Testing

This package provides a consistent set of Composer scripts for local validation.

Tool references:

• Composer Require Checker for dependency definition checks.
• Easy Coding Standard (ECS) for coding standards.
• Infection for mutation testing.
• PHPStan for static analysis.
• PHPUnit for unit tests.

Coding standards (ECS)

Run Easy Coding Standard (ECS) and apply fixes.

composer run ecs

Shared configuration

This repository ships shared configuration files under config/ for reuse. Consumer repositories should define their own wrapper ecs.php and set project paths there.

Dependency definition check

Verify that runtime dependencies are correctly declared in composer.json.

composer run check-dependencies

Mutation testing (Infection)

Run mutation testing.

composer run mutation

Run mutation testing with static analysis enabled.

composer run mutation-static

Static analysis (PHPStan)

Run static analysis.

composer run static

Unit tests (PHPUnit)

Run the full test suite.

composer run tests

Passing extra arguments

Composer scripts support forwarding additional arguments using --.

Example: run a specific PHPUnit test or filter by name.

composer run tests -- --filter SvgTest

Example: run PHPStan with a different memory limit:

composer run static -- --memory-limit=512M
