Kiwi vs unittest2 comparison of testing frameworks
What are the differences between Kiwi and unittest2?

	Kiwi https://github.com/kiwi-bdd/Kiwi	unittest2 https://pypi.org/project/unittest2/
Programming language	Swift	Python
Category	Unit Testing	Unit Testing
General info	Kiwi is a Behavior Driven Development library for iOS development The goal behind Kiwi is to provide a BDD library that is simple to setup and use, and create tests that are more readable than what is possible with the bundled test framework.	Unittest2 is a newer version on the inbuilt unit testing framework unittest To use o use unittest2 instead of unittest, simply replace 'import unittest' with 'import unittest2'. It has many new features such as: - addCleanups for better resource management; -many new assert methods; - assertRaises as context manager, with access to the exception afterwards; - test discovery and new command line options (including failfast and better handling of ctrl-C during test runs); - class and module level fixtures: setUpClass, tearDownClass, setUpModule, tearDownModule; -test skipping and expected failures and many more improvements on the API and bug fixes
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Kiwi is an xUnit style framework	Yes unittest2 is a newer version of unittest which is an xUnit style framework for Python.
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components with kiwi	Yes Front-end functionality and behaviour can be tested by unittest2. function by function
Server-side Allows testing the bahovior of a server-side code	Yes You can test back-end components with kiwi	Yes We can write tests with unittest2 to test each function for server-side behaviour
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		Yes By use of the 'setUp()' function which is called to prepare the test fixture
Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	Yes kiwi has a beforeEach(aBlock) which is run before every 'it' block in all enclosed contexts. Code that sets up the particular context should go here and afterEach(aBlock) which is run after every it block in all enclosed contexts	Yes unittest2 allows you to group your initialization code buy use of the 'setUp()' function and clean up code with a 'tearDown()' function
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.	Yes through the beforeAll(aBlock) and afterAll(aBlock) functions.	Yes unittest2 contains generator methods in the module 'unittest.TestCase'
Licence Licence type governing the use and redistribution of the software	Proprietary, Open source	MIT License
Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	Yes Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks	Yes Mocks are available from the library unittest.mock which allows you to replace parts of your system under test with mock objects
Grouping Allows organizing tests in groups	Yes Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests	Yes One can build suites either manually or use test discovery to build the suite automatically by scanning a directory
