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

	JasUnit http://jster.net/library/jasunit	Behat https://docs.behat.org/en/latest/
Programming language	JavaScript	PHP
Category	Unit Testing	Functional/Acceptance 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.	Behat is an open source Behavior-Driven Development framework for PHP. Behat uses the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD); This means the tests we write with Behat look rather like stories than code. It is inspired by Ruby's Cucumber
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	No
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 To enable Behat to test a website, you need to add Mink and a browser emulator (selenium maybe, though slow) to the mix. Mink methods are the connector between Behat and an extensive list of available drivers, and they provide a consistent testing API.
Server-side Allows testing the bahovior of a server-side code	No	Yes Behat can be used for Data Integrity Testing to verify that database operations are functioning properly
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 One can use the 'Doctrinefixturesbundle' to create the required fixture loaders and load them in our Behat scenarios when required, using the 'BeforeScenario' hook.
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 Behat allows for 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.		By use of third party libraries like moodle-behat-generators
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	By using third party libraries like Mock and Prophecy
Grouping Allows organizing tests in groups	N/A	Yes You can use tags to group features and scenarios together, independent of your file and directory structure
