How can I mock behavior of the services in the 'fob_symfony.driver_kernel'?

[arkadiy-lysenko]

User case:
I need to mock some services while api testing
I get from kernel instance some services and put on this service some dummy(using Prophecy)
But when behat steps are passed and request to kernel is started, kernel object have no mocked objects at all (I think this is because of two kernel's loaded)

\FriendsOfBehat\SymfonyExtension\ServiceContainer\SymfonyExtension::load $this->loadKernel($container, $this->autodiscoverKernelConfiguration($config['kernel'])); $this->loadDriverKernel($container);
I try to pass 'fob_symfony.driver_kernel' service to BehatContext to change it behavior but service doesnot exist.

How can I mock behavior of the services in the 'fob_symfony.driver_kernel'?

I use:

• Behatch/contexts(for example RestContext send request using mink driver that loaded with second kernel instance)
• Behat/MinkExtension

For now, you are probably forced to write some dummy implementation and load it only in test env, so DI will handle mocking. However some support for prophecy could be useful, but probably it won't be easy to implement.

@pamil is it something that we would like to support?

But if i implement static dummy implementation this will work only for one case.
I can't configure it in behat scenario because kernel will reboot and reset all configuration.
For my case I want to mock response from service and want to test several of responses.

@lchrusciel Can I get access to kernel object that set to mink driver? If I can get access to him I can configure it as i want using that mock library that i want(prophecy, phpunit, etc).

This issue is probably a bit related to #86, defining a stable way to get to and modify those services in Mink kernel would be certainly beneficial, although I don't have any good ideas for it now.

[pamil]

After #116 is merged, you can inject @behat.driver.service_container service to your context and access services/kernel of the tested application via Mink driver. Let me know if that solves your issue.

I've released v2.1.0-BETA.2 with #116 that should help with it. I'll close this issue, please open a new one if it isn't enough.
