PHPUnit:数据提供者问题

Question

以下测试有什么问题:

<?php

class TestSomething extends PHPUnit_Framework_TestCase
{
    /**
     * @dataProvider provider
     */
    public function testSomething($array, $expectedResult)
    {
        $this->assertEquals($array, $expectedResult);
    }

    public function provider()
    {
        return array(
            array(array(), array()),
        );
    }
}

?>

错误信息:

$phpunit index.php

我也遇到了同样的事情，我正在使用 __construct() 方法来设置内部变量。

我需要做的是有一个 function setUp() {} 会发生这种情况。

我刚刚再次遇到这个问题 - 但这次的问题是评论 - 我曾经使用过:

/*
 * @dataProvider ....
 */

但是注释必须以/**开头才能被识别。
