The conditional command is explicit about it:

"When  the  == and != operators are used, the string to the right
 of the operator is considered a pattern and matched according to
 the rules described below under Pattern Matching, as if the ext-
 glob shell option were enabled."

The `case' command; the pattern substitution, pattern removal, and
case modification word expansions; and variables like EXECIGNORE and
GLOBIGNORE also apply pattern matching to arbitrary strings.
