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

	Kahlan https://github.com/kahlan/kahlan	Tyrtle https://github.com/spadgos/tyrtle
Programming language	PHP	JavaScript
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	Tyrtle is a Javascript unit testing framework that emphasises simplicity, cleanliness and expressiveness. Tyrtle runs either in the browser or on NodeJS. In a CommonJS environment (eg: Node, or the browser running RequireJS), nothing is added to the global space, and with plain Javascript in the browser, only one variable is added to the window object. This keeps it clean and ensures that it won't interfere with your codebase.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	N/A
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 pieces of code can be tested, you can test various components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can test individual back-end components using Kahlan	Yes Back-end components and functions can be tested using tyrtle
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	N/A
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	N/A
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

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 By using Myrtle, a sister project of Tyrtle which provides various Mocking features such as: -Mocking (spying and stubbing functions); -Mock function generation; -Timer manipulation-Speed profiling
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	N/A
