) {
    System.out.println(prefix + tr.getName() + "(" + Arrays.asList(tr.getParameters()) + ")");
  }
}

In your pom.xml:
