Espec vs JasUnit comparison of testing frameworks
What are the differences between Espec and JasUnit?

	Espec https://github.com/antonmi/espec	JasUnit http://jster.net/library/jasunit
Programming language	Elixir	JavaScript
Category	Unit Testing	Unit Testing
General info	BDD driven testing framework for Elixir It is a testing framework written from scratch which is inspired by RSpec and the main idea is to close to its perfect DSL (Domain Specific Language)	JasUnit is a slim unit testing framework for JavaScript, following the general design principles of xUnit. For testing your code, JasUnit allows you to: Create test fixtures with any number of test methods; Implement setup() and teardown() methods which are run before and after each test; Specify a namespace for a fixture for easy organisation of tests; Use the default or custom logger (default appends results to a given element); Use assertions from any scope - this isn't necessary or even really advised, but some people prefer it.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes JasUnit follows the general design principles o xUnit
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end components can be tested; there is also espec_phoenix for the Phoenix web framework	Yes JasUnit is primarily used to test front-end code and functionality
Server-side Allows testing the bahovior of a server-side code	Yes databases and server behaviour can be tested using Espec	No
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 With JasUnit you can Create test fixtures with any number of test methods Implement setup() and teardown() methods which are run before and after each test
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 JasUnit allow you to create 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
Licence Licence type governing the use and redistribution of the software	MIT License	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 It has a Built-in mocking functionality on top of Erlang 'meck' library	Yes It provides inbuilt Mocking capabilities
Grouping Allows organizing tests in groups	Yes By use of context blocksand tags functions	N/A
