Symfony is designed from the ground up with code-testability in mind. In order to make your code which utilizes session easily testable we provide two separate mock storage mechanisms for both unit testing and functional testing.
Testing code using real sessions is tricky because PHP’s workflow state is global and it is not possible to have multiple concurrent sessions in the same PHP process.
The mock storage engines simulate the PHP session workflow without actually starting one allowing you to test your code without complications. You may also run multiple instances in the same PHP process.
The mock storage drivers do not read or write the system globals session_id() or session_name(). Methods are provided to simulate this if required:
getId(): Gets the session ID.setId(): Sets the session ID.getName(): Gets the session name.setName(): Sets the session name.For unit testing where it is not necessary to persist the session, you should simply swap out the default storage engine with MockArraySessionStorage:
use SymfonyComponentHttpFoundationSessionStorageMockArraySessionStorage; use SymfonyComponentHttpFoundationSessionSession; $session = new Session(new MockArraySessionStorage());
For functional testing where you may need to persist session data across separate PHP processes, simply change the storage engine to MockFileSessionStorage:
use SymfonyComponentHttpFoundationSessionSession; use SymfonyComponentHttpFoundationSessionStorageMockFileSessionStorage; $session = new Session(new MockFileSessionStorage());
