Maybe you got a rejected response.

Scenario 2: Failed Authentication Attempt
Let's see how the output appears when a username/password entry results in a failed authentication.

(Cisco Controller) >test aaa show radius                                                                          
Radius Test Request
  Wlan-id........................................ 1
  ApGroup Name................................... default-group
  Server Index................................... 2
Radius Test Response
Radius Server            Retry Status
-------------            ----- ------
10.20.227.52            1     Success
Authentication Response:
  Result Code: Authentication failed  ------>This indicates that the user authentication will fail.
  No AVPs in Response
In this case, you can see that the connectivity test resulted in a 'Success', however the radius server sent an access-reject for the username/password combination used.

Please check the configuration and account password in conjunction with the RADIUS server and WLC.
