Codeigniter 2和codeception

Question

我安装了一个干净的CodeIgniter框架版本2。并在/tests/unit/PostTest.php中创建了phpunit测试，内容如下：

    <?php

    class PostTest extends PHPUnit_Framework_TestCase
    {
    private $CI;

    public function setUp()
    {
        $this->CI = &get_instance();
        $this->CI->load->database('testing');
    }

    public function testGetsAllPosts()
    {
        $this->CI->load->model('post');
        $posts = $this->CI->post->getAll();
        $this->assertEquals(1, count($posts));
    }
}

这是我的引导程序：http://conversal.w0p.be/tests/unit/_bootstrap.phps

当我运行codecept run unit --bedug时，我得到这样的信息:运行PostTest::testGetsAllPosts PHP致命错误:在/var/www/sites/conversal.w0p.be/tests/unit/PostTest.php的第9行调用未定义的函数get_instance() PHP堆栈跟踪: PHP 1. {main}() /usr/bin/codecept:0 PHP 2.

看起来它没有加载_bootstrap？

Answer 1

问题似乎出在这里：

$this->CI = &get_instance();

它应该是：

$this->CI =& get_instance();
