Parallel execution of Features is not working

[sherish2021]

Hi,

I am currently working with the Serenity-cucumber-starter repo and have added a few features which I am looking to test the parallel execution functionality for. I am following the config steps detailed here:

https://johnfergusonsmart.com/parallel-test-execution-with-cucumber-and-serenity-bdd/

However the parallel execution feature does not seem to be working, it just fires off each test and feature sequentially? I would expect with this config working as expecting it is creating multiple browser instances in parallel to decrease execution times.

Is there some additional I am missing here or a current known issue?

Parallel execution of classes via surefire or failsafe doesn't work with junit 5 - you need to use junit 4 for that.

[sherish2021]

Thanks @wakaleo for the response, much appreciated - anywhere I can source the junit4 pom config required for Serenity to get the parallel execution running?

Are there future plans to get the parallel execution working with junit5?

[wakaleo]

I'll update an example in the coming weeks. The issue is a junit thing, not a Serenity thing.

[patrykost]

hi @wakaleo, could you share any working parallel running pom example? or could you update serenity-cucumber-starter pom.xml to run features in parallel? thanks in advance! :)

[wakaleo]

It can work running JUnit 4 separate runner files. Parallel execution doesn't seem to work in JUnit 5 as yet.
