Were unit tests breaking because the video used for tests changed it's description?

[brandongalbraith]

Unit tests tested for that output we've removed from the description. Had to update the tests to reflect the change to description output.

Does the unit tests require the item on IA to be writable by the scripts IA login?

If not, consider using the first video uploaded to Youtube: "A Day At The Zoo".

Note: I own this item.

[brandongalbraith]

Unit tests don't attempt to write to IA, so the item doesn't need to be writable.

Unit tests don't attempt to write to IA, so the item doesn't need to be writable.

Try this video instead as a unit test example. It has no description and will likely never ever change. Yes, this is the first thing ever uploaded publicly to the site.

Tested, LGTM, merging it up. Revert if any unexpected regressions occur tests don't pick up.

I'll cut a new version on or before the 1st. Thanks, Brandon.
