我正在尝试使用PHPunit来测试输出一些自定义标头的类.

问题是在我的机器上这个:

<?php

class HeadersTest extends PHPUnit_Framework_TestCase {

    public function testHeaders()
    {
        ob_start();

        header('Location: foo');
        $headers_list = headers_list();
        header_remove();

        ob_clean();

        $this->assertContains('Location: foo', $headers_list);
    }
}

甚至这个:

<?php

class HeadersTest extends PHPUnit_Framework_TestCase {

    public function testHeaders()
    {
        ob_start();

        header('Location: foo');
        header_remove();

        ob_clean();
    }
}

返回此错误:

name@host [~/test]# phpunit --verbose HeadersTest.php
