function CommentInterfaceTest::testCommentLinks

Tests comment links.

The output of comment links depends on various environment conditions:

• Various Comment module configuration settings, user registration settings, and user access permissions.
• Whether the user is authenticated or not, and whether any comments exist.

To account for all possible cases, this test creates permutations of all possible conditions and tests the expected appearance of comment links in each environment.
