In Magento 2, testing is a mandatory part of various processes: upgrading the Magento platform developing extensions, making customizations, and many more to detect introduced bugs early and improve the code quality.
Though testing can be performed manually or automatically, Magento 2 automation tests are highly recommended. Thanks to automation tests in Magento 2, testers can:
- Simplify Magento QA testing procedures
- Save precious time and human resources
- Take the full management over the test result
- Good for Magento a/b testing
- Adjust the test’s input data or preconditions freely
- Re-run Magento 2 automation tests dynamically
In this post, we will have a brief introduction of the Magento 2 automation test installation and how to create a test case in several simple settings. This guide is especially useful for Magento 2 developers as well as for PHP developers, Magento QA testing specialists, Magento A/B testing experts, and system integrators.
I. Installation:
A. Adjust configuration:
1. Edit phpunit.xml to configure PHPUnit
In <magento2_root_dir>/dev/tests/functional, please find phpunit.xml and open it in editor.
If you cannot find phpunit.xml, create it from phpunit.xml.dist.
Set URL for Magento storefront under test
Find <php> element.
For name=”app_frontend_url” set value that is your actual URL for Magento storefront under test.
Example:
http://127.0.0.1/magento223-bk/”/>
Set URL for Magento Admin URL under test
For name=”app_backend_url” set value that is your actual URL for Magento Admin URL under test.
Example:
http://127.0.0.1/magento223-bk/admin/”/>
2. Edit config.xml to configure Magento Functional Testing Framework
It is recommended to edit the code on the Magento functional testing framework.
In <magento2_root_dir>/dev/tests/functional/etc, find config.xml and open it in editor.
If you cannot find config.xml, create it from config.xml.dist.
Set credentials for Magento Admin under test
In <application> element, find elements <backendLogin> and <backendPassword>. Change content of these elements to your actual credentials for Magento Admin URL.
Set browser that the FTF will use for tests
Copy <server> element from <magento2_root_dir>/dev/tests/functional/vendor/magento/mtf/etc/config.xml> and paste it in <magento2_root_dir>/dev/tests/functional/etc/config.xml after <install> element.
Enter actual data in <browserName> and <browser> attributes.
If set in Google Chrome:
<server> <item name=”selenium” type=”default” browser=”Google Chrome” browserName=”chrome” host=”localhost” port=”4444″ seleniumServerRequestsTimeout=”90″ sessionStrategy=”shared”> <desiredCapabilities> <platform>ANY</platform> </desiredCapabilities> </item> </server>

Enter in terminal:
cd <magento2_root_dir>/dev/tests/functional/utils
php generate.php
D. Test run:
1. Run all tests
Enter in terminal:
cd <magento2_root_dir>/dev/tests/functional
vendor/bin/phpunit
2. Run particular test
Enter in terminal:
cd <magento2_root_dir>/dev/tests/functional vendor/bin/phpunit –filter <name of test>
Example:
Let’s check the creation of new category. For this we should run <magento2_root_dir>/dev/tests/functional/tests/app/Magento/Catalog/Test/TestCase/Category/CreateCategoryEntityTest.php. To run this test enter the following script in your terminal:
cd <magento2_root_dir>/dev/tests/functional
vendor/bin/phpunit –filter CreateCategoryEntityTest

All failed tests are logged in <magento2_root_dir>/dev/tests/functional/var/log.
All Magento errors are logged in <magento2_root_dir>/var/log.
