I have a PHPUnit Mink test that is ensuring that some HTTP redirects are in place.
This is whittled down, but the test essentially looks like, where testRedirect() is fed by a @dataProvider:
class Testbase extends BrowserTestCase { public static $browsers = [ [ 'driver' => 'goutte', ], ]; public function testRedirect($from, $to) { $session = $this->getSession(); $session->visit($from); $this->assertEquals(200, $session->getDriver()->getStatusCode(), sprintf('Final destination from %s was a 200', $to)); $this->assertEquals($to, $session->getCurrentUrl(), sprintf('Redirected from %s to %s', $from, $to)); } } This works fine for the redirects that are handled on the webserver itself (eg, mod_rewrite ones). However, some of the redirects I need to check are handled by the DNS provider (I don't control this, but I think it is NetNames).
If I test the redirect with wget, it looks fine
$ wget --max-redirect=0 http://example1.com/ Resolving example1.com... A.B.C.D Connecting to example1.com|A.B.C.D|:80... connected. HTTP request sent, awaiting response... 301 Moved Permanently Location: https://example2.com/some/path?foo=bar [following] 0 redirections exceeded. However, when I dump the response from my test the headers are
Date: Thu, 06 Sep 2018 15:37:47 GMT Content-Length: 94 X-Powered-By: Servlet/2.4 JSP/2.0 and the response is
<head> <title></title> <meta name="revised" content="1.1.7"> </head> <body></body> with a 200 status code.
Do I need to explicitly set a request header? I tried
$session->setRequestHeader('Host', 'example1.com'); but that didn't help.
What can cause this?

This turned out to be a weird situation with the Host header, I think on the receiving end.
My test provider had some hostnames with uppercase characters in them, eg "http://Example1.com/". I had to update the test function to be
public function testRedirect($from, $to) { $parts = parse_url($from); $host = strtolower($parts['host']); $session = $this->getSession(); $session->setRequestHeader('Host', $host); $session->visit($from); $this->assertEquals(200, $session->getDriver()->getStatusCode(), sprintf('Final destination from %s was a 200', $to)); $this->assertEquals($to, $session->getCurrentUrl(), sprintf('Redirected from %s to %s', $from, $to)); } to force the Host header to be lowercase.
