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

	Kahlan https://github.com/kahlan/kahlan	PHPSpec https://www.phpspec.net/en/stable/
Programming language	PHP	PHP
Category	Unit Testing	Unit Testing
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	PhpSpec is a testing tool based on the concept of emergent design using specification PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line
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	Yes By testing your PHP classes that run your front-end
Server-side Allows testing the bahovior of a server-side code	Yes You can test individual back-end components using Kahlan	Yes You can use PHPSpec to test your PHP classes that run your back-end
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 You can define fixtures
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 You can define 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	Yes There are methods that act as generators
Licence Licence type governing the use and redistribution of the software	MIT License	Free
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 It has built in support for Mocks
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	In PHPspec, you can group specification files by a certain namespace in a suite
