README
This module adds various utilities to aid in creating integration tests for Magento 2.
Installation
Use the following commands to install:
composer require yireo/magento2-integration-test-helper --dev
Enable this module:
./bin/magento module:enable Yireo_IntegrationTestHelper
./bin/magento setup:upgrade
Using this helper to enhance your tests
Parent classes:
\Yireo\IntegrationTestHelper\Test\Integration\AbstractTestCase
\Yireo\IntegrationTestHelper\Test\Integration\GraphQlTestCase
These classes offer some utility functions plus import numerous traits (see Test/Integration/Traits/
) with PHPUnit assertions. For instance, the following test checks for the proper registration of your module:
<?php declare(strict_types=1); namespace Yireo\Example\Test\Integration; use PHPUnit\Framework\TestCase; use Yireo\IntegrationTestHelper\Test\Integration\Traits\AssertModuleIsEnabled; use Yireo\IntegrationTestHelper\Test\Integration\Traits\AssertModuleIsRegistered; use Yireo\IntegrationTestHelper\Test\Integration\Traits\AssertModuleIsRegisteredForReal; class ModuleTest extends TestCase { use AssertModuleIsEnabled; use AssertModuleIsRegistered; use AssertModuleIsRegisteredForReal; public function testIfModuleIsWorking() { $this->assertModuleIsEnabled('Yireo_Example'); $this->assertModuleIsRegistered('Yireo_Example'); $this->assertModuleIsRegisteredForReal('Yireo_Example'); } }
Toggle TESTS_CLEANUP in integration tests configuration
When running integration tests, you probably want to frequently toggle the constant TESTS_CLEANUP
from disabled
to enabled
to disabled
. The following command-line easily allows for this (assuming the file is actually dev/tests/integration/phpunit.xml
cause you shouldn't modify the *.dist
version):
bin/magento integration_tests:toggle_tests_cleanup
It is toggled. You can also set the value directly:
bin/magento integration_tests:toggle_tests_cleanup enabled
Generating the install-config-mysql.php
return array
When installing Magento - as part of the procedure of running Integration Tests - the file dev/tests/integration/etc/install-config-mysql.php
should return an array with all of your relevant settings, most importantly the database settings. By using the utility class Yireo\IntegrationTestHelper\Utilities\InstallConfig
you can quickly generate the relevant output, plus details like Redis and ElasticSearch:
<?php declare(strict_types=1); use Yireo\IntegrationTestHelper\Utilities\InstallConfig; return (new InstallConfig()) ->addDb('mysql80_tmpfs') ->addRedis() ->addElasticSearch('elasticsearch6') ->get();
Disable modules when installing Magento
When installing Magento - as part of the procedure of running Integration Tests - the file dev/tests/integration/etc/install-config-mysql.php
is modified to point to your test database. There is also a flag disable-modules
that allows you to disable specific Magento modules. Disabling modules is a benefit for performance. The utility class Yireo\IntegrationTestHelper\Utilities\DisableModules
allows you to generate a listing of modules to disable quicker.
In the following example, first all (!) modules that are listed in the global app/etc/config.php
are disabled by default. But then all Magento core modules and the module Yireo_GoogleTagManager2
are enabled (but only if they are marked as active in the global configuration):
<?php declare(strict_types=1); use Yireo\IntegrationTestHelper\Utilities\DisableModules; use Yireo\IntegrationTestHelper\Utilities\InstallConfig; $disableModules = (new DisableModules()) ->disableAll() ->enableMagento() ->enableByName('Yireo_GoogleTagManager2') ->toString(); return (new InstallConfig()) ->setDisableModules($disableModules) ->addDb('mysql80_tmpfs') ->addRedis() ->addElasticSearch('elasticsearch6') ->get();
Instead of using a hard-coded value, you might also want to set an environment variable MAGENTO_MODULE
- for instance, in the Run configuration in PHPStorm. This way, you can keep the same install-config-mysql.php
file while reusing it for various Run configurations:
MAGENTO_MODULE=Yireo_Example
Note that if your module has dependencies, they need to be added to the same environment as well:
MAGENTO_MODULE=Yireo_Example,Yireo_Foobar
If you have a lot of requirements, you can also use the MAGENTO_MODULE_FOLDER
variable instead, which parses your own etc/module.xml
and adds all declared modules to the whitelist:
MAGENTO_MODULE_FOLDER=app/code/Yireo/Example
Another example, all the Magento modules are enabled by default. But then MSI and GraphQL are disabled again, while all Yireo modules are enabled:
$disableModules = (new DisableModules()) ->disableAll() ->enableMagento() ->disableMagentoInventory() ->disableGraphQl() ->enableByPattern('Yireo_') ->toString();
Note that if there would be a module Yireo_ExampleGraphQl
then this would be first disabled with disableGraphQl()
and then re-enabled again with enableByPattern('Yireo_')
. The ordering of your methods matters!
Validating your configuration
The module also ships with a CLI command to easily check whether the currently returned setup:install
flags make sense:
$ bin/magento integration_tests:check +--------------------+--------------------+ | Setting | Value | +--------------------+--------------------+ | TESTS_CLEANUP | enabled | | TESTS_MAGENTO_MODE | developer | | DB host | mysql57_production | | DB username | root | | DB password | root | | DB name | m2_test | | DB reachable | Yes | | ES host | localhost | | ES port | 9207 | | ES reachable | Yes | | Redis host | 127.0.0.1 | | Redis port | 6379 | | Redis reachable | Yes | +--------------------+--------------------+
