This extension was heavily inspired by phpstan/phpstan/phpstan-webmozart-assert developed by Ondřej Mirtes.


The main scope of this extension is to help phpstan to detect the type of object after the Tester\Assert validation.

declare(strict_types = 1);

use Tester\Assert;

function runTest(?int $a) {
	// ...
	// phpstan is now aware that $a can no longer be `null` at this point
	return ($a === 10);

This extension specifies types of values passed to:

  • Assert::null()
  • Assert::notNull()
  • Assert::true()
  • Assert::false()
  • Assert::truthy()
  • Assert::falsey()
  • Assert::nan()
  • Assert::same()
  • Assert::notSame()
  • Assert::type()
  • Assert::count()


To use this extension, require it in Composer:

composer require --dev damejidlo/phpstan-nette-tester

If you also install phpstan/extension-installer then you're all set!

If you have enabled checkAlwaysTrueCheckTypeFunctionCall: true, you will need to add some ignored errors:

		- '~Call to static method Tester\\Assert::(type|count|same|notSame)\(\) with .* and .* will always evaluate to true\.~'
		- '~Call to static method Tester\\Assert::(null|notNull|true|false|truthy|falsey|nan)\(\) with .* will always evaluate to true\.~'

Manual installation

If you don't want to use phpstan/extension-installer, include extension.neon in your project's PHPStan config:

    - vendor/damejidlo/phpstan-nette-tester/extension.neon
