使用具有嵌套插件依赖项的自定义wordpress插件进行单元测试

Question

所以我创建了一个自定义插件并实施了单元测试。

到目前为止，添加WooCommerce依赖项和私有插件依赖项（Iconic插件）非常容易。

问题在于Iconic插件依赖于WooCommerce。 在每次测试中，它都认为WooCommerce没有被激活。

因此，它无法正确实例化。

图标插件

class Iconic_Private_Plugin() {

    /**
     * Constructor
     */
    public function __construct() {

        public $bar;

        if ( ! Iconic_Private_Core_Helpers::is_plugin_active( 'woocommerce/woocommerce.php' ) && ! Iconic_Private_Core_Helpers::is_plugin_active( 'woocommerce-old/woocommerce.php' ) ) {
            return;
            // It stops right here!!!
        }

        $this->bar = "foo"; // Not assigned!!!

    }

}
global $iconic_private_plugin; // Methods can be accessed from global variable $iconic_private_plugin.
$iconic_private_plugin = new Iconic_Private_Plugin();

这就是我从bash命令，引导程序和单元测试中所做的事情。

install-wp-tests.sh

install_dependencies() {
    WP_SITE_URL="http://localhost:8080"
    WP_PLUGIN_DIR=$(pwd)
    WP_DB_DATA="$WP_PLUGIN_DIR/tests/data/db.sql"

    cd "$WP_CORE_DIR"
    curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
    php wp-cli.phar core config --dbname=$DB_NAME --dbuser=$DB_USER --dbpass=$DB_PASS --dbhost=$DB_HOST --dbprefix=wptests_
    php wp-cli.phar db import $WP_DB_DATA
    php wp-cli.phar search-replace "http://local.wordpress.test" "$WP_SITE_URL"
    php wp-cli.phar theme install twentyseventeen --activate
    php wp-cli.phar plugin install https://downloads.wordpress.org/plugin/woocommerce.${WC_VERSION}.zip --activate
    php wp-cli.phar plugin install https://downloads.wordpress.org/plugin/posts-to-posts.${P2P_VERSION}.zip --activate
    php wp-cli.phar plugin install $WP_PLUGIN_DIR/plugins/iconic-private-plugin.zip --activate
    php wp-cli.phar plugin list
}

bootstrap.php

/**

 */
public function __construct() {
    // phpcs:disable WordPress.PHP.DiscouragedPHPFunctions, WordPress.PHP.DevelopmentFunctions
    ini_set( 'display_errors', 'on' );
    error_reporting( E_ALL );
    // phpcs:enable WordPress.PHP.DiscouragedPHPFunctions, WordPress.PHP.DevelopmentFunctions

    // Ensure server variable is set for WP email functions.
    // phpcs:disable WordPress.VIP.SuperGlobalInputUsage.AccessDetected
    if ( ! isset( $_SERVER['SERVER_NAME'] ) ) {
        $_SERVER['SERVER_NAME'] = 'localhost';
    }
    // phpcs:enable WordPress.VIP.SuperGlobalInputUsage.AccessDetected

    $this->tests_dir    = dirname( __FILE__ );
    $this->plugin_dir   = dirname( $this->tests_dir );
    $this->wp_tests_dir = getenv( 'WP_TESTS_DIR' ) ? getenv( 'WP_TESTS_DIR' ) : rtrim( sys_get_temp_dir(), '/\\' ) . '/wordpress-tests-lib';

    // load test function so tests_add_filter() is available.
    require_once $this->wp_tests_dir . '/includes/functions.php';

    // load Dependencies.

    tests_add_filter( 'setup_theme', array( $this, 'install_wc' ) );

    // load the WP testing environment.
    require_once $this->wp_tests_dir . '/includes/bootstrap.php';
}

/**
 * Install WooCommerce after the test environment and WC have been loaded.
 */
public function install_wc() {
    // Clean existing install first.
    define( 'WP_UNINSTALL_PLUGIN', true );
    define( 'WC_REMOVE_ALL_DATA', true );
    include (ABSPATH . 'wp-content/plugins/woocommerce/uninstall.php');
    WC_Install::install();
    // Reload capabilities after install, see https://core.trac.wordpress.org/ticket/28374
    if ( version_compare( $GLOBALS['wp_version'], '4.7', '<' ) ) {
        $GLOBALS['wp_roles']->reinit();
    } else {
        $GLOBALS['wp_roles'] = null; // WPCS: override ok.
        wp_roles();
    }
    echo esc_html( 'Installing WooCommerce...' . PHP_EOL );
}


/**
 * Load Dependencies
 */
public function my_custom_plugin_manually_load_plugin() {
    $this->plugins_dir = ABSPATH . str_replace( site_url() . '/', '', plugins_url() ) . '/';

    // Load dependencies.
    require_once $this->plugins_dir . 'woocommerce/woocommerce.php';
    require_once $this->plugins_dir . 'iconic/iconic-private-plugin.php';

    // Load plugin.
    require_once $this->plugin_dir . '/my-custom-plugin.php';

    global $my_custom_plugin;
    $my_custom_plugin = new My_Custom_Plugin_Class();
}

我的单元测试

<?php
/**
 * Sql test case.
 */
class SqlTest extends WP_UnitTestCase {

    /**
     * Set up fixtures before class for all tests in SqlTest Class.
     *
     * @param object $factory passed by WP_UnitTestCase.
     */
    public static function wpSetUpBeforeClass( $factory ) {
        self::createFixtures();
        self::createSettings();
    }

    public function setUp() {
        self::set_active_plugins();
    }

    public static function set_active_plugins() {
        activate_plugin(ABSPATH . 'wp-content/plugins/woocommerce/woocommerce.php');
        activate_plugin(ABSPATH . 'wp-content/plugins/iconic/iconic-private-plugin.php');
    }

    /**
     * Warehouses fixtures
     */
    public static function createFixtures() {
        // [...]
    }

    /**
     * Create timeslots
     */
    public static function createSettings() {
        $settings = array (
            // [...]
        );

        update_option( 'iconic_private_plugin_settings', $settings );
        global $iconic_private_plugin;
        $iconic_private_plugin->settings = $settings;
    }

    /**
     * Test for custom_function.
     */
    public function test_custom_function() {
        global $my_custom_plugin, $iconic_private_plugin;

        echo $iconic_private_plugin->bar; // Has not been assigned!!! (but it should be.

        print_r($iconic_private_plugin); 
        // Class properties are empty, since construct method stop at WooCommerce activation check. (same as above example)

        $this->assertTrue(true);
    }

}

您可以看到，我什至试图直接在数据库中激活每个测试之间的插件（setUp函数）。

所以我想问题可能出在bootstrap.php

我在网络上找不到任何文档或类似问题。

唯一足够接近的东西：

WordPress plugin phpunit tests with dependencies

我也从WooCommerce测试setup中得到启发。

关于我在做什么错的任何想法吗？

更新

T.Todua's answer之后，我在控制台中抛出了一些警告。 但是，它确实解决了依赖项的实例化，并且测试按预期工作。

但是由于有这些警告，所以我想知道这是否是正确的方法和/或如何解决这些警告。

所有这些警告似乎都与Freemius依赖关系有关（由于存在或多或少的相同之处，所以只在这里放一个）。

因此可能与此问题无关。

Answer 1

使用情况如何

private function force_activate( $plugin ) {
    if( ! function_exists('activate_plugin') ) {
        require_once ABSPATH . 'wp-admin/includes/plugin.php';
    }

    if( ! is_plugin_active( $plugin ) ) {
        activate_plugin( $plugin );
    }
}



...

// Load dependencies.
require_once $this->plugins_dir . 'woocommerce/woocommerce.php';
$this->force_activate('woocommerce/woocommerce.php');
require_once $this->plugins_dir . 'iconic/iconic-private-plugin.php';
