我试图让 PCOV 与在带有 XAMPP 的 Windows 机器上的 PHP 7.4.13 上运行的 PHP 应用程序 (Drupal) 一起工作。

我从https://windows.php.net/downloads/pecl/releases/pcov/1.0.9/php_pcov-1.0.9-7.4-ts-vc15-x64.zip安装了 PCOV 1.0.9 线程安全版本并复制过来php_pcov.dll 到 xampp 下的 php/ext 文件夹，并在 php.ini 中启用它。我在 php.ini 中有以下配置

extension=pcov
pcov.enabled = 1
pcov.directory = "<full_local_path_to_web>\web\modules\custom"

我的 index.php 中有以下代码

use SebastianBergmann\CodeCoverage\Filter;
use SebastianBergmann\CodeCoverage\Driver\Selector;
use SebastianBergmann\CodeCoverage\CodeCoverage;
use SebastianBergmann\CodeCoverage\Driver\PhpdbgDriver;

use SebastianBergmann\CodeCoverage\Report\Html\Facade as HtmlReport;

$autoloader = require_once 'autoload.php';

$current_dir = __DIR__;

$filter = new Filter;
$filter->includeDirectory('./modules/custom/*');
$selector = new Selector();

$coverage = new CodeCoverage(
    $selector->forLineCoverage($filter),
    $filter
);

$test_name = preg_replace("/[^A-Za-z0-9]/", '-', $_SERVER['REQUEST_URI']);
$coverage->start($test_name);

function end_coverage()
{
    global $test_name;
    global $coverage;
    global $filter;
    global $current_dir;
    $coverageName = $current_dir . '/sites/default/files/private/code_coverage/coverage-' . $test_name . '-' . microtime(true);
    
    try
    {
        $coverage->stop();
        $writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade; 
        $writer->process($coverage, $current_dir . '/report/');
        $writer = new SebastianBergmann\CodeCoverage\Report\PHP();
        $coverageName =  $current_dir . '/sites/default/files/private/code_coverage/coverage-'. $test_name . '-' . microtime(true);
        $writer->process($coverage, $coverageName . '.php');
    }
    catch (Exception $ex)
    {
        file_put_contents($coverageName . '.ex', $ex);
    }
}

register_shutdown_function('end_coverage');

我看到外观 php 文件是在相应的文件夹中创建的，但是当我尝试使用以下代码创建组合报告时，我看到 0 代码覆盖率，当我查看源视图时，所有行都显示为未执行。

<?php
include_once("autoload.php");
$coverages = glob("sites/default/files/private/code_coverage/*.php");

use SebastianBergmann\CodeCoverage\Filter;
use SebastianBergmann\CodeCoverage\Driver\Selector;
use SebastianBergmann\CodeCoverage\CodeCoverage;
use SebastianBergmann\CodeCoverage\Driver\PhpdbgDriver;

use SebastianBergmann\CodeCoverage\Report\Html\Facade as HtmlReport;

#increase the memory in multiples of 128M in case of memory error
ini_set('memory_limit', '1800M');

$filter = new Filter;
$filter->includeDirectory('./modules/custom/*');
$selector = new Selector();

$coverage = new CodeCoverage(
    $selector->forLineCoverage($filter),
    $filter
);

$final_coverage = $coverage;

$count = count($coverages);
$i = 0;
foreach ($coverages as $coverage_file)
{
    $i++;
    echo "Processing coverage ($i/$count) from $coverage_file<br>". PHP_EOL;
    require_once($coverage_file);
    $final_coverage->merge($coverage);
}

echo "Generating final report...<br>" . PHP_EOL;
$report = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
$report->process($final_coverage,"sites/default/files/private/code_coverage_reports");
echo "Report generated succesfully<br>". PHP_EOL;

为什么 PCOV 报告 0 代码覆盖率？PCOV 工作正常吗？还是我必须做更多的事情来启用手动测试的代码覆盖率测试？提前感谢您的投入。
