405 Method Not Allowed

Error message

405 Method Not Allowed

What it means

Constant defining the 405 Method Not Allowed response expectation: with expecting(SC_METHOD_NOT_ALLOWED) (as used in HttpTest), a 405 response fails the request future. The server rejected the HTTP method for the target resource; the 'message' is the reason attached to the failure.
