There was a problem hiding this comment.
This is a valuable addition, as it effectively summarizes all the relevant aspects of session testing.

Description
This pull request introduces a dedicated “Session Testing” section that explains why session-specific testing utilities exist, how the ArrayHandler behaves in the testing environment, and how session state should be asserted correctly depending on the testing approach (unit vs feature/HTTP tests).
The changes also clarify the scope and lifecycle of session assertions, distinguishing between PHPUnit-based assertions for direct session usage and TestResponse session helpers that operate during the HTTP request/response lifecycle.
Finally, this PR improves cross-referencing between existing testing documentation to reduce confusion, avoid incorrect usage patterns, and make session testing behavior more predictable and easier to understand for developers.
See #2014
