ElementClickInterceptedException on cucumber parallel AbstractTestNGCucumberTests - selenium-webdriver

Question

I have parallel test setup in cucumber 6.9.1 using AbstractTestNGCucumberTests and then directing the test to a grid using RemoteWebDriver
#Override
#DataProvider(parallel = true)
public Object[][] scenarios() {
return super.scenarios();
}
}
and creating RemoteWebDriver like below
String hubURL = "http://192.168.1.7:65299/wd/hub";
System.setProperty("webdriver.gecko.driver", "/Users/../../geckodriver");
FirefoxProfile profile = new FirefoxProfile();
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
capabilities.setPlatform(Platform.ANY);
FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
return driver = new RemoteWebDriver(new URL(hubURL),options);
It opens two instances of firefox , and they overlap each other and I keep getting
org.openqa.selenium.ElementClickInterceptedException: Element <button class="btn btn-link pull-right" on one or the other instance of firefox .
I have tried several solutions mentioned in many questions but none of them seems to help in my scenario
I tried below solutions
global.wait.until(ExpectedConditions.visibilityOf(PageObjects.AddUser));
global.jsExecutor.executeScript("arguments[0].click();", PageObjects.AddUser);
PageObjects.AddUser.sendKeys(Keys.ENTER);
Actions builder = new Actions(global.driver);
Action clickElement = (Action) builder.click(PageObjects.AddUser);
clickElement.perform();
global.wait.until(ExpectedConditions.invisibilityOfElementLocated((By) PageObjects.allDom));
I am running test on FF 77.0 and Mac OS (catalina)
How do I resolve this?
EDIT. To include ThreadLocal change
public class FirefoxManager extends DriverManager{
private final ThreadLocal<RemoteWebDriver> driver = new ThreadLocal<>();
#Override
protected RemoteWebDriver createDriver() throws MalformedURLException , IOException {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
System.out.println("hubport from sys prop var.."+System.getProperty("hub.port"));
String hubURL = "http://192.168.1.7:65299/wd/hub";
System.setProperty("webdriver.gecko.driver", "/Users/amit/Desktop/amit/projects/misc/geckodriver");
FirefoxProfile profile = new FirefoxProfile();
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
capabilities.setPlatform(Platform.ANY);
FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
driver.set(new RemoteWebDriver(new URL(hubURL),options));
return driver.get();
}

Answer 1

You will need to use ThreadLocal since WebDriver is not ThreadSafe.
copied code, but idea is same
protected ThreadLocal<WebDriver> wbdriver = new ThreadLocal<WebDriver>();
String url = "https://google.com";
wbdriver.set(new ChromeDriver(options));
wbdriver.get().manage().window().maximize();
wbdriver.get().get(url);

I achieved cucumber parallelism using courgette-jvm . It worked out of the box and run parallel test at scenario level
Simply inlclude similar runner class in cucumber. My tests are further using RemoteWebdriver to open multiple instances on selenium grid. Make sure grid is up and running and node is registered to the grid.
import courgette.api.CourgetteOptions;
import courgette.api.CourgetteRunLevel;
import courgette.api.CucumberOptions;
import courgette.api.testng.TestNGCourgette;
import io.cucumber.testng.AbstractTestNGCucumberTests;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
#Test
#CourgetteOptions(
threads = 10,
runLevel = CourgetteRunLevel.SCENARIO,
rerunFailedScenarios = true,
rerunAttempts = 1,
showTestOutput = true,
reportTitle = "Courgette-JVM Example",
reportTargetDir = "build",
environmentInfo = "browser=chrome; git_branch=master",
cucumberOptions = #CucumberOptions(
features = "src/test/resources/com/test/",
glue = "com.test.stepdefs",
publish = true,
plugin = {
"pretty",
"json:target/cucumber-report/cucumber.json",
"html:target/cucumber-report/cucumber.html"}
))
class AcceptanceIT extends TestNGCourgette {
}
RemoteWebdriver config is
protected RemoteWebDriver createDriver() throws MalformedURLException , IOException {
Properties properties = new Properties();
ClassLoader loader = Thread.currentThread().getContextClassLoader();
String hubURL = "http://192.168.1.7:65299/wd/hub";
System.setProperty("webdriver.gecko.driver", "/Users/amit/Desktop/amit/projects/misc/geckodriver");
FirefoxProfile profile = new FirefoxProfile();
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
capabilities.setPlatform(Platform.ANY);
FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
driver.set(new RemoteWebDriver(new URL(hubURL),options));
return driver.get();
}
