Extent Reports 3.1.5 not appending after each test run - extentreports

Question

I am use Extent Reports 3.1.5 and my reports keep getting overwritten on each test run. I have implemented to the bests of my ability the solution found on stack-overflow and various sites and no progress. I have spent 24 hours troubleshooting this issue and need help.
I even went and examined the following sites http://extentreports.com/docs/versions/3/java/#htmlreporter-features
http://extentreports.com/docs/versions/3/java/#htmlreporter-features
and check my code and still could not find the issue. If there is something i am overlooking please help me.
Again my test runs however it only writes the last test ran in my testng.xml file
This is my Base Test Class:
package test;
public class BaseTest {
//-------Page Objects----------
login_Page objBELogin;
poll_Page objCreatePoll;
survey_Page objCreateSurvey;
task_Page objCreateTaskGroup;
discussion_Page objCreateDiscussion;
userprofile_Page objUserProfile;
event_Page objectEvent;
workgroup_Page objectWorkgroup;
workroom_Page objectWorkroom;
//-----------------------------
static WebDriver driver;
static String homePage = "https://automation-ozzie.boardeffect.com/login";
ExtentReports report;
ExtentTest test;//--parent test
#BeforeClass
public void setUp() throws InterruptedException{
//--------Extent Report--------
report = ExtentFactory.getInstance();
//-----------------------------
System.setProperty("webdriver.chrome.driver","C:\\GRID\\chromedriver.exe");
ChromeOptions option = new ChromeOptions();
option.addArguments("disable-infobars");
driver = new ChromeDriver(option);
driver.manage().window().maximize();
driver.get(homePage);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
#BeforeMethod
public void register(Method method) {
String testName = method.getName();
test = report.createTest(testName);
}
#AfterMethod
public void catureStatus(ITestResult result) {
if (result.getStatus()==ITestResult.SUCCESS) {
test.log(Status.PASS,"Test Method named as : "+ result.getName()+" is passed");
}else if(result.getStatus()==ITestResult.FAILURE) {
test.log(Status.PASS,"Test Method named as : "+ result.getName()+" is FAILED");
test.log(Status.FAIL,"Test failure : "+ result.getThrowable());
}
else if(result.getStatus()==ITestResult.SKIP) {
test.log(Status.PASS,"Test Method named as : "+ result.getName()+" is skipped");
}
}
#AfterClass
public void tearDown() throws InterruptedException {
report.flush();
driver.quit();
}
}
public class ExtentFactory {
public static ExtentReports getInstance() {
ExtentHtmlReporter html = new ExtentHtmlReporter("surefire-reports//Extent.html");
html.setAppendExisting(true);
ExtentReports extent = new ExtentReports();
extent.attachReporter(html);
return extent;
}
}

You have to consider adding a unique name to report file for each run.
import java.text.SimpleDateFormat;
import java.util.Date;
public class ExtentFactory {
public static ExtentReports getInstance() {
String out = new SimpleDateFormat("yyyy-MM-dd hh-mm-ss'.html'").format(new Date());
ExtentHtmlReporter html = new ExtentHtmlReporter("surefire-reports//"+out);
ExtentReports extent = new ExtentReports();
extent.attachReporter(html);
return extent;
}
}
You will also need to move the report instance creation to #beforesuite, so that it runs only once for the entire test suite.
#BeforeSuite
public void OneTimesetUp() throws InterruptedException{
//--------Extent Report--------
report = ExtentFactory.getInstance();
//-----------------------------
}
