Magento 2 Testing Framework

Magento 2 static/unit testing framework for a single module tests. It can be used for a pipeline or to verify a Magento 2 module.

Installation

Run the following command on your Magento 2 project:

Pipeline Examples

Assumes $MAGENTO_USER and $MAGENTO_PASS set as pipeline variables.

• Bitbucket pipelines
• Gitlab CI

  ---

Basic Usage

In the most cases you may use basic test suite to run PHP code, JavaScript, PhpUnit tests.

PHP Code

There is an option to run all php tests using one command. It runs following tests:

• PHP Coding Standard Verification
• Code Integrity Tests
• HTML Static Code Analysis
• Less Static Code Analysis
• GraphQL Static Code Analysis

You can run all tests by using the command:

When you need to delete test files you can use the cleanup command:

PHPUnit

Run unit tests and check for code coverage threshold.

After execution following reports generated:

• JUnit log test-reports/junit.xml
• Html test coverage report test-coverage-html/
• Clover test coverage report clover.xml

To set code coverage threshold 80% (The default value 70%):

Javascript

Run ESLint to ensure the quality of your JavaScript code:

Advanced Usage

PHP Coding Standard Verification

These testsuite include: PHPCS, PHPMD, PHPCPD, PHPStan Tests and strict types declaration. You can run it exclusively using the following command:

Code Integrity Tests

You can run it exclusively using the following command:

HTML Static Code Analysis

You can run it exclusively using the following command:

Less Static Code Analysis

You can run it exclusively using the following command:

GraphQL Static Code Analysis

You can run it exclusively using the following command:

PHP Code Beautifier and Fixer (PHPCBF)

To automatically fix as many sniff violations as possible, use the phpcbf command:

Ignoring Files and Folders

Specific files/folders can be added to blacklist at the module folder by adding at new line

PHPCS

PHPMD

PHPCPD

Strict Type Declarations

PHPStan

Information About Tests

Magento Specific Rules

AllPurposeAction

Controllers (classes implementing ActionInterface) have to implement marker HttpActionInterface to restrict incoming requests by methods.

CookieAndSessionMisuse

Sessions and cookies must only be used in classes directly responsible for HTML presentation because Web APIs do not rely on cookies and sessions. If you need to get current user use Magento\Authorization\Model\UserContextInterface

FinalImplementation

Final keyword is prohibited in Magento as this decreases extensibility and customizability. Final classes and method are not compatible with plugins and proxies.

Code Integrity Tests

The command above will perform following tests:

• Compiler test. Check compilation of DI definitions and code generation
• Test block names exists
• Test layout declaration and usage of block elements
• Test format of layout files
• Test layout declaration and usage of block elements
• Test declarations of handles in theme layout updates
• Test ACL in the admin area by various assertions.
• Find adminhtml/system.xml files and validate them.
• Find fieldset.xml files and validate them.
• Check interfaces inherited from \Magento\Framework\Api\ExtensibleDataInterface.
• Find webapi xml files and validate them.
• Find widget.xml files and validate them.
• Scan source code for references to classes and see if they indeed exist.
• A test that enforces validity of composer.json files and any other conventions in Magento components.
• Validates information on the dependency between the modules according to the declarative schema.
• Oberver Implementation. (PAY ATTENTION: Current implementation does not support of virtual types)
• Scan source code for incorrect or undeclared modules dependencies.
• Check Magento modules structure for circular dependencies
• Verify whether all payment methods are declared in appropriate modules
• Tests to find obsolete install/upgrade schema/data scripts.
• Coverage of obsolete nodes in layout
• Static test for phtml template files.
• Less Static Code Analysis
• GraphQL Static Code Analysis
• Scan source code for detects invocations of outdated __() method.
• Scan source code for detects invocations of __() function or Phrase object, analyzes placeholders with arguments and see if they not equal.
• Will check if phrase is empty.
• xsi:noNamespaceSchemaLocation validation.
• XML DOM Validation.
