What are the differences between Hound and Peridot?

	Hound https://github.com/HashNuke/hound	Peridot http://peridot-php.github.io/
Programming language	Elixir	PHP
Category	Browser Automation, Intergration Testing	Unit 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	Peridot is a lightweight, extensible testing framework for PHP It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable
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 Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver	Yes Front-end components can be tested with Peridot
Server-side Allows testing the bahovior of a server-side code	N/A	Yes Back-end componets and behaviours can be tested as small units
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes Peridot has several methods that allow one to create and define fixtures
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	Yes There are methods to create group fixtures in Peridot
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	N/A
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	Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with
Grouping Allows organizing tests in groups	N/A	Yes By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.
