assertpy

assertpy

Simple assertions library for unit testing in Python with a nice fluent API. Supports both Python 2 and 3.

Usage

Just import the assert_that function, and away you go...::

from assertpy import assert_that

def test_something():
    assert_that(1 + 2).is_equal_to(3)
    assert_that('foobar').is_length(6).starts_with('foo').ends_with('bar')
    assert_that(['a', 'b', 'c']).contains('a').does_not_contain('x')

Of course, assertpy works best with a python test runner like pytest <http://pytest.org/>_ (our favorite) or Nose <http://nose.readthedocs.org/>_.

Install

The assertpy library is available via PyPI <https://pypi.org/project/assertpy/>_. Just install with::

pip install assertpy

Or, if you are a big fan of conda <https://conda.io/>_ like we are, there is an assertpy-feedstock <https://github.com/conda-forge/assertpy-feedstock>_ for Conda-Forge <https://conda-forge.org/>_ that you can use::

conda install assertpy --channel conda-forge
