Tests_User_Capabilities should test all capabilities for each role

[johnbillion]

The Tests_User_Capabilities unit test class only tests a sampling of capabilities for each role in the test_user_{role}() methods.

These methods should have complete coverage of all capabilities for each role.

[johnbillion]

Note that all existing capabilities should be tested for all roles, with assertTrue() and assertFalse() used accordingly.

[anubisthejackle]

Add all capabilities from Codex.

[anubisthejackle]

Patch added. Adds capabilities listed in ​the codex page. Tests for both true and false where applicable.

[johnbillion]

Thanks for the patch, anubisthejackle!

I think this can be made a little clearer, and it needs support for the differing capabilities when multisite is enabled too. I have an updated patch which I'll attach shortly.

Comprehensive unit tests for every available capability, and for all roles.

In 49604:

Build/Test Tools: Ensure user capability assertions are performed for all default roles.

The existing assertions were erroneously placed outside the iteration of all users, and therefore were only run against the last user in the list, which is the Subscriber role.

See #51344, #32394

[johnbillion]

In 49605:

Built/Test Tools: Switch to a data provider for the default user role and capability tests.

This test previously performed 1,010 assertions, and a failure in any one would prevent the other assertions from running. Using a data provider means simultaneous failures will all be reported at once.
