错误：必须通过webdriver.gecko.driver系统属性设置驱动程序可执行文件的路径

Question

I am working on an automated functional unit testing in PHP. I want to run a test on staging environment using PhpStorm and I am following this link: https://www.sitepoint.com/using-selenium-with-phpunit/. I have complete tasks up-to this code : i have visited this link but not work for me. The path to the driver executable must be set by the webdriver.gecko.driver system property

<?php

class uatTest extends PHPUnit_Extensions_Selenium2TestCase
{
    public function setUp()
    {
        $this->setHost('localhost');
        $this->setPort(4444);
        $this->setBrowserUrl('https://www.facebook.com/');

        $this->setBrowser('firefox');
    }
    public function tearDown()
    {
        $this->stop();
    }
    public function validInputsProvider()
    {
        $inputs[] = [
            [
                'email'              => 'user',
                'pass'              => 'pass'
            ]
        ];
        return $inputs;
    }
    public function testFormSubmissionWithUsername()
    {
        $this->byName('email')->value('user');
        $this->byId('loginbutton')->submit();
        $email = $this->byName('email');
        $this->assertEquals('user', $email->value());
    }
}

as my selenium server is running:

when i have run my test on phpstorm i get this error
