Question

I’m having trouble getting Selenium to see sites hosted on a virtual
machine. The following test causes an error, and I have no idea why:

<?php

require_once 'PHPUnit/Extensions/SeleniumTestCase.php';

class ActualTest extends PHPUnit_Extensions_SeleniumTestCase
{
    protected function setUp()
    {
        $this->setBrowser("*firefox");
        $this->setBrowserUrl("http://10.48.77.48/"); // IP of virtual machine
        $this->setHost('192.168.101.1'); // IP of my Mac
    }

    public function testGetHomePage()
    {
        $this->open("/", true);
    }
}

It returns the following error message, indicating that it couldn’t
find the virtual machine:

$ phpunit ActualTest.php
PHPUnit 3.5.6 by Sebastian Bergmann.

E

Time: 7 seconds, Memory: 6.75Mb

There was 1 error:

1) ActualTest::testGetHomePage
PHPUnit_Framework_Exception: Response from Selenium RC server for testComplete().
XHR ERROR: URL = http://10.48.77.48/ Response_Code = 404 Error_Message = Page Not Found.


/home/craiga/ombudsman/app/systemtests/ActualTest.php:16

FAILURES!
Tests: 1, Assertions: 0, Errors: 1.

I can access this site any browser anywhere on the network without any
problem, but for some reason the browser launched by Selenium can’t.
This error occurs whether I launch the test from the virtual machine
or the Mac.

I can get the following test to connect to Google without any problem:

<?php

require_once 'PHPUnit/Extensions/SeleniumTestCase.php';

class VanitySearchTest extends PHPUnit_Extensions_SeleniumTestCase
{
    protected function setUp()
    {
        $this->setBrowser("*firefox");
        $this->setBrowserUrl("http://www.google.com.au/");
        $this->setHost('192.168.101.1'); // IP of my Mac
    }

    public function testSearchForSelf()
    {
        $this->open("/");
        $this->type("q", "craig anderson");
        $this->click("btnG");
        $this->waitForPageToLoad("30000");
        try {
                $this->assertTrue($this->isTextPresent("craiga.id.au"));
        } catch (PHPUnit_Framework_AssertionFailedError $e) {
                array_push($this->verificationErrors, $e->toString());
        }
    }
}

This test, which connects to my Mac’s default page, also passes
without any problems:

<?php

require_once 'PHPUnit/Extensions/SeleniumTestCase.php';

class MacTest extends PHPUnit_Extensions_SeleniumTestCase
{
    protected function setUp()
    {
        $this->setBrowser("*firefox");
        $this->setBrowserUrl("http://192.168.101.1/");
        $this->setHost('192.168.101.1'); // IP of my Mac
    }

    public function testMacHomePage()
    {
        $this->open("/");
        try {
                $this->assertTrue($this->isTextPresent("It works!"));
        } catch (PHPUnit_Framework_AssertionFailedError $e) {
                array_push($this->verificationErrors, $e->toString());
        }
    }
}

Does anyone have any idea why this might be happening? I’m happy to
provide whatever information I can about my setup. I’m using Selenium
Server 1.0.3, and the latest phpunit from pear.

Solved. My application wasn’t responding correctly to HEAD requests. To test your application, run the following:

curl --head http://10.48.77.48/

If it returns a 404, your application probably isn’t handling HEAD requests properly.
