PhpUnit Artisan:调用explode要求参数2为字符串

我正试图用PhpUnit测试一个laravel5.1控制器，为此我创建了一个继承自TestCase的类，并使用数据库事务和而不使用中间件

在类中，我实现了setUpBeforeClass方法，该方法包含：

Artisan::call('migrate:refresh');

当我尝试运行测试时，出现以下错误：

1) JugadoresControllerTest::test_Index_trae_arreglo_de_jugadores
ErrorException: explode() expects parameter 2 to be string, array given

希望有人能帮助我

我不知道您是否发现了这一点，但我在尝试运行Laravel5.1下的phpunit测试时遇到了类似的问题。显然，我在我的global composer安装上安装了一些过时的供应商版本（由于您的错误：

/home/vagrant/.composer/vendor/illighte/support/helpers.php:390

）

我所做的只是将cd刻录到我的composer目录：

cd/home/vagrant/.composer

并运行

composer更新

这更新了我的全球作曲家，一切都如期进行。

谢谢，伙计，就我而言，我重新启动了homestead，一切都很顺利。忘记发帖了，谢谢！刚刚用你的建议解决了这个错误。
