Project description
unittest_assertions
Thin wrapper around the python builtin unittest
allowing developers to use the builtin assertions for non-unittest use cases.
Key Features:
- Easy: Designed to make it be simple allowing developers to use the builtin unittest assertions for their own use cases.
- Great Developer Experience: Being fully typed, documented, and tested makes it great for editor support and extension.
- There is More!!!:
- assertify: Simple, Flexible, and Extendable python3.6+ library to evaulate an expression and return
True
/False
or raise an AssertionError
or Exception
.
- assertify_predicates: Is an extension of Assertify which allows for assertifying predicates. This is useful for validating variables or user input.
- descriptify: Descriptify is a library that contians helpful python descriptors. It uses
assertify_predicates
to validate various descriptors.
Installation
pip install unittest-assertions
Examples
from unittest_assertions.identity import AssertIsInstance
assert_is_instance = AssertIsInstance()
assert_is_instance("example str", int) # raise TypeError("'example str' is not an instance of <class 'int'> : Raised a AssertionError")
from unittest_assertions.comparison import AssertEqual
assert_equal = AssertEqual()
assert_equal(1,1)
assert_equal(first="hello",second="hello")
from unittest_assertions.container import AssertNotIn
assert_in = AssertNotIn()
assert_in(member=1,container=[5,2,3])
