I am trying to setup functional tests on my Centos Server using Selenium Web Server and Phpunit.
When I run the tests, I get an error in the command line :
PHPUnit_Extensions_Selenium2TestCase_WebDriverException:
Unable to connect to host vmdev-pando-56 on port 7055 after 45000 ms.
Firefox console output: Error: no display specified
I've been doing research for more than three days and I couldn't find a solution. I read many posts, including SOverflow. As per my understanding, everything is properly set up, and yet I am experiencing the same problem as many other people, and the solutions that work for them seem to be not working for me.
This is my setup:
- OS:
Centos 6.5 x86in command line (no GUI) - PHP:
5.6 - Phpunit:
3.7, although I also tried with5.3 - Selenium standalone web server:
2.53, downloaded from here, although I also tried with2.9 - Xvfb system:
xorg-x11-server-Xvfb - Firefox:
38.0.1, although I also tried with38.7
I also set the DISPLAY to :99 in my bash profile:
This is what I do to set up the environment:
- First, I launch the Xvfb system:
/usr/bin/Xvfb :99 -ac -screen 0 1280x1024x24 & - Then I launch the Selenium server:
/usr/bin/java -jar /usr/lib/selenium/selenium-server-standalone-2.53.0.jar & - I launch Firefox:
firefox &(although I know this is not necessary, but just in case)
All of the three processes are running in background.
At this point, I know that Firefox is operative, as well as the X buffer. I can run the command firefox http://www.stackoverflow.com & and then take an snapshot of the buffer by executing import -window root /tmp/buffer_snapshot.png, which happens to be something like this:
I of course received a warning on the terminal: Xlib: extension "RANDR" missing on display ":99", but I read countless of times that this is not a problem.
Anyway, the problem begins just now.
I've written a rather simple functional test (please notice that other tests I've written other than functional, they work just fine, so the environment in that respect seem to be properly configured):
<?php
namespace My\APP\BUNDLE\Tests\Functional\MyTest;
use PHPUnit_Extensions_Selenium2TestCase;
class HelloWorldTest extends PHPUnit_Extensions_Selenium2TestCase {
protected function setUp() {
$this->setBrowser('firefox');
$this->setHost('localhost');
$this->setPort(4444);
$this->setBrowserUrl('http://www.stackoverflow.com');
}
public function testTitle() {
$this->url('/');
$this->assertEquals("1", "1");
}
}
And when I run the test by issuing phpunit HelloWorldTest.php, I get the following error:
PHPUnit_Extensions_Selenium2TestCase_WebDriverException:
Unable to connect to host vmdev-pando-56 on port 7055
after 45000 ms. Firefox console output:
Error: no display specified
Checking the log file generated by selenium, I found the following (interesting) lines:
21:55:46.135 INFO - Creating a new session for Capabilities [{browserName=firefox}]

java.util.concurrent.ExecutionException:

(The file contains the complete stack trace dump, and the original message of no display specified)
No errors in the Xvfb log file.
At this point I have no clue of what I am doing wrong.
Can anyone help?
Thanks a lot
