CodeIgniter 上的 SimpleTester 失败，并显示“找不到类‘GroupTest’”

Question

我正在尝试在新的 CodeIgniter 应用程序上进行全新安装 SimpleTester，按照此处的说明进行操作：http://codeigniter.com/wiki/SimpleTester_-_Unit_testing_library

一切都很好，直到第 6 步，当我将“simplester”添加到自动加载的库列表中时。一旦我这样做，访问任何页面都会导致：

致命错误：在中找不到类“GroupTest” /path/to/app/application/libraries/simplester.php 在第 84 行

浏览 GroupTest 的代码，我只看到它在 cmets 和一个自述文件中被引用，其中说明了以下内容：

GroupTest 已重命名为 TestSuite（见下文）。 它在 1.1 中被完全删除，有利于这一点 名字。

我尝试修改第 84 行以将 GroupTest 替换为 TestSuite，但随后出现以下错误：

致命错误：调用未定义的方法 TestSuite::addTestFile() in /home/path/to/app/application/libraries/simplester.php 在第 96 行

这是他们的错误吗？有人见过这个吗？

Answer 1

我遇到了同样的问题。 GroupTest 类可以在 SimpleTest 1.0.1 版本的 test_case.php 中找到： http://sourceforge.net/projects/simpletest/files/simpletest/simpletest_1.0.1/

不幸的是，简单地将 v1.0.1 插入到库文件夹中并不能解决世界上所有的问题。我不再收到“致命错误：找不到类‘GroupTest’...”错误，但我确实遇到了分段错误并且我的网站不再工作。

我曾短暂尝试追查问题，但无济于事。

注意：我也回复了CodeIgniter Wiki page containing the same question。

Answer 2

我在当前项目中遇到了同样的问题，发现问题是 GroupTest 被替换为 TestSuite，它的工作方式略有不同。

这是我使用的库代码：

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

$libraryDir = APPPATH . 'libraries/simpletest';

if(!is_dir($libraryDir))
    exit("Simpletest must be located in \"$libraryDir\"");

require_once $libraryDir . '/unit_tester.php';
require_once $libraryDir . '/mock_objects.php';
require_once $libraryDir . '/collector.php';

class SimpleTester
{
    /**
    * What reporter should be used for display.
    * Could be either HtmlReporter, SmallReporter, MinimalReporter or ShowPasses.
    */
    public $Reporter = 'MinimalReporter';

    private $testDir;
    private $testTitle;
    private $fileExtension;

    public function __construct($params = false)
    {
        $ci =& get_instance();

        $ci->config->load('simpletester');

        if($params == false) {
            $params['runFromIPs'] = $ci->config->item('runFromIPs');
            $params['testDir'] = $ci->config->item('testDir');
            $params['fileExtension'] = $ci->config->item('fileExtension');
            $params['autorun'] = $ci->config->item('autorun');
            $params['reporter'] = $ci->config->item('reporter');
            $params['testTitle'] = $ci->config->item('testTitle');
        }

        if(isset($params['runFromIPs']) && strpos($params['runFromIPs'], $ci->input->server('SERVER_ADDR') === FALSE))
        {
            // Tests won't be run automatically from this IP.
            $params['autorun'] = FALSE;
        }

        // Check if call was an AJAX call. No point in running test
        // if not seen and may break the call.
        $header = 'CONTENT_TYPE';
        if(!empty($_SERVER[$header])) {
            // @todo Content types could be placed in config.
            $ajaxContentTypes = array('application/x-www-form-urlencoded', 'multipart/form-data');
            foreach ($ajaxContentTypes as $ajaxContentType) {
                if(false !== stripos($_SERVER[$header], $ajaxContentType))
                {
                    $params['autorun'] = FALSE;
                    break;
                }
            }
        }

        $this->testDir = $params['testDir'];
        $this->testTitle = $params['testTitle'];
        $this->fileExtension = $params['fileExtension'];

        if(isset($params['reporter']))
            $this->Reporter = $params['reporter'];

        if($params['autorun'] == TRUE)
            echo $this->Run();
    }

        $oldcookie = $_COOKIE;

        $test_suite = new TestSuite($this->testTitle);

        // Add files in tests_dir
        if(is_dir($this->testDir))
        {
            if($dh = opendir($this->testDir))
            {
                while(($file = readdir($dh)) !== FALSE)
                {
                    // Test if file ends with php, then include it.
                    if(substr($file, -(strlen($this->fileExtension)+1)) == '.' . $this->fileExtension)
                    {
                        $test_suite->addFile($this->testDir . "/$file");
                    }
                }
                closedir($dh);
            }
        }

        // Start the tests
        ob_start();
        $test_suite->run(new $this->Reporter);
        $output_buffer = ob_get_clean();

        // Restore superglobals
        if(isset($oldsession)) $_SESSION = $oldsession;
        $_REQUEST = $oldrequest;

        $_GET = $oldget;
        $_FILES = $oldfiles;
        $_COOKIE = $oldcookie;

        return $output_buffer;
    }
}

        print "<span class=\"pass\">Pass</span>: ";

}

对我来说效果很好，但我还没有测试所有不同的记者。但是默认的效果很好。

这就是我使用它的方式：

$this->load->library('simpletester');
echo $this->simpletester->Run();

我的配置文件是：

$config['testDir'] = APPPATH . 'tests';
$config['runFromIPs'] = '127.0.0.1';
$config['reporter'] = 'HtmlReporter';
$config['autorun'] = false;
$config['fileExtension'] = 'php';
$config['testTitle'] = 'My Unit Tests';
