Hi everybody.
I am looking for some advice on how to test RESTful controllers
exchanging JSON data (I'm using $this->request->input() on all
requests methods to fetch data coming from clients). Here is the test
I started to write:
<?php
class UsersControllerTest extends ControllerTestCase {
public $fixtures = array('app.user');
public function testViewJson() {
$data = json_encode(array(
'id' => 1
));
$result = $this->testAction(
'/users.json',
array('data' => $data, 'method' => 'GET')
);
debug($result);
}
}
If I run the test, I'm getting the following error:
Fatal error: Cannot unset string offsets in

and if I comment the line raising the error (which tries unset
'/users.json' from $query), even if the test goes on with no problems,
inside the Controller $this->request->input() seems to be emtpy.
Should I have to fill a bug request for this error?
Finally, inside ``testAction`` documentation it seems possible to set
data for GET and POST requests only: is this true? If so, how can I
prefil ``php://input`` with data enabling my RESTful controller to
run?
Thank you in advance,
Matteo
