Cucumber 6 + JUnit 5 + Spring Parallel Scenarios Execution

Question

I've been reading a lot of documentations, posts, articles and it's said that out-of-box solution to run scenarios in a single feature file in parallel is impossible . We can use maven-surefire-plugin to run in parallel different feature files, but not scenarios.

For example there is a feature file with scenarios:

Feature: Parallel Scenarios

    Scenario: First
        ...

    Scenario: Second
        ...

    Scenario: Third
        ...

And I'd like to run all there scenarios concurrently in separated threads.

How can I achieve this?

Answer 1

I am using testNG with courgette-jvm to run parallel tests at scenario level. Here is runner file

import courgette.api.CourgetteOptions;
import courgette.api.CourgetteRunLevel;
import courgette.api.CucumberOptions;
import courgette.api.testng.TestNGCourgette;
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 {
}

and then use regular webdriver config, I use RemoteWebDriver

  protected RemoteWebDriver createDriver() throws MalformedURLException {
     //wherever grid hub is pointing. it should work without grid too
    String hubURL = "http://localhost:xxxx/wd/hub";

         ChromeOptions options = new ChromeOptions();
         DesiredCapabilities capabilities = DesiredCapabilities.chrome();
         capabilities.setCapability(ChromeOptions.CAPABILITY, options);
         return (RemoteWebDriver) (driver = new RemoteWebDriver(new URL(hubURL), capabilities));
        
    }

     public RemoteWebDriver getDriver() throws MalformedURLException {
           if (driver == null) {
                         this.createDriver();
           }
            return (RemoteWebDriver) driver;
    }
