IOSDrive becomes null and Appium TestNG tests restarts the app in between - automated-tests

Question

I am facing issues with appium test groups. I have written multiple test cases for my app and running different sets at a time.
Basically, my test flow is: Login with Google => Input Password => Logout
Then for another set same flow with Login with Facebook.
Following is the code is written in AppiumTest.java file
#Test
public class AppiumTest {
IOSDriver<MobileElement> driver = null;
public DesiredCapabilities capabilitiesForDevice(String deviceCode) {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "iOS");
capabilities.setCapability("udid", "SOME_VALID_UDID"); // 7+
capabilities.setCapability("platformVersion", "10.3.3");
capabilities.setCapability("app", "PACKAGE_PATH");
capabilities.setCapability("noReset", false);
capabilities.setCapability("showXcodeLog", true);
capabilities.setCapability("clearSystemFiles", false);
...
return capabilities;
}
#BeforeSuite(groups = {"google"}) // Removing suite also does not make any effect
public void setup() throws MalformedURLException {
System.out.print("Setting up driver.\n");
DesiredCapabilities capabilities = capabilitiesForDevice("iPhone5s");
String url = "http://0.0.0.0:4723/wd/hub";
driver = new IOSDriver<MobileElement>(new URL(url), capabilities);
}
#AfterSuite(groups = {"facebook"})
// Removing suite also does not make any effect
// Between 2 tests execution this method is not being called
public void tearDown() {
System.out.println("AfterSuite ... QUITTING DRIVER...");
driver.quit();
}
public MobileElement getElementByName(String name) {
try {
MobileElement theElement = (MobileElement) (new WebDriverWait(driver, 30))
.until(ExpectedConditions.visibilityOfElementLocated(By.name(name)));
return theElement;
} catch (Exception e) {
// e.printStackTrace();
}
return null;
}
public MobileElement getElementByXPath(String xpath) {
try {
MobileElement theElement = (MobileElement) (new WebDriverWait(driver, 30))
.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath)));
return theElement;
} catch (Exception e) {
// e.printStackTrace();
}
return null;
}
#Test(groups = {"google"}, priority = 1)

// e.printStackTrace();

}
printLog("driver = " + driver);
printLog("\nLoading is null and not logged in.." + System.currentTimeMillis());
String googleIcon = "icon google";
MobileElement gLoginElement = getElementByName(googleIcon);

Testng.xml example
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
<test name="TestGoogle">
<groups>
<run>
<include name="google" />
</run>
</groups>
<classes>
<class name="login.googleLogin.AppiumTest" />
</classes>
</test> <!-- Test -->
<test name="TestFB">
<groups>
<run>
<include name="facebook" />
</run>
</groups>
<classes>
<class name="login.googleLogin.AppiumTest" />
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
When I right click on testng.xml and run the test as TestNG Suite, the app gets restarted when the first test "TestGoogle" is completed and there after a 5-10 seconds restarts, the app continues running and executes pending test cases for "TestFacebook".
When I combine Facebook and Google, test cases for Google/Facebook are not executed.
<run>
<include name="google" />
<include name="facebook" />
</run>
Please give me hint of how to solve the issue.
