Functional tests Nette\Application\Application::$maxLoops

[Martin Štainer]

Hi,

I have multiple functional tests in my application. Each test sends at least one request to Nette\Application\Application::$requests. The 'requests' property contains the previous tests requests. This leads to a growing collection of requests, which after few tests causes an exception to be thrown at Application::140 if the number of requests exceeds the limit defined in $this->maxLoop.

Nette\Application\Application:140

if (count($this->requests) > $this->maxLoop) {
      throw new ApplicationException('Too many loops detected in application life cycle.');
}

I believe I have found a simple solution for this issue by clearing the requests property after each test.
I have added the following code to the NetteApplicationModule::_after method:

public function _after(TestInterface $test): void
{
	parent::_after($test);

        /** @var NetteDIModule $diModule */
        $diModule =  $this->getModule(NetteDIModule::class);
        /** @var Application $application */
        $application = $diModule->grabService(Application::class);

        $reflectionClass = new \ReflectionClass($application);
        $property = $reflectionClass->getProperty('requests');
        $property->setAccessible(true);
        $property->setValue($application, []);

	$_SESSION = [];
	$_GET = [];
	$_POST = [];
	$_FILES = [];
	$_COOKIE = [];
}

I am unsure if this is the best solution, so I would appreciate your thoughts. If you believe this is a suitable solution, please let me know and I will create a pull request.

Thank you for your time and efforts.

You can rebuild the container for every test or set max loop via config.

    application:
        setup:
            - $maxLoop = 100000
