pytest-nbsmoke

Basic notebook smoke tests: Do they run ok? Do they contain lint?

WARNING: early stage proof of concept; work in progress. Use at your own risk.

In particular, this extension is supposed to handle ipython magics as far as possible, but has not yet been widely tested.


This Pytest plugin was generated with Cookiecutter along with @hackebrot’s Cookiecutter-pytest-plugin template.

Requirements

  • pytest>=3.1.1
  • jupyter_client
  • ipykernel
  • nbformat
  • nbconvert
  • pyflakes

Installation

You can install “pytest-nbsmoke” via pip from PyPI:

$ pip install pytest-nbsmoke

Usage

Check all notebooks in examples/ run without errors:

$ pytest --nbsmoke-run examples/

Check all notebooks in examples/ run without errors, and store html to look at afterwards:

$ pytest --nbsmoke-run --store-html=/scratch examples/

Lint check notebooks in examples/:

$ pytest --nbsmoke-lint notebooks/

Instead of all files in a directory, you can specify a list e.g.:

$ pytest --nbsmoke-run notebooks/Untitled*.ipynb

Additional options are available by standard pytest ‘ini’ configuration in setup.cfg, pytest.ini, or tox.ini:

[pytest]
# when running, seconds allowed per cell (see nbconvert timeout)
cell_timeout = 600

# notebooks to skip running; one case insensitive re to match per line
skip_run = ^.*skipme\.ipynb$
           ^.*skipmetoo.*$

# case insensitive re to match for file to be considered notebook;
# defaults to ``^.*\.ipynb``
it_is_nb_file = ^.*\.something$

Contributing

First, install using pip install -e .. Then run the tests using tox or pytest -v tests/.

New release to PyPI: git tag -a x.y.z -m "Something about release" && git push --tags.
