Parallel test execution in Selenium Java + TestNG

Всем привет!
Занимаюсь автоматизацией несколько месяцев, дома на досуге пишу свой фреймворк в нерабочее время. У меня изначально инстанс WebDriver’a был статическим, т.к. я запускал каждый тест в одиночку, когда писал его и не было нужды тогда заниматься параллелизацией. Сейчас решил это исправить, уже много разных вариантов пробовал, но всеравно натыкаюсь на NPE во время параллельного запуска нескольких тестов через testng.xml.

Вот мои сниппеты:

testng.xml

<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="FitSuite" parallel="methods">

  <listeners>
    <listener class-name="resources.Listeners"/>
  </listeners>

  <test name="HomePageTest">
    <classes>
      <class name="selenium.tests.HomePageTest"/>
      <class name="selenium.tests.LoginPageTest"/>
      <class name="selenium.tests.MyClassesTest"/>
</suite>

TestBase.class

public class TestBase {
  public  /*static*/ WebDriver driver;
  protected Properties properties;
  public Logger log = LogManager.getLogger(TestBase.class.getName());
  public static String propertiesFilePath =
    System.getProperty("user.dir") + "//src//main//java//resources//TestProperties.properties";

  public WebDriver initializeDriver() {

    try {
      properties = new Properties();
      properties.load(new FileInputStream(propertiesFilePath));
      String browserName = properties.getProperty("browser");

      if (browserName.equalsIgnoreCase("chrome")) {
        System.setProperty("webdriver.chrome.driver",
          System.getProperty("user.dir") + "//src//main//java//resources//chromedriver");
        driver = new ChromeDriver();
      }
      else if (browserName.equalsIgnoreCase("chrome-headless")) {
        System.setProperty("webdriver.chrome.driver",
          System.getProperty("user.dir") + "//src//main//java//resources//chromedriver");

        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--headless");
        // chromeOptions.setHeadless(true); -- this is the same as above.
        driver = new ChromeDriver(chromeOptions);
      }
      else if (browserName.equalsIgnoreCase("firefox")) {
        System.setProperty("webdriver.gecko.driver",
          System.getProperty("user.dir") + "//src//main//java//resources//geckodriver");
        driver = new FirefoxDriver();
      }
      else driver = new SafariDriver();

    } catch (IOException e) {
      e.printStackTrace();
      log.fatal("Driver initialization has been crashed");
    }

    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(7, TimeUnit.SECONDS);
    log.info("Driver has been initialized successfully");

    return driver;

    driver.manage().deleteAllCookies();
    driver.quit();
    driver = null;
    log.info("Driver session has been ended successfully");
  }

  public void takeScreenshot(String testResult) {
    try {
      File screenshotFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
      FileUtils.copyFile(screenshotFile, new File(
        System.getProperty("user.dir") + "//ScreenshotsFailure//"
        + testResult + "__" + "failure.png"));

      log.info("Screenshot of " + testResult + "'s failure has been created successfully");
    } catch (IOException e) {
      e.printStackTrace();

Буду очень признателен за советы более опытных коллег. Спасибо большое наперед
