pytest assert writer

Project description

# asserted
[![Travis Status](](
[![GitHub Releases](](
[![PyPI version](](

asserted is a simple tool that writes a pytest for the object your pass to it.
This is no way near perfect, you still have to handle imports, fixtures at but its handy if you need to check that all the properties are correct.

#### CLI:
asserted path/to/file
usage: asserted [-h] [-oa] [-wf] [-tp] [-sp SAVE_PATH] [-sm] [-st] [-q] fp

positional arguments:
fp The file you want to write test for.

optional arguments:
-h, --help show this help message and exit
-oa, --only_attributes
only attributes
-wf, --write_full_tests
write tests
-tp, --test_prefix test prefix
-sp SAVE_PATH, --save_path SAVE_PATH
-sm, --separate_methods
Separate methods to there own test functions.
-st, --sort_iterables
Separate methods to there own test functions.
-q Disable logging.

#### Code:
Say you have a class like:
class Ex(object):
def __init__(self): = 'data'
self.att1 = 'att1'
self.is_list = []
self.is_dict = {}
self.is_int = 1
self.is_float = 0.5
self.is_generator_expression = (i for i in range(2))
self.is_datetime = datetime.datetime(1970, 1, 1)

def props(self):
return 'props'

def method(self):
return 'method'

async def async_metod(self):
return 'async_metod'

async def async_metod_two(self):
return 'async_metod_two'

def a_classmethod(cls):
return 'a_classmethod'

def a_staticmethod():
return 'a_staticmethod'

def a_coro_with_return(self):
return 'a_coro_with_return'

def a_generator_function(self):
for i in range(3):
yield i

def a_missing_arg(self, arg):
return arg

assert_write(asserted.example_class.Ex(), write_full_tests=True, separate_methods=True, sort_iterables=True)
# Will create the code below.
