+OpenSSL::Test::Simple - a few very simple test functions
+
+=head1 SYNOPSIS
+
+  use OpenSSL::Test::Simple;
+
+  simple_test("my_test_name", "des", "destest");
+
+=head1 DESCRIPTION
+
+Sometimes, the functions in L<OpenSSL::Test> are quite tedious for some
+repetitive tasks.  This module provides functions to make life easier.
+You could call them hacks if you wish.
