Build a kernel for testings.

Because the bootstrap is in DrupalKernel::boot and that involved loading settings from the filesystem we need to go to extra lengths to build a kernel for testing.

Parameters

\Symfony\Component\HttpFoundation\Request $request: A request object to use in booting the kernel.

array $modules_enabled: A list of modules to install on the kernel.

Return value

\Drupal\Core\DrupalKernel New kernel for testing.
