General info

Kahlan is a full-featured BDD testing framework

It is a full-featured BDD testing framework that embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan makes it possible to write unit tests using the 'describe-it' syntax and requires at least PHP 5.5

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.

No

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

Kahlan allows you to test front-end components and behaviour easily

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 individual back-end components using Kahlan

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

Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method

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

You can write group fixtures

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.

N/A

Yes

unittest2 contains generator methods in the module 'unittest.TestCase'

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

With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)

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

Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping

Yes

One can build suites either manually or use test discovery to build the suite automatically by scanning a directory
