pytest-expecter 1.0

A fork of 'expecter' with better support for pytest.

pytest-expecter

This is a fork of garybernhardt/expecter that hides the internal stack trace for pytest.

Overview

This lets you write tests (using ropez/pytest-describe) like this:

from expecter import expect


def describe_foobar():

    def it_can_pass():
        expect(2 + 3) == 5

    def it_can_fail():
        expect(2 + 3) == 6

and instead of getting output like this:

=================================== FAILURES ===================================
_________________________ describe_foobar.it_can_fail __________________________

    def it_can_fail():
>       expect(2 + 3) == 6

test_foobar.py:14:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

self = expect(5), other = 6

    def __eq__(self, other):
        msg = 'Expected %s but got %s' % (repr(other), repr(self._actual))
        if (isinstance(other, basestring) and
                isinstance(self._actual, basestring)):
            msg += normalized_diff(other, self._actual)
        elif len(repr(self._actual)) > 74:
            msg += normalized_diff(pprint.pformat(other),
                                   pprint.pformat(self._actual))
>       assert self._actual == other, msg
E       AssertionError: Expected 6 but got 5

env/lib/python3.5/site-packages/expecter.py:57: AssertionError
====================== 1 failed, 1 passed in 2.67 seconds ======================

getting output like this:

=================================== FAILURES ===================================
_________________________ describe_foobar.it_can_fail __________________________

    def it_can_fail():
>       expect(2 + 3) == 6
E       AssertionError: Expected 6 but got 5

test_foobar.py:14: AssertionError
====================== 1 failed, 1 passed in 2.67 seconds ======================
