PHPUnit:致命错误

PHPUnit: Fatal error Class ClassName not found

本文关键字：致命错误 PHPUnit | 更新日期: 2023-09-27

我正在尝试为CodeIgniter应用程序构建一个单元测试环境。我遵循这本书，让PHPUnit工作。

我正在测试模型中的一些代码:

    public function testPresent()
{
    $tracker = new Tracker_model();
    $tableObj = (object)array( 'type' => $this->expectedConstants['TABLE']);
    $visitsObj = (object)array( 'type' => $this->expectedConstants['VISITS']);
    $tableObj = $tracker->present($tableObj);
    $visitsObj = $tracker->present($visitsObj);
    $this->assertThat($tableObj, $this->isInstanceOf('Tracker_TablePresenter'));
    $this->assertThat($visitsObj, $this->isInstanceOf('Tracker_VisitsPresenter'));
}

测试的代码如下:

    public function present($obj)
{
    if( isset($obj->type) )
    {
        switch($obj->type)
        {
            case self::VISITS: $type = 'Visits'; break;
            case self::TABLE: 
            default: $type = 'Table'; break;
        }
        $className = 'Tracker_'.$type.'Presenter';
        $obj = new $className($obj, 'tracker');
    }
    return $obj;
}

它应该加载在文件presenters/tracker/TablePresenter.php中的类Tracker_TablePresenter。我无法解释这种机制背后的所有逻辑，因为它太长太复杂，但我知道它是有效的，因为在另一台计算机上使用完全相同的代码，它通过了测试。相反，在我的计算机上，我得到这个错误:

.......PHP Fatal error:  Class 'Tracker_TablePresenter' not found in /home/.../application/models/tracker_model.php on line 42

我在Ubuntu上工作，而另一个让代码工作的人使用的是Mac。这是我的php -v

我也尝试将php降级到5.3，因为他正在使用5.3，但没有。同样的错误。你能帮我弄明白这是怎么回事吗?

编辑:

TablePresenter.php

文件的内容
<?php
class Tracker_TablePresenter extends Presenter
{
public function values()
{
    $this->ci =& get_instance();
    if (!isset($this->values)) {
        $this->ci->load->model('value_model', 'value');
        $this->values = $this->ci->value->getManyForTracker($this->tracker->id);
    }
    return $this->values;
}
}
?>
编辑2:

我按照JoDev的建议更改了present函数中的代码，如下所示:

    public function present($obj)
{
if( isset($obj->type) )
{
    switch($obj->type)
    {
        case self::VISITS: $type = 'Visits'; break;
        case self::TABLE: 
        default: $type = 'Table'; break;
    }
    //use include, but require is to force an internal error if the file isn't founded!
    require_once('presenters/tracker/'.$type.'Presenter.php');
    $className = 'Tracker_'.$type.'Presenter';
    $obj = new $className($obj, 'tracker');
}
return $obj;
}

现在我得到这个错误:

请尝试使用:

public function present($obj)
{
    if( isset($obj->type) )
    {
        switch($obj->type)
        {
            case self::VISITS: $type = 'Visits'; break;
            case self::TABLE: 
            default: $type = 'Table'; break;
        }
        //use include, but require is to force an internal error if the file isn't founded!
        require_once('Presenters/Tracker/'.$type.'Presenter.php');
        $className = 'Tracker_'.$type.'Presenter';
        $obj = new $className($obj, 'tracker');
    }
    return $obj;
}

感谢这个测试，你将能够知道如果错误是在autoloader或其他任何地方!告诉我还有什么…

在树中调用TablePresenter的文件在哪里?

要解决这个问题，你有(在我看来)三种可能性:
-1)在服务器的include_path中添加Presenter的父目录!(要检索实际包含，使用get_include_path())
-2)确保使用好的URL包含文件
-3)使用绝对URL

我打赌这与你机器上的文件权限有关。脚本无法找到文件，因为Apache无法打开它。

听起来像是一个区分大小写的问题(@jospratik的问题)。据我所知，OSX不区分大小写。所以这是你在linux和mac/win上工作时会遇到的问题。

将文件夹名称更改为以大写字符开头，如

Presenters/Tracker/VisitsPresenter.php

对我来说似乎是一个问题与类'Tracker_TablePresenter'找不到。您是否使用了正确的名称空间?
