ZF-4197: is-string Typo in Zend_Controller_Response_HttpTestCase

Description

In line 69, version 1.6.0 there is small typo in Zend_Controller_Response_HttpTestCase. There's unwanted is-string. It should be replaced with is_string.

Comments

Solved in SVN r11245. I correct is-string() to is_string() line 97.
