@Test is not executing - If I add TestNG Listener in test xml file, my @Test methods are not executing

I'm using TestNG and for reporting using extent report. I'm trying to add TestNG Listeners to perform some operation on Success and on Failure. I have created a Test Listener class and mentioned listener in suite file.Issue is Test is not executing and console says Test run =0 ; If is remove listener tag from suite xml file, it works like charm.

Listener class

public class TestListener implements ITestListener
{

    @Override
    public void onTestStart(ITestResult result) 
    {
        // TODO Auto-generated method stub
        System.out.println("OnTestStart");

    }

    @Override
    public void onTestSuccess(ITestResult result) 
    {
        // TODO Auto-generated method stub
        Reporter.log(Status.INFO, "Passed");

    }

    @Override
    public void onTestFailure(ITestResult result) 
    {
        // TODO Auto-generated method stub
        Reporter.log(Status.INFO, "Failed");
    }
}

Base Test

public class BaseTest 
{
    @BeforeSuite
    public void preStep(ITestContext txt)
    {
        System.out.println("in before suite");
        Reporter.startReport(txt);
        System.out.println("out");
    }
    @BeforeMethod(alwaysRun=true)
    public void setUp()
    {
        System.out.println("Before Method");
        Reporter.setup();
    }
    @AfterMethod
    public void closeUp(ITestResult tr)
    {
        System.out.println("After Method");
    }
    @AfterSuite
    public void postStep()
    {
        System.out.println("After Suite");
    }
}

Test class

public class TestScripts extends BaseTest
{

    @Test
    @Parameters("Browser")
    public void loginScenario(String browser)
    {
        LoginPageSteps lp = new LoginPageSteps(browser);
        lp.loginScenario();
    }
    @Test
    @Parameters("Browser")
    public void a(String browser)
    {
        Reporter.log(Status.PASS, "A Passed");
    }
    @Test
    @Parameters("Browser")
    public void b(String browser)
    {
        Reporter.log(Status.ERROR, "B Failed");
    }
    @Test
    @Parameters("Browser")
    public void c(String browser)
    {
        Reporter.log(Status.ERROR, "C Failed");
    }
}

Suite File

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite thread-count="10" name="Default Suite" parallel="tests">

It seems that there is issue with your Listener class and Reporter class import statement .

If your are using Reporter class of TestNG then there is no such method as "setup" or start

I am able to run the script by modifying your TestListener and BaseTest class as follows:

package stackoverflow;

import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;

public class TestListener implements ITestListener {

@Override
public void onTestStart(ITestResult iTestResult) {
    System.out.println("onTestStart");
}

@Override
public void onTestSuccess(ITestResult iTestResult) {
    System.out.println("onTestSuccess");
}

@Override
public void onTestFailure(ITestResult iTestResult) {
    System.out.println("onTestFailure");
}

@Override
public void onTestSkipped(ITestResult iTestResult) {
    System.out.println("onTestSkipped");
}

@Override
public void onTestFailedButWithinSuccessPercentage(ITestResult iTestResult) {
    System.out.println("onTestFailedButWithinSuccessPercentage");
}

@Override
public void onStart(ITestContext iTestContext) {
    System.out.println("onTestFailedButWithinSuccessPercentage");
}

@Override
public void onFinish(ITestContext iTestContext) {
    System.out.println("onFinish");
}
}

My Base Test Class :

package stackoverflow;

import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.BeforeSuite;

public class BaseTest {
    @BeforeSuite
    public void preStep(ITestContext txt)
    {
        System.out.println("in before suite");
        System.out.println("out");
    }
    @BeforeMethod(alwaysRun=true)
    public void setUp()
    {
        System.out.println("Before Method");
    }
    @AfterMethod
    public void closeUp(ITestResult tr)
    {
        System.out.println("After Method");
    }
    @AfterSuite
    public void postStep()
    {
        System.out.println("After Suite");
    }
}

My TestNg.xml

<?xml version="1.0" encoding="UTF-8"?>
