README

Description

The Magento 2 Offers module allows you to manage offer banners assigned to one or more categories. It includes a back-office menu to manage offers and displays the offers on the chosen categories in the front-office based on the start and end display dates.

Features

Backend Features

  • Admin can manage Offers Banners via a custom backend UI (grids and forms).
  • Each offer supports:
    • Title (label)
    • Image upload
    • Link (URL)
    • Start and end date
    • Assignment to one or multiple category IDs

Frontend Features

This module uses Swiper to create a responsive, animated banner slider on the category page.

  • Swiper is initialized via RequireJS (requirejs-config.js).
  • Styles are loaded via _module.less and Swiper’s own CSS.
  • Swiper pagination, navigation arrows, and autoplay features are supported.
  • The slider is rendered using a .phtml template and animated with JavaScript.

This integration ensures a smooth and interactive experience for customers browsing category pages.

Installation

To install this module via Composer, execute the following commands:

composer require dnd/offers-module
bin/magento module:enable Dnd_OffersBanner
bin/magento setup:upgrade
bin/magento setup:di:compile

For information about a module installation in Magento 2, see Manage third-party extensions.

Store Configuration

At Stores > Configuration > Catalog > Catalog > Offers banner

  • Enabled: Enable or disable the offers banner module
  • Default TTL (seconds): Time to cache offers when no expiration is defined (in seconds).

Manage Offers

At Marketing > Offers banner

Extensibility

Extension developers can interact with the Dnd_OffersBanner module. For more information about the Magento extension mechanism, see Magento plug-ins.

The Magento dependency injection mechanism enables you to override the functionality of the Dnd_OffersBanner module.

Compatibility

This module is compatible with the Luma theme in Magento 2.
It follows Magento’s layout, block, and styling conventions to integrate smoothly with the front end.
Specific CSS adjustments are provided in the _module.less file to ensure proper visual rendering.

Performance Optimization

To ensure optimal frontend performance, the module implements several strategies:

Caching of Offers

  • Offers are cached per category using Magento's cache system.
  • Each cache entry is scoped by category ID to ensure targeted invalidation.
  • Cache TTL is calculated dynamically:
    • Based on the soonest upcoming start_date or end_date among the active offers.
    • Falls back to a configurable default (e.g., 600 seconds) if no offers exist.

This ensures offers are not shown after expiration and avoids unnecessary database queries.

Asynchronous Loading

  • Offers are loaded via AJAX on category pages to bypass Full Page Cache (FPC) and ensure freshness.
  • This allows the block to be updated without requiring full-page cache invalidation.

Styles and Scripts

  • All CSS is scoped and placed in _module.less to avoid global style pollution.
  • JS components are loaded via requirejs-config.js and initialized efficiently using data-mage-init.

Custom TTL Configuration

You can customize the default cache TTL in the Magento Admin panel under:

Stores > Configuration > Catalog > Catalog > Offers banner > Cache TTL (seconds)

This value will be used when no offers are currently active.

Running Unit and Integration Tests

This module includes a basic test setup to demonstrate how to write tests for Magento 2 modules:

  • 2 Unit Tests
  • 1 Integration Test

These tests serve as examples and starting points for extending full test coverage.

1. Prerequisites

To run unit and integration tests for the Dnd_OffersBanner module, ensure you have the following:

  • Magento 2 environment set up (with dependencies installed).
  • PHPUnit installed (Magento 2 uses PHPUnit for testing).
  • A dedicated testing database configured.

2. Configure Test Database

Before running tests, configure a test database for Magento's testing framework:

  • Create a Test Database:

    In MySQL, create a new database for testing:

CREATE DATABASE magento_integration_tests;

  • Configure the Test Database:

    Copy the install-config-mysql.php.dist file from dev/tests/integration/etc directory to dev/tests/integration/etc/install_config_mysql.php, and update the database configuration for the test environment.

    Example configuration:

        return [
            'db-host' => 'localhost',
            'db-user' => 'magento',
            'db-password' => 'magento',
            'db-name' => 'magento_integration_tests',
            'backend-frontname' => 'backend',
            'search-engine' => 'opensearch',
            'opensearch-host' => 'opensearch',
            'opensearch-port' => 9200,
            'admin-user' => \Magento\TestFramework\Bootstrap::ADMIN_NAME,
            'admin-password' => \Magento\TestFramework\Bootstrap::ADMIN_PASSWORD,
            'admin-email' => \Magento\TestFramework\Bootstrap::ADMIN_EMAIL,
            'admin-firstname' => \Magento\TestFramework\Bootstrap::ADMIN_FIRSTNAME,
            'admin-lastname' => \Magento\TestFramework\Bootstrap::ADMIN_LASTNAME,
            'amqp-host' => 'rabbitmq',
            'amqp-port' => '5672',
            'amqp-user' => 'guest',
            'amqp-password' => 'guest',
        ]

  • Ensure Database Configuration is Correct:

    Magento will use this configuration when running tests, ensuring the tests are executed on the test database.

3. Run Unit Tests

  • Copy the phpunit.xml.dist file from dev/tests/unit directory to dev/tests/unit/phpunit.xml, and update the configuration for the test environment.

    Example:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.3/phpunit.xsd"
         colors="true"
         columns="max"
         beStrictAboutTestsThatDoNotTestAnything="false"
         bootstrap="./framework/bootstrap.php">
    <testsuites>
        <testsuite name="Dnd_OffersBanner Unit Test Suite">
            <directory>../../../app/code/*/*/Test/Unit</directory>
        </testsuite>
    </testsuites>
    <php>
        <includePath>.</includePath>
        <ini name="memory_limit" value="-1"/>
        <ini name="date.timezone" value="America/Los_Angeles"/>
        <ini name="xdebug.max_nesting_level" value="200"/>
    </php>
    <listeners>
        <listener class="Magento\Framework\TestFramework\Unit\Listener\ReplaceObjectManager"/>
    </listeners>
</phpunit>
  • To run unit tests, execute the following command from the Magento root directory:
vendor/bin/phpunit -c $(pwd)/dev/tests/unit/phpunit.xml app/code/Dnd/OffersBanner/Test/Unit/

4. Run Integration Tests

  • Copy the phpunit.xml.dist file from dev/tests/integration directory to dev/tests/integration/phpunit.xml, and update the configuration for the test environment.

    Example:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.3/phpunit.xsd"
         colors="true"
         columns="max"
         beStrictAboutTestsThatDoNotTestAnything="false"
         bootstrap="./framework/bootstrap.php"
         stderr="true"
         testSuiteLoaderClass="Magento\TestFramework\SuiteLoader"
         testSuiteLoaderFile="framework/Magento/TestFramework/SuiteLoader.php">
    <testsuites>
        <testsuite name="Dnd_OffersBanner Integration Tests Real Suite">
            <directory>testsuite</directory>
            <directory>../../../app/code/*/*/Test/Integration</directory>
        </testsuite>
    </testsuites>
    <php>
        <includePath>.</includePath>

        <const name="TESTS_GLOBAL_CONFIG_DIR" value="../../../app/etc"/>
        <const name="TESTS_CLEANUP" value="disabled"/>
        <const name="TESTS_MEM_USAGE_LIMIT" value="8G"/>
        <const name="TESTS_MEM_LEAK_LIMIT" value=""/>
        <const name="TESTS_EXTRA_VERBOSE_LOG" value="1"/>

        <listener class="Magento\TestFramework\Event\PhpUnit"/>
        <listener class="Magento\TestFramework\ErrorLog\Listener"/>
    </listeners>
</phpunit>
  • To run integration tests, which require a Magento instance and a configured database, execute the following command:
vendor/bin/phpunit -c $(pwd)/dev/tests/integration/phpunit.xml app/code/Dnd/OffersBanner/Test/Integration/
