Registry: Yes its waiting for an officer to be assigned to. Mine(and my wife's) file were at registry till sometime May but suddenly we got test notification 2 weeks ago.
Test ready: But for
@rajkamalmohanram, he/she waited months/weeks before getting test email even though the location was test-ready long ago.
