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

	Wallaby https://github.com/elixir-wallaby/wallaby	Vows http://vowsjs.org/
Programming language	Elixir	JavaScript
Category	Intergration Testing, Browser Automation	Functional Testing, Asynchronous Testing
General info	Library for end-to-end intergration testing for Elixir apps Wallaby supports concurrent feature testing (i.e multiple tests can run concurrently) as well as browser management	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.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes It works well for automated E2E testing; Wallaby also has an experimental Chrome Driver that works well	No
Server-side Allows testing the bahovior of a server-side code	N/A	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	MIT License	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)	Yes Available through third party libraries like Mock and Mockery
Grouping Allows organizing tests in groups	N/A
