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

	JasUnit http://jster.net/library/jasunit	RSpec https://rspec.info
Programming language	JavaScript	Ruby
Category	Unit Testing	Unit Testing, Intergration Testing
General info	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.	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes JasUnit follows the general design principles o xUnit	Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.
Client-side Allows testing code execution on the client, such as a web browser	Yes JasUnit is primarily used to test front-end code and functionality	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.
Server-side Allows testing the bahovior of a server-side code	No	Yes You can test server-side behaviour with Rspec
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	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	Yes RSpec does contain fixture methods
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 JasUnit allow you to create group fixtures	Yes Group fixture methods are supported
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.		Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder
Licence Licence type governing the use and redistribution of the software	N/A	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)	Yes It provides inbuilt Mocking capabilities	Yes Available through rspec-mocks gem.
Grouping Allows organizing tests in groups	N/A	Yes Allows declaring example groups and contexts.
