Hi @sneal @ckganesan

A gentle reminder to get this PR reviewed🙂

Thanks

Overall I like this, we can continue to refine this functionality as needed. I just have one very minor comment around the ToString().

Can you think how we can add tests for this? I don't think we need to add them now before merging this, but it would good to start thinking how we can ensure we don't break this in the future. This is probably getting into the realm of too complex to test without using an integration test against a real running CF deployment or a more fully featured CF API simulator.

We generally prefer to use go-vcr in these kind of usecases where

• Manually mocking all api endpoints is really tough
• Having an integration test only justifies the complexity
• We don't have a landscape dedicatedly just to run CI

I feel this might be nice to be added as a future scope here.

I like the go-vcr suggestion I'll have to take a look at it.
