This document outlines a comprehensive testing strategy for the QDR Temporary Shared Storage plugin to ensure all components function correctly after refactoring.
To implement automated testing for this plugin, you can use the WordPress testing framework which is based on PHPUnit.
Install PHPUnit:
composer require --dev phpunit/phpunit
Install WordPress Test Library:
bash bin/install-wp-tests.sh wordpress_test root '' localhost latest
Create a PHPUnit Configuration File (phpunit.xml):
<phpunit
bootstrap="tests/bootstrap.php"
backupGlobals="false"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
>
<testsuites>
<testsuite name="QDR Temporary Shared Storage Test Suite">
<directory prefix="test-" suffix=".php">./tests/</directory>
</testsuite>
</testsuites>
</phpunit>
Create Bootstrap File (tests/bootstrap.php):
<?php
/**
* PHPUnit bootstrap file
*/
// Require composer dependencies
require_once dirname(dirname(__FILE__)) . '/vendor/autoload.php';
// Load the WordPress test suite
$_tests_dir = getenv('WP_TESTS_DIR');
if (!$_tests_dir) {
$_tests_dir = '/tmp/wordpress-tests-lib';
}
// Load WordPress test framework
require_once $_tests_dir . '/includes/functions.php';
/**
* Load the plugin being tested
*/
function _manually_load_plugin() {
require dirname(dirname(__FILE__)) . '/qdr-temporary-shared-storage.php';
}
tests_add_filter('muplugins_loaded', '_manually_load_plugin');
// Start up the WordPress test environment
require $_tests_dir . '/includes/bootstrap.php';
Create a file tests/test-db-manager.php:
<?php
/**
* Class TestDbManager
*
* @package QDR_Temporary_Shared_Storage
*/
class TestDbManager extends WP_UnitTestCase {
/**
* Setup function runs before each test
*/
public function setUp() {
parent::setUp();
$this->db_manager = QDR_TSS_DB_Manager::instance();
}
/**
* Test creating the database table
*/
public function test_create_table() {
global $wpdb;
// Delete table if it exists
$table_name = $wpdb->prefix . QDR_TSS_PLUGIN_TABLE;
$wpdb->query("DROP TABLE IF EXISTS $table_name");
// Create table
$result = $this->db_manager->create_table();
// Check if table exists
$table_exists = $wpdb->get_var("SHOW TABLES LIKE '$table_name'") === $table_name;
$this->assertTrue($table_exists);
}
/**
* Test inserting an item
*/
public function test_insert_item() {
$data = array(
'media_id' => 123456789,
'original_file_name' => 'test.pdf',
'description' => 'Test description',
'message' => 'Test message',
'active_from' => current_time('mysql'),
'active_to' => date('Y-m-d H:i:s', strtotime('+30 days')),
'password' => wp_hash_password('test_password'),
'reference' => 'TEST123',
'file_path' => 'test/path/test.pdf',
'file_size' => 1024
);
$item_id = $this->db_manager->insert_item($data);
$this->assertNotFalse($item_id);
$this->assertGreaterThan(0, $item_id);
// Get the item and verify data
$item = $this->db_manager->get_item($item_id);
$this->assertEquals($data['media_id'], $item->media_id);
$this->assertEquals($data['original_file_name'], $item->original_file_name);
$this->assertEquals($data['description'], $item->description);
}
// Additional tests for update, delete, get operations...
}
Create a file tests/test-file-manager.php:
<?php
/**
* Class TestFileManager
*
* @package QDR_Temporary_Shared_Storage
*/
class TestFileManager extends WP_UnitTestCase {
/**
* Setup function runs before each test
*/
public function setUp() {
parent::setUp();
$this->file_manager = QDR_TSS_File_Manager::instance();
}
/**
* Test initializing the file system
*/
public function test_init_file_system() {
$result = $this->file_manager->init_file_system();
$this->assertTrue($result);
$this->assertTrue(file_exists(QDR_TSS_UPLOADS_DIR));
$this->assertTrue(file_exists(QDR_TSS_UPLOADS_DIR . 'tmp/'));
$this->assertTrue(file_exists(QDR_TSS_UPLOADS_DIR . '.htaccess'));
}
/**
* Test creating a dated directory
*/
public function test_create_dated_directory() {
$date = date('Y/m/d');
$dir = $this->file_manager->create_dated_directory($date);
$this->assertTrue(file_exists($dir));
}
// Additional tests for chunked uploads, file deletion, etc...
}
Create a file tests/test-rest-api.php:
<?php
/**
* Class TestRestApi
*
* @package QDR_Temporary_Shared_Storage
*/
class TestRestApi extends WP_UnitTestCase {
/**
* Setup function runs before each test
*/
public function setUp() {
parent::setUp();
global $wp_rest_server;
$this->server = $wp_rest_server = new WP_REST_Server;
do_action('rest_api_init');
// Set up API key
$settings = QDR_TSS_Settings::instance();
$this->api_key = $settings->generate_api_key();
$settings->update_setting('api_key', $this->api_key);
}
/**
* Test unauthorized access
*/
public function test_unauthorized_access() {
$request = new WP_REST_Request('GET', '/qdr-tss/v1/media');
$response = $this->server->dispatch($request);
$this->assertEquals(403, $response->get_status());
}
/**
* Test authorized access
*/
public function test_authorized_access() {
$request = new WP_REST_Request('GET', '/qdr-tss/v1/media');
$request->add_header('X-Api-Key', $this->api_key);
$response = $this->server->dispatch($request);
$this->assertEquals(200, $response->get_status());
}
// Additional tests for other API endpoints...
}
Run the tests using the PHPUnit command:
./vendor/bin/phpunit
To test integration with client applications, you can create simple client scripts in PHP, JavaScript, or other languages that communicate with your WordPress site's REST API.
<?php
// Define API credentials
$api_url = 'https://your-wordpress-site.com/wp-json/qdr-tss/v1';
$api_key = 'your-api-key-here';
// Test the API
function test_api() {
global $api_url, $api_key;
// Test initialization
$init_response = initialize_upload('test.txt', 1024);
if (!isset($init_response['upload_id'])) {
echo "FAIL: Initialize upload\n";
return;
}
echo "PASS: Initialize upload\n";
// Test chunk upload
$upload_id = $init_response['upload_id'];
$chunk_response = upload_chunk($upload_id, 0, 1, 'Test content');
if (!isset($chunk_response['status']) || $chunk_response['status'] !== 'chunk_uploaded') {
echo "FAIL: Upload chunk\n";
return;
}
echo "PASS: Upload chunk\n";
// Test finalize upload
$finalize_response = finalize_upload($upload_id, 1, 'test.txt', 'Test description', 'test_password');
if (!isset($finalize_response['media_id'])) {
echo "FAIL: Finalize upload\n";
return;
}
echo "PASS: Finalize upload\n";
// Test get media
$media_id = $finalize_response['media_id'];
$get_response = get_media($media_id);
if (!isset($get_response['media_id']) || $get_response['media_id'] != $media_id) {
echo "FAIL: Get media\n";
return;
}
echo "PASS: Get media\n";
// Test update media
$update_response = update_media($media_id, ['message' => 'Updated message']);
if (!isset($update_response['message']) || $update_response['message'] !== 'Updated message') {
echo "FAIL: Update media\n";
return;
}
echo "PASS: Update media\n";
// Test delete media
$delete_response = delete_media($media_id);
if (!isset($delete_response['deleted']) || $delete_response['deleted'] !== true) {
echo "FAIL: Delete media\n";
return;
}
echo "PASS: Delete media\n";
echo "All tests passed!\n";
}
// API helper functions
function initialize_upload($filename, $filesize) {
global $api_url, $api_key;
$ch = curl_init("$api_url/upload/init");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
"X-Api-Key: $api_key",
'Content-Type: application/json'
]);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
'original_file_name' => $filename,
'file_size' => $filesize
]));
$response = curl_exec($ch);
curl_close($ch);
return json_decode($response, true);
}
// Implement other API helper functions...
// Run tests
test_api();
To test the performance of the plugin, especially with large files and under high load, you can use tools like Apache JMeter or a simple script to simulate multiple concurrent uploads.
Large File Upload: Test uploading a very large file (1GB+) and measure:
Concurrent Uploads: Test multiple clients uploading files simultaneously and measure:
Storage Limit Testing: Test behavior when approaching and exceeding storage limits.
API Authentication:
File Access:
Input Validation:
File Operations:
This comprehensive testing approach will help ensure that the refactored QDR Temporary Shared Storage plugin works correctly across all components and integrates properly with WordPress and client applications. By following this guide, you can identify and fix any issues before deploying the plugin to production environments.
