In certain low stakes assessment with no hidden tests, it seems like Otter Grader in the notebook could report something like 10/10 test passed

Would it be possible to build a simple functionality where the students notebook reports this score via LTI back to the LMS

For instance - an Ischool online class which is only checking notebook completion, no grade
or Data 8x which doesnt even have hidden tests

The benefit would be skipping the need for a grading server

Describe the solution you'd like
A clear and concise description of what you want to happen.

Some extension to Otter Check where it

• does a run all checks above
• generates a score for the notebook
• uses course and notebook/assignment id ( poentially from notebook medatata or other source )
• user ID from jupyterhub os?
• reports via LTI back to the LMS

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Currently you need to send the grade to another server with a docker to rerun the files against hidden tests
This is a complicated workflow not needed for all cases
