Better testing with expecter and pytest.
Project description
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

def it_can_fail():
