how pass querystring testaction cakephp 1.2?

in cakephp putting querystring url doesn't means automatically parsed separate customarily controller directly invoked.

for example:

$this->testaction('/testing/post?company=utcompany', array('return' => 'vars')) ;

will outcome in:

[url] => /testing/post?company=utcompany

while invoking url directly around web browser law in:

[url] => array
    (
        [url] => testing/post
        [company] => utcompany
    )

without modifying cakephp source, there proceed have querystring separate controlling section tests?
