We put test inputs and outputs in testdata/test_name.in.textpb and testdata/test_name.out.textpb, respectively. Way nicer than defining both your inputs and your desired outputs in go code, even compared to not using protobuf at all, to the point where we occasionally write some proto definitions just for test inputs and outputs.
