Laravel测试未定义的方法

我尝试在laravel中编写测试,但我甚至无法运行示例测试,bcs我得到错误:

? phpunit
PHP Fatal error:  Uncaught Error: Call to undefined method PHPUnit_Util_Configuration::getTestdoxGroupConfiguration() in E:\www\ikcms\vendor\phpunit\phpunit\src\TextUI\TestRunner.php:1042

当然,它发生在下载laravel之后.

Laravel版本:5.3 PHPUnit:5.0
