Test’em vs Tyrtle comparison of testing frameworks
What are the differences between Test’em and Tyrtle?

	Test’em https://github.com/testem/testem	Tyrtle https://github.com/spadgos/tyrtle
Programming language	JavaScript	JavaScript
Category	Unit Testing	Unit Testing
General info	A Unit testing test runner for JavaScript Test'em is framework agnostic and has support for Jasmine, Qunit, Mocha and others through custom test framework adapters. It canalso run tests on all major browsers as well as Node and Phantomjs	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.	It has an xUnit reporter	N/A
Client-side Allows testing code execution on the client, such as a web browser		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 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		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.		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
Licence Licence type governing the use and redistribution of the software		GNU GPL
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 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		N/A
