窗口上的laravel 4单元测试一直给出错误

Question

我开箱即可安装Laravel 4。我使用PHP 5.5运行Windows 8 64位，通过XAMPP运行Apache 2.2。

当我运行phpunit时，我会看到标准的laravel错误页面Whoops, looks like something went wrong.，就在它上方，我看到PHPUnit 3.8-dev by Sebastian Bergmann. Configuration read from C:\project\phpunit.xml The Xdebug extension is not loaded. No code coverage will be generated.

如果我删除了文件app/tests/ExampleTest.php，那么phpunit似乎可以正常工作，而我

   */
  public function testBasicExample()
  {
    $crawler = $this->client->request('GET', '/');
    $this->assertTrue($this->client->getResponse()->isOk());
  }

}

    $unitTesting = true;

    $testEnvironment = 'testing';

    return require __DIR__.'/../../bootstrap/start.php';
  }
