Support utilities for enhanced testing capabilities.

Features

✅ Advanced Reflection Utilities

• Access and modify private and protected properties via reflection.
• Invoke inaccessible methods to expand testing coverage.

✅ Cross-Platform String Assertions

• Avoid false positives and negatives caused by Windows vs. Unix line ending differences.
• Normalize line endings for consistent string comparisons across platforms.

✅ File System Test Management

• Recursively clean files and directories for isolated test environments.
• Safe removal that preserves Git-tracking files (for example, '.gitignore', '.gitkeep').

Quick start

System requirements

• PHP 8.1 or higher.
• Composer for dependency management.
• PHPUnit for testing framework integration.

Installation

Method 1: Using Composer (recommended)

Install the extension.

composer require --dev --prefer-dist php-forge/support:^0.2

Method 2: Manual installation

Add to your composer.json.

{
    "require-dev": {
        "php-forge/support": "^0.2"
    }
}

Then run.

composer update

Basic Usage

Accessing private properties

<?php
declare(strict_types=1);

use PHPForge\Support\TestSupport;
use PHPUnit\Framework\TestCase;

final class AccessPrivatePropertyTest extends TestCase
{
    use TestSupport;

    public function testInaccessibleProperty(): void
    {
        $object = new class () {
            private string $secretValue = 'hidden';
        };

        $value = self::inaccessibleProperty($object, 'secretValue');

        self::assertSame('hidden', $value, "Should access the private property and return its value.");
    }
}

Invoking protected methods

<?php
declare(strict_types=1);

use PHPForge\Support\TestSupport;
use PHPUnit\Framework\TestCase;

final class InvokeProtectedMethodTest extends TestCase
{
    use TestSupport;

    public function testInvokeMethod(): void
    {
        $object = new class () {
            protected function calculate(int $a, int $b): int
            {
                return $a + $b;
            }
        };

        $result = self::invokeMethod($object, 'calculate', [5, 3]);

        self::assertSame(8, $result, "Should invoke the protected method and return the correct sum.");
    }
}

Normalize line endings

<?php
declare(strict_types=1);

use PHPForge\Support\TestSupport;
use PHPUnit\Framework\TestCase;

final class NormalizeLineEndingsTest extends TestCase
{
    use TestSupport;

    public function testNormalizedComparison(): void
    {
        self::assertSame(
            self::normalizeLineEndings("Foo\r\nBar"),
            self::normalizeLineEndings("Foo\nBar"),
            "Should match regardless of line ending style",
        );
    }
}

Remove files from directory

<?php
declare(strict_types=1);

use PHPForge\Support\TestSupport;
use PHPUnit\Framework\TestCase;

final class RemoveFilesFromDirectoryTest extends TestCase
{
    use TestSupport;

    public function testCleanup(): void
    {
        $testDir = dirname(__DIR__) . '/runtime';
        // clean up test artifacts (preserves '.gitignore' and '.gitkeep')

        self::removeFilesFromDirectory($testDir);

        self::assertTrue(true, "Should remove all files in the test directory while preserving Git-tracked files.");
    }
}

Set inaccessible property

<?php
declare(strict_types=1);

use PHPForge\Support\TestSupport;
use PHPUnit\Framework\TestCase;

final class SetInaccessiblePropertyTest extends TestCase
{
    use TestSupport;

    public function testSetProperty(): void
    {
        $object = new class () {
            private string $config = 'default';
        };

        // set private property for testing scenarios
        self::setInaccessibleProperty($object, 'config', 'test-mode');

        $newValue = self::inaccessibleProperty($object, 'config');

        self::assertSame('test-mode', $newValue, "Should set the inaccessible property to 'test-mode'.");
    }
}
