 There are three failures with WPTestUserCapabilities

 {{{
 1) WPTestUserCapabilities::test_role_add_cap
 Failed asserting that false is true.

 wp-testcase/test_user_capabilities.php:267

 2) WPTestUserCapabilities::test_role_remove_cap
 Failed asserting that true is false.

 wp-testcase/test_user_capabilities.php:308

 3) WPTestUserCapabilities::test_user_remove_all_caps
 Failed asserting that '' is null.

 wp-testcase/test_user_capabilities.php:445
 }}}

 Failure 1 and 2 can be fixed by a change in `_flush_roles`.  The original
 code was commented out in r199 because of a fatal error.  The patch works
 now, though.

 Failure 3 can be fixed by changing the assertion from `assertNull` to
 `assertEmpty`.  This was changed with WP #15458.
