Acceptance Criteria:

Build a script that can test Gateway downloads and TDS downloads.
Exercise all our file download APIs and end user URLs.
Test OpenID workflow with TDS downloads.
Test range requests.
Automate testing if possible.

Use Cases to Test... All cases need to test both a normal download and a range request download.

Gateway
- Download without authentication/authorization needed (E.g.: ncl file)

Authorization Failures
- Attempt to download a file that requires authentication without being authenticated.

This dataset only requires authentication (being logged in), but not authorization.
