I've started writing a new module to use in SS 3.1.x, and I'm now at the point where I'm starting to test various bits of functionality, however I'm running into a problem, when trying to test the "new" screen in my module, I'm receiving an error where it says Undefined property: MediaItem::$CloudinaryRef. Here are links to the model itself and the test results:

https://github.com/AndrewLowther/mediamanager/blob/master/core/code/models/MediaItem.php

https://travis-ci.org/AndrewLowther/mediamanager/jobs/9804419

It seems to only be on travis that this is a problem, and I've been trying to resolve it for the last day or so, with no luck.

Thanks.

Figured out what was going wrong here, exactly the same issue as on this thread http://www.silverstripe.org/data-model-questions/show/24659

The getters and setters accessing the value directly were causing it to break.
