Doctest vs Kahlan comparison of testing frameworks
What are the differences between Doctest and Kahlan?

	Doctest https://docs.Python.org/2/library/doctest.html	Kahlan https://github.com/kahlan/kahlan
Programming language	Python	PHP
Category	Unit Testing	Unit Testing
General info	Doctest is an inbuilt test framework for Python Doctest is a test framework that comes prepackaged with Python. It is a simple library with a functionality that makes it possible to search for pieces of text that look like interactive Python sessions and executes these sessions to see if they work exactly as shown.	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
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
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
Server-side Allows testing the bahovior of a server-side code		Yes You can test individual back-end components using Kahlan
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No Lacks fixture management which can make writing tests harder	Yes Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method
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.	No Lacks fixture management	Yes You can write group fixtures
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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	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)	A good external library for using Mocks with Doctest is minimocks	Yes With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)
Grouping Allows organizing tests in groups	Yes One can group tests	Yes Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping
