How to run cucumber feature files in parallel ?

[80Vikram]

Hi All,

I need to run cucumber feature files in parallel mode

For junit test cases had used @RunWith(SerenityRunner.class) and maven-surefire-plugin to run in parallel.


In case of cucumber feature file have used @RunWith(CucumberWithSerenity.class) but not sure how to run these in parallel ?

Thanks in advance.

Vikram

You can do the same thing to run the Cucumber test runners in parallel. Cucumber has no support for running the individual feature files or scenarios in parallel.

Hi John,

Thanks for clarification  , maven-surefire-plugin failed for me as I was using   skipITs flag and it was causing to skip all the test cases

Just now I found about  cucumber-jvm-parallel-plugin & reading about it.

Have you tried using it earlier; any benefits compared to surefire plugin and is it supported with Serenity ?

Regards,
Vikram

Unfortunately the cucumber-jvm-parallel-plugin won’t work because it will not generate classes that use the Serenity Cucumber runner.

Here is my pom.xml portion which does the magic in running parallel on single box and as well with Grid setup + Docker
