Magento 2 Functional Testing

🧪 Magento 2 Functional Testing – Simulate Real User Interactions

Want to test how users actually interact with your Magento store — like clicking buttons, submitting forms, or navigating pages? That’s where Functional Testing comes in! 🕵️‍♀️ It simulates real user behavior and checks if your frontend or backend features work smoothly.

🔍 What Is MFTF?

Magento 2 uses the Magento Functional Testing Framework (MFTF) — an open-source testing framework built on top of Selenium and Codeception. It allows you to write tests in readable XML format and run them against your Magento application.

📦 Where to Place MFTF Tests

vendor/vendor-name/module-name/Test/Mftf/Test/AdminLoginTest.xml

🛠️ Example: Admin Login Test

This test logs into the Magento admin panel and checks for successful login.

<?xml version="1.0"?>
<!DOCTYPE test SYSTEM "test.dtd">
<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      name="AdminLoginTest"
      group="admin">

    <annotations>
        <annotation name="severity" value="critical"/>
    </annotations>

    <preconditions>
        <createData entity="AdminUser"/>
    </preconditions>

    <steps>
        <amOnPage url="{{AdminLoginPage.url}}"/>
        <fillField selector="{{AdminLoginPage.username}}" value="admin"/>
        <fillField selector="{{AdminLoginPage.password}}" value="admin123"/>
        <click selector="{{AdminLoginPage.loginButton}}"/>
        <see text="Dashboard"/>
    </steps>
</test>
