Simple assertion library for unit testing in python with a fluent API

Project description

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


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(['a', 'b', 'c']).contains('a').does_not_contain('x')

Of course, assertpy works best with a python test runner like pytest (our favorite) or Nose.


The assertpy library is available via PyPI. Just install with:

pip install assertpy

Or, if you are a big fan of conda like we are, there is an assertpy-feedstock for Conda-Forge that you can use:

conda install assertpy --channel conda-forge
