 - **Commands:** The ``filter:check`` command now requires the HTTP method argument to be uppercase (e.g., ``spark filter:check GET /`` instead of ``spark filter:check get /``).
 - **Filters:** HTTP method matching for method-based filters is now case-sensitive. The keys in ``Config\Filters::$methods`` must exactly match the request method
     (e.g., ``GET``, ``POST``). Lowercase method names (e.g., ``post``) will no longer match.
+- **Testing:** Tests using the ``FeatureTestTrait`` must now use uppercase HTTP method names when performing a request when using the ``call()`` method directly
+    (e.g., ``$this->call('GET', '/path')`` instead of ``$this->call('get', '/path')``). Additionally, setting method-based routes using ``withRoutes()`` must
+    also use uppercase method names (e.g., ``$this->withRoutes([['GET', 'home', 'Home::index']])``).
