Parallel Execution of Cucumber Scenarios using TestNG | Selenium JAVA

In this video, we are going to see that how can we run cucumber scenarios in parallel unsing TestNG.

If you have dependent scenarios in a feature file, then you wont be able to run scenarios in parallel mode.
In that case it doesn't matter whether you are using Junit or TestNG. But if you have independent scenarios in your feature file, then i would suggest you to go for TestNG dataprovider option to run the scenarios.

So create a package with the name like parallel, and placed all your files to the same package. After that write the below code in the runner class.

@Override
@DataProvider(parallel = true)
public Object[][] scenarios()
{
}

Now run your test using TestNG. You will see that all your scenarios are running in parallel mode.

**********Please comment in case of any query*************

Also please watch other videos as well.

Is there a way we can execute the scenarios in parallel using testng.xml file (similar to how we can execute feature files in parallel using parallel=true in the testng.xml file)

How to control the thread count using sure fire plug in ? Enabling parallel=true runs all the scenarios in parallel. Can we pass thread value dynamically ? Any references please.

Hi, Can you please share any git repo for the code. While doing the same i am facing lot of issues.

No need to add the classes to same package and rename the packages as parallel. (maybe earlier it needed)
Also, I tried myself without moving the classes and became successful.
I only added the below code with Maven Surefire plugin configuration

@Override
@DataProvider(parallel = true)
public Object[][] scenarios() {
return super.scenarios();
}

Failed Configuration : @BeforeClass
