Parallel Testing Thread Getting Orphaned Selenium - selenium

Question

My test is executed on my VM. Chrome loads first and then IE. IE Completes the test but Chrome gets orphaned. I think this has something to do with the threads connecting with the proper browser.
I have tried many hours trying different ways of setting up Parallel testing with Selenium/TestNG and the result is the same as I described above.
My goal is for both browsers to complete the test. Can you please help me.
Please find my code below.
public class BaseTestDirectory {
// -------Reference Variables-------------
// ----- Regression Test Cases -----
LoginLogoutPage objBELogin;
HomeNavigationPage obj_navigation;
DirectoryPage obj_directory;
// -------------------------------
protected static WebDriver driver;
protected ExtentTest test;// --parent test
ExtentReports report;
ExtentTest childTest;
#BeforeClass
#Parameters(value={"browser"})
public void setUp(String browser) throws InterruptedException, MalformedURLException {
// --------Extent Report--------
if(browser.equals("Chrome")){
report = ExtentManager.getInstance();
System.setProperty("webdriver.chrome.driver", "C:\\GRID\\chromedriver.exe");
System.out.println(System.getenv("BUILD_NUMBER"));
String env = System.getProperty("BUILD_NUMBER");
if (env == null) {
driver = new RemoteWebDriver(new URL(COMPLETE_NODE_URL), OptionsManager.getChromeOptions());
driver.get(HOME_PAGE);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
} else {
driver = new ChromeDriver();
driver.get(HOME_PAGE);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
}
else if (browser.equals("IE")) {
report = ExtentManager.getInstance_IE();
System.setProperty("webdriver.ie.driver", "C:\\GRID\\IEDriverServer.exe");
System.out.println(System.getenv("BUILD_NUMBER"));
String env = System.getProperty("BUILD_NUMBER");
driver = new RemoteWebDriver(new URL(COMPLETE_NODE_URL), OptionsManager.getInternetExplorerOptions());
driver.get(HOME_PAGE);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
}

Answer 1

Initializing the WebDriver object as a Thread Local for Parallel Test Execution: When you have decided to run your selenium's tests in parallel, your Webdriver object should be thread-safe i.e. a single object can be used with multiple threads at the same time without causing problems.
public class BaseTest {
//Declare ThreadLocal Driver (ThreadLocalMap) for ThreadSafe Tests
protected static ThreadLocal<RemoteWebDriver> driver = new ThreadLocal<>();
public CapabilityFactory capabilityFactory = new CapabilityFactory();
#BeforeMethod
#Parameters(value={"browser"})
public void setup (String browser) throws MalformedURLException {
//Set Browser to ThreadLocalMap
driver.set(new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capabilityFactory.getCapabilities(browser)));
}
public WebDriver getDriver() {
//Get driver from ThreadLocalMap
return driver.get();
}
#AfterMethod
public void tearDown() {
getDriver().quit();
}
#AfterClass void terminate () {
//Remove the ThreadLocalMap element
driver.remove();
}
}

Try to design your base class in the below given example
public class WebDriverFactory {
static WebDriver create(String type) throws IllegalAccessException{
WebDriver driver;
switch(type) {
case "Firefox":
driver = new FirefoxDriver();
break;
case "Chrome":
driver = new ChromeDriver();
break;
default:
throw new IllegalAccessException();
}
return driver;
}
}
public class BaseClass extends WebDriverFactory {
public static ThreadLocal<WebDriver> dr = new ThreadLocal<WebDriver>();
#Parameters("browser")
#BeforeMethod
public void beforemethod() throws IllegalAccessException{
WebDriver driver = new WebDriverFactory().create(browser);
setWebDriver(driver);
getWebDriver().manage().window().maximize();
getWebDriver().manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
public void setWebDriver(WebDriver driver){
dr.set(driver);
}
public WebDriver getWebDriver(){
return dr.get();
}
#AfterMethod
public void aftermethod(){
getWebDriver().quit();
dr.set(null);
}
}
