Test files generated using the gnostic library that interconverts between .pb (protobuf) and .json/.yaml (Swagger OpenAPI2/3) files.
To view binary code inside .pb file, download it and view in an editor for example sublime text. So something like:
�status��
��string
looks like:
<0x06>status<0x12><0x0b>
Ê<0x01><0x06>string
