Tooling for Livebook regression Tests?

[andyl]

To document my Elixir app, I publish a livebooks in guides/*.livemd.

My livebooks have just text blocks and code blocks - no user input or UI interactions.

I'd like to run regression tests over my livebooks. The tests would require just a check to see if the livebook runs to the end and returns a success code. No intermediate assertions.

Is there is a package to run such tests?

Or can someone suggest a good approach to integrate with ExUnit or write a test runner?
