Hi there
I have a problem with controller test cases and I think this is a
general problem. It may be that I am totally wrong, however it would be
great if someone could help me sort this out.
When dispatching multiple times within a controller test case, the
assertion about the redirection might lead to a wrong result.
In my case I have to login before I can dispatch the tested controller,
the tested action is only accessible by an authenticated and authorized
user.
In order to be able to send a form that validates, I dispatch the action
by a _GET_ request, get the _csrf_ token and dispatch the action again
with a _POST_ request - all after logging in first.
Login works and the _GET_ request of the tested action works as well, I
am able to read the csrf token from the response. I am positive that the
post request works as well (I can verify the creation of a new item in
the testing database).
The last issued request (post request) finally redirects to a specific
location. This works when doing this with the browser. If done in a
controller test case, the assertion about the location header fails with
the reason that the effective redirection is taking place to "/" instead
to the specific route.
The header with the correct location is present, that can be verified by
investiating the actual response. In fact the method
=toString()= of the headers gives a different result than accessing the
location header directly:
$headers = $this->getApplication ()->getResponse ()->getHeaders ();
...
var_dump ($headers->toString ());
// leads to:
string(41) "Location: /pres/pharmacy/edit/1
"
...
var_dump ($headers->get ('location'));
// leads to:
class Zend\Http\Header\Location#3642 (1) {
protected $uri =>
class Zend\Uri\Uri#3869 (8) {
protected $scheme =>
NULL
protected $userInfo =>
NULL
protected $host =>
NULL
protected $port =>
NULL
protected $path =>
string(1) "/"
protected $query =>
NULL
protected $fragment =>
NULL
protected $validHostTypes =>
int(31)
}
}
Now the test fails:
Failed asserting response redirects to "/pres/pharmacy/edit/1", actual
redirection is "/"
I am not sure if multiple dispatching within controller tests is
something that is not supposed to work. If this was the case, I would
need to refactor about the entire application, complicating things
heavily - I would need to modify the entire authentication stack, modify
the creation of all forms and so on - everything in order to be able to
test the application. I hope there is another answer to this...
Big thanks in advance!
