StoryPlayer vs RSpec comparison of testing frameworks
What are the differences between StoryPlayer and RSpec?

	StoryPlayer http://datasift.github.io/storyplayer/	RSpec https://rspec.info
Programming language	PHP	Ruby
Category	Unit testing, Functional Testing	Unit Testing, Intergration Testing
General info	Storyplayer is a full-stack testing framework Storyplayer follows a TDD testing approach and makes it possible to write end-to-end tests for an entire platform. It has support for creating and destroying test environments on demand	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.
Client-side Allows testing code execution on the client, such as a web browser	Yes By running a 'user story' which is a simple statement that describes one action, and who can perform that action then record of the conversations about this action, this is how you would test front-end functionality and components	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.
Server-side Allows testing the bahovior of a server-side code	Yes By writing a 'service story' which is a 'userstory' except it describes the behaviour of your back-end systems	Yes You can test server-side behaviour with Rspec
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Storyplayer has fixtures that can create and destroy test environments on demand	Yes RSpec does contain fixture methods
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.	Yes It supports group fixtures	Yes Group fixture methods are supported
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 foreach(hostWithRole()) is a generator allows you to easily perform actions against all hosts in your test environment without having to hard-code the host IDs or hostnames into your story.	Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder
Licence Licence type governing the use and redistribution of the software	New BSD 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)	By using a library like mockery which intergrates well with storyplayer	Yes Available through rspec-mocks gem.
Grouping Allows organizing tests in groups	Yes Storyplayer’s job is to execute a suite of functional tests	Yes Allows declaring example groups and contexts.
