Selenium服务器 – PHPUnit无法连接

我使用的是最新的Selenium stand服务器2.42.2.当我运行服务器时,它显示：

root@test:/home/jakub# java -jar /usr/local/bin/selenium-server-standalone-2.42.2.jar

似乎Selenium服务器正常运行.但是当我尝试在PHP中运行简单测试时,使用PHPUnit,它说它无法连接到Selenium服务器.

root@test:/home/jakub# /usr/local/bin/phpunit --verbose sel.php
PHPUnit 4.1.3 by Sebastian Bergmann.

SS

Time: 73 ms,Memory: 3.25Mb

There were 2 skipped tests:

1) loginTest::testLoginTrue
The Selenium Server is not active on host http://test.jacon.cz at port 4444.

2) loginTest::testLoginFalse
The Selenium Server is not active on host http://test.jacon.cz at port 4444.

OK,but incomplete,skipped,or risky tests!
Tests: 2,Assertions: 0,Skipped: 2.

我通过netstat -apn检查了如果Selenium服务器正在侦听端口4444并且它正在侦听,则为grep 4444.有人知道如何解决这个问题吗？我用Google搜索,但没有任何结果.

顺便说一下.这是php中测试的代码：

<?php
class loginTest extends PHPUnit_Extensions_Selenium2TestCase
{
protected $captureScreenshotsOnFailure = TRUE;
protected $screenshotsPath = '';
    protected $screenshotsUrl = '';

protected function SetUp()
  {
  $this->setBrowser('chrome');
  $this->setBrowserUrl('http://test.jacon.cz/');
  //$this->setPort(4444);
  //$this->setTimeout(2);
  $this->setHost("http://test.jacon.cz");
}

public function testLoginTrue()
  {
      $this->url('/sms');
  $this->byName('username')->value('Kristyna');
  $this->byName('password')->value('*****');
  $this->byCssSelector('form')->submit();
      $url = $this->url();
  $this->assertEquals('Statistics',$this->title(),'P?ihlá?ení neproběhlo');
  $this->assertStringEndsWith('sms/',$this->url(),'P?ihlá?ení neproběhlo');
  }

     public function testLoginFalse()
  {
  $this->url('/sms');
  $this->byName('username')->value('abcdefgh');
  $this->byName('password')->value('123456');
  $this->byCssSelector('form')->submit();
      $url = $this->title();
  $this->assertEquals('Login to SM','P?ihlá?ení proběhlo');
  }
}
?>

希望你能帮忙.谢谢.
