phpstan.classNotFound

Code example

This error is reported during PHPStan's internal testing when a class being analysed cannot be found via the reflection provider.

Why is it reported?

The class under analysis is not autoloadable. This typically occurs when the autoload-dev section in composer.json is not configured to include the test directories, or when the class file is not included in the analysis paths.

How to fix it

Ensure your composer.json autoload-dev section includes the directory containing the class:

{
	"autoload-dev": {
		"psr-4": {
			"App\\Tests\\": "tests/"
		}
	}
}

Then run composer dump-autoload to regenerate the autoloader.
