[Johnsonchan105]

• Added interceptors to ensure admin and instructor roles are updated properly
• Created and implemented tests for interceptors to ensure it is properly working
• Modified MockCurrentUserServiceImpl to use currentUserMock instead of currentUser Closes #24 Closes #12 Deployed at: https://organic-qa.dokku-05.cs.ucsb.edu

Fixed the issue of the 400 error by changing the parameter name in User Controller toggleAdmin and toggleInstructor from "Github Id" to "id". It should work now when toggling.

Wanted to do a more thorough code review to ensure this is all working.

Review: Running locally first. Pulled branch, ran npm install, server and frontend started correctly! Checked my user, admin=true, instructor=false:

Ran toggleInstructor:

Ran toggleAdmin:

Ran toggleAdmin again to check that second toggle works:

Tested on dokku organic-qa too. Looks like it works, checked GET /api/admin/users too and it updated my instructor status to true.

mvn test successful

jacoco looks like full coverage

LGTM :)
