This service is running the backend of the visual testing server, which is receiving rendered images, generates comparison images and collates the result into a form usable by the frontend. The backend is accessible through a limited set of HTTP/HTTP APIs.

This service also keeps track of a set of reference images.

The available API endpoints can be queried through the /api endpoint (for example http://localhost:8000/api). This endpoint also contains all of the description for the available functions and which parameters they take. Note that some require elevated priviledges, which means that an adminToken has to be passed along with the request, which matches the adminToken provided in the config.json when starting the server.
