Using globals in functional tests (with Symfony and Codeception)

I want to test this function:

static protected function getContainerInterface()
{
    global $kernel;
    if (get_class($kernel) == 'AppCache') {
        /** @var \AppCache $cache */
        $cache = $kernel;
        $kernel = $cache->getKernel();
    }
    return $kernel->getContainer();
}

And got an error: Call to a member function getContainer() on null triggered by this string:

return $kernel->getContainer();

How can I pass global $kernel object to crawler( that is instance of FunctionalTester) in codeception ?

Solution

  • A global variable is a bad practice. I can assume that when running tests, codeception creates its own test kernel and this kernel can not be used globally. This place needs to be refactored
