Phpstan Phpunit Laravel Package

phpstan/phpstan-phpunit

PHPStan extension for PHPUnit: improves type inference for mocks (intersection types for createMock/getMock), understands Foo|MockObject phpDocs, adds early-terminating methods to avoid undefined vars, and refines assert() types. Optional strict rules catch improper assertion usage.

Technical Evaluation

Architecture fit: The package is designed as a PHPStan extension, aligning perfectly with PHP's static analysis ecosystem. It extends PHPStan's core capabilities to handle PHPUnit-specific patterns without requiring major architectural changes. The modular design via neon configuration files allows seamless integration into existing PHPStan setups.

Integration feasibility: High. Installation via Composer is straightforward, and the phpstan/extension-installer automates configuration. Manual setup requires minimal edits to phpstan.neon. The package has clear documentation for both setup and usage scenarios.

Technical risk: Moderate. Potential false positives may occur with legacy test patterns or non-standard PHPUnit usage. Compatibility with PHPUnit versions
