Hi @dmikusa-pivotal ,
I have opened the PR in January and am still waiting for the contribution to be accepted in the repository. I would like to ask what else do I have to do for this PR the be accepted?

Hi, sorry for the delay. I took a quick glance and the main thing that jumps out is that there do not appear to be any integration tests. Those would be required before I can merge anything.

It does require full admin access to a CF installation. If you do not have access to one, you can run one locally using bosh-deployment & cf-deployment & Virtualbox.

1. See Install Section to install Bosh.
2. Follow the deployment guide to get CF installed. I think you can skip to step 4, since you're installing locally. Definitely read this section before you get started though. It has some info for running locally.

Before you start the tests, I would recommend taking a snapshot of the VMs in the environment. That way you can quickly restore back to the initial state (tests should clean up after themselves, but this gives you another way to refresh your env).

If you are unable to do that or unable to write the integration tests, I can write them but I cannot promise priority to that work so it will be much quicker to merge this PR if you are able to provide them. Thanks

Hi @dmikusa-pivotal,
I wrote some integration tests. Could you verify them?

I ran the unit & integration tests for this, and they passed. I'm going to merge this. Thanks for the contribution!
