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

	Wallaby.js https://wallabyjs.com/	Vows http://vowsjs.org/
Programming language	JavaScript	JavaScript
Category	Unit Testing	Functional Testing, Asynchronous Testing
General info	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.	Vows is a testing framework for NodeJS applications. Vows supports Asynchronous BDD & continuous testing for two reasons first, reason is that node.js is asynchronous, and therefore our tests need to be, second,is to make test suites which target I/O libraries run much faster.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	N/A	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Wallaby.js can test front-end components and functionality	No
Server-side Allows testing the bahovior of a server-side code	Yes Wallaby.js can test server behaviour and functionality	Yes Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	No
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	No
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	N/A	Apache License 2.0
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)	By use of a third party library Jest works well with wallaby
Grouping Allows organizing tests in groups
