Symfony2 Test Controller with Login and Form Submission.

For this test with phpunit we are going to login in, then browse to the client edit form, fill in some values and redirect, then verify that  the record is updated with the crawler by filtering  values in  the redirected list page.

This sample works when using the Symfony2 Form object, otherwise values are null when the form is submitted. There is a work around to pass values when submitting a standard form, but it is un ugly one just hard code the post values this way:

$_POST['name']='foo';

But as I say it's un ugly one, I haven't yet found a better way.

Then, to login an user we need to pass an user object as the first parameter to the UsernamePasswordToken function, and we'll be using the entity repository to find the user.

For debugging purpose you can check client reponse like this:

var_dump($this->client->getResponse());

This will give you useful information to correct things.
