TestNG를 통해 테스트를 실행하는 동안 Null 포인터 예외 발생

CSV 리더를 사용하여 DataProvider를 사용하는 테스트 기능에서 데이터를 가져오고이 데이터를 사용하고 있습니다.

TestNG Method

@Test(dataProvider = "regCSVData", dataProviderClass = LoginData.class)
public void testLoginUsingCSVFile(LoginData loginData){
    driver.get(appURL);
    Login login = PageFactory.initElements(driver, Login.class);
    login.loginToFwbm(loginData);
}

LoginData Class

@DataProvider(name = "regCSVData")
public static Object[][] getCSVData() throws IOException {
    CSVReader csvReader = new CSVReader(new FileReader(
            LoginData.class.getResource("/regdata.csv").getPath()));
    List<String[]>dataList = csvReader.readAll();
    Object[][]data = new Object[dataList.size()][1];
    List<LoginData> logList = new ArrayList<LoginData>();
    for (String[] strArray:dataList){
        LoginData loginData = new LoginData();
        loginData.setUserName(strArray[0].trim());
        loginData.setPassword(strArray[1].trim());
        logList.add(loginData);
    }
    for (int i=0; i<data.length;i++){
        for(int j=0;j<data[i].length;j++){
            data[i][j] = logList.get(i);
        }
    }
    csvReader.close();
    return data;
}
