如何设置cucumber testng框架并行执行的线程数？

Question

I would like to limit the parallel execution thread count in cucumber testng framework. Now by default 10 threads (browsers) are getting started.

I am using cucumber-java and cucumber-testng version 7.8.0 and maven-surefire plugin version 3.0.0-M6. And testng version is 7.5

I tried setting thread configurations under maven-surefire-plugin but the same didn't work. Please help me to set the threadcount somewhere so that I can limit the no. of parallel executions in cucumber framework.

I have added the below code in my testrunner file to support parallel execution.

import org.testng.annotations.DataProvider;
 
import io.cucumber.testng.AbstractTestNGCucumberTests;
import io.cucumber.testng.CucumberOptions;
 
@CucumberOptions(tags = "", features = "src/test/resources/features", glue = ""src/test/resources/teststepDefinitions")
 
public class CucumberRunnerTests extends AbstractTestNGCucumberTests {
 
    @Override
    @DataProvider(parallel = true)
    public Object[][] scenarios() {
        return super.scenarios();
    }
 
}```

You have to set dataproviderthreadcount . You can do this through surefire.
