Read better test failures.

Overview

marbles is a Python unittest extension that allows test authors to write richer tests that expose more information on test failure to help you debug failing tests faster.

  • Treat test failures as documentation

  • Contextualize failures without digging through test code and dropping debugging statements everywhere

  • Write clearer, more explicit tests

Features

  • Drop-in unittest replacement

  • Information-rich failure messages

    • The full statement that failed (instead of just the last line)

    • Local variables in scope at the time the test failed

    • Optional annotation provided by the test author with details about the test

    • Ability to toggle traceback

  • Semantically-rich assertion methods

  • Assertion logging

Demo

You can run the example tests provided to see what a marbles failure message looks like

You can also run your existing unittest tests with marbles

python -m marbles test_module.py

Marbles also creates a setuptools command so if you are used to running python setup.py test, you can now run:

python setup.py marbles

You can go one step further and alias the command test to run marbles by adding the following to setup.cfg:

[aliases]
test = marbles
