Method Result

recorder_test.go:201–258

Result returns the response generated by the handler. The returned Response will have at least its StatusCode, Header, Body, and optionally Trailer populated. More fields may be populated in the future, so callers should not DeepEqual the result in tests. The Response.Header is a snapshot of the h
