Arquillian vs Wallaby.js comparison of testing frameworks
What are the differences between Arquillian and Wallaby.js?

	Arquillian http://arquillian.org/	Wallaby.js https://wallabyjs.com/
Programming language	Java	JavaScript
Category	Intergration Testing, Functional Testing	Unit Testing
General info	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well	Wallaby.js is an integrated continuous testing tool for JavaScript. Wallaby.js runs your tests immediately as you change your code (you don’t even have to save the file) and reports code coverage and other results directly to your code editor. Its also uses various techniques such as dependency analysis to only execute tests affected by your code changes and parallel test execution to ensure your tests run as fast as possible.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is a xUnit framework	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes You can perform unit tests on front-end components and functionality	Yes Wallaby.js can test front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions	Yes Wallaby.js can test server behaviour and functionality
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By use of extensions, for example you can use the Persistence extension to set database fixtures	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 define 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
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 Arquillian supports mock object functionality you can use third party libraries	By use of a third party library Jest works well with wallaby
Grouping Allows organizing tests in groups	Yes Arquilian supports grouping of tests
