What are the differences between Wallaby and Hound?

	Wallaby https://github.com/elixir-wallaby/wallaby	Hound https://github.com/HashNuke/hound
Programming language	Elixir	Elixir
Category	Intergration Testing, Browser Automation	Browser Automation, Intergration 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	Elixir library for browser automation and writing intergration tests It is a front-end testing library that has support for: Selenium (Firefox, Chrome), ChromeDriver and PhantomJs. Also supports JavaScript applications and retries tests a few times before reporting errors
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	Yes Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver
Server-side Allows testing the bahovior of a server-side code	N/A	N/A
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	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.	N/A	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	Yes Not inbuilt but by use of a third party library like ExopData
Licence Licence type governing the use and redistribution of the software	MIT License	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 Available through third party libraries like Mock and Mockery	Yes Yes, through the use of a third party library like Mockery
Grouping Allows organizing tests in groups	N/A	N/A
