Hound vs testdouble.js comparison of testing frameworks
What are the differences between Hound and testdouble.js?

	Hound https://github.com/HashNuke/hound	testdouble.js https://github.com/testdouble/testdouble.js
Programming language	Elixir	JavaScript
Category	Browser Automation, Intergration Testing	Unit Testing, Intergration Testing
General info	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	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is compatible with xUnit and supportsxUnit XML output
Client-side Allows testing code execution on the client, such as a web browser	Yes Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver	No
Server-side Allows testing the bahovior of a server-side code	N/A	Yes Testdouble is primarily used to test server-side functions, behaviours and components
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.	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 Yes, through the use of a third party library like Mockery	Yes Testdouble includes inbuilt support for mocking
Grouping Allows organizing tests in groups	N/A	N/A
