I will fix up this PR to the new pattern,

[johlju]

Yep. Give me a few minutes to rebase and fix up the tests with the new pattern. 😄

[johlju]

Hmm.. the rebase removed the integration tests. :/ The files are just poof gone. Strange. I get them from the fork branch. It will take another few minutes. 😄

@PlagueHO Now it is ready. It was to early in the morning, I forgot to fetch latest changes from fork before rebasing so files disappeared 🤦‍♂ Ready for review now!

[PlagueHO]

Sweet - just in bed now, but will review tomorrow first thing!
