unittest-assertions 3.1

No project description provided

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 evaluate an expression and return True/False or raise an AssertionError or Exception.

Installation

pip install unittest-assertions

Examples

from unittest_assertions.identity import AssertIsInstance

assert_is_instance = AssertIsInstance(msg="Raised an AssertionError")
assert_is_instance("example str", int) # raise AssertionError("'example str' is not an instance of <class 'int'> : Raised an AssertionError")

from unittest_assertions import AssertEqual

assert_equal = AssertEqual()
assert_equal(1, 1)
assert_equal(first="hello", second="hello")

from unittest_assertions import AssertNotIn
assert_in = AssertNotIn()
assert_in(member=1, container=[5,2,3])
