Hello, I am curious if my changes in response to the review satisfy the requirements. I would love to hear what you think and if it can be merged to the main branch

@hanszt Sorry for the delay! I think this would be a very useful change.

[hanszt]

No worries. I can imagine you are busy. I'm glad you think it is a good improvement.

[marcphilipp]

@hanszt Just a quick update. I intend to include your work in a focused effort to improve Kotlin support as part of #4014 early next year. I probably won't get to it before then.

@marcphilipp Thanks for the update. Congratz on the investment of Sovereign Tech Fund in Junit5 by the way! 🎉

@hanszt I pushed a few commits of my own. Do you have time to take a look?

[marcphilipp]

I went ahead with the merge. Feedback is still welcome, though!

[hanszt]

Hi @marcphilipp ,

Nice that the pull request is merged!

Your commits and polishing of the implementation looks good!

I would really appreciate it if I could be added to the junit5 contributors list.

And maybe also add the Github achievement batch that a pull request has been merged? Or is that something that Github decides?

Thanks in advance!

Looking forward to using it in my projects and our Kotlin codebase at Drillster!

Sure thing! We list all first-time contributors as part of the release description on GitHub. So, just a little longer! 🙂

Thanks again for your contribution! 🙏
