Runs notebooks top-to-bottom and executes any embedded unittest or doctest without requiring additional test code, enabling quick validation from the start.

Uses multithreaded execution to test multiple notebooks concurrently, significantly reducing test time for large projects as highlighted in the usage example.

Executes each notebook in a new kernel to prevent hidden state issues, ensuring reliable and reproducible test results in notebook workflows.

Command-line interface with options for paths, threads, and exclusions makes it straightforward to integrate into continuous integration systems, as emphasized in the philosophy.
