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

	Shoulda https://github.com/thoughtbot/shoulda	Kahlan https://github.com/kahlan/kahlan
Programming language	Ruby	PHP
Category		Unit Testing
General info	Meta gem containing Shoulda Context and Shoulda Matchers Shoulda contains two other gems: Should Context and Shoulda Matchers. Should Context allows better naming and grouping of your tests. Shoulda Matchers provides a set of "matchers", i.e. methods that allow you to write much more concise assertions.	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	N/A	Yes Kahlan allows you to test front-end components and behaviour easily
Server-side Allows testing the bahovior of a server-side code	N/A	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	N/A	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.	N/A	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)	N/A	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	Yes Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping
Other Other useful information about the testing framework	Shoulda Context is compatible with Minitest and Test::Unit. Shoulda Matchers is compatible with RSpec and Minitest.
