Laravel Testing Redirect::back()

Hello guys, sometimes in your functional test you need to test a redirect, this is pretty easy to test except for the Laravel Redirect::back() method. I’ve found out that this is hard to test and the only solution to solve the problem is to fake a HTTP_REFERRER value. But keep in mind that in general the best approach is to don’t use many Redirect::back() and instead use the redirect to a certain route, in fact is much more clearer from the test perspective to assert a redirect to a given route instead of a fake one. Anyways here’s the solution:

<?php

public function testRedirect(){

$fake_url = "/fake";
$this->call('GET', '/url, [], [], ['HTTP_REFERER' => $fake_url]);

$this->assertRedirectedTo($fake_url);
}

Enjoy!
