Function TestEnum

proto/proto_test.go:1208–1222

Test that enums work. Checks for a bug introduced by making enums named types instead of int32: newInt32FromUint64 would crash with a type mismatch in reflect.PointTo.

(t *testing.T)

// named types instead of int32: newInt32FromUint64 would crash with
// a type mismatch in reflect.PointTo.
func TestEnum(t *testing.T) {
	pb := new(pb2.GoEnum)
	pb.Foo = pb2.FOO_FOO1.Enum()
	o := new(proto.Buffer)
	if err := o.Marshal(pb); err != nil {
		t.Fatal("error encoding enum:", err)
	}
	pb1 := new(pb2.GoEnum)
	if err := o.Unmarshal(pb1); err != nil {
		t.Fatal("error decoding enum:", err)
	}
	if *pb1.Foo != pb2.FOO_FOO1 {
		t.Error("expected 7 but got ", *pb1.Foo)
	}
}

// Enum types have String methods. Check that enum fields can be printed.
// We don't care what the value actually is, just as long as it doesn't crash.
