Systems testing

Description

Implemented all of the provider / manager systems tests listed in the test document.

These tests do not all pass! Some of the tested functions are broken, and others haven't been implemented yet. Use these as reference to fix bugs.

Some of these tests have a weird issue where they'll fail when run in a group, but pass when run on their own. If you're not sure why a test isn't passing, try running it specifically.
