Peridot vs Cedar comparison of testing frameworks
What are the differences between Peridot and Cedar?

	Peridot http://peridot-php.github.io/	Cedar https://github.com/cedarbdd/cedar
Programming language	PHP	Swift
Category	Unit Testing	Unit Testing
General info	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	Cedar is a BDD-style testing for swift using Objective-C Cedar is a BDD-style Objective-C/Swift testing framework that has an expressive matcher DSL and convenient test doubles (mocks). It provides better organizational facilities than the tools provided by XCTest/OCUnit In environments where C++ is available, it provides powerful built-in matchers, test doubles and fakes
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Cedar is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end components can be tested with Peridot	Yes You can test front-end components and behaviour with Cedar, its language is biased towards describing the behavior of your objects.
Server-side Allows testing the bahovior of a server-side code	Yes Back-end componets and behaviours can be tested as small units	Yes You can test back-end components with a bias towards their expected behaviour. Cedar specs also allow you to nest contexts so that it is easier to understand how your object behaves in different scenarios
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Peridot has several methods that allow one to create and define fixtures	Yes Cedar has beforeEach and afterEach class methods which Cedar will look for on every class it loads. You can add these onto any class you compile into your specs and Cedar will run them
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 There are methods to create group fixtures in Peridot	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	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)	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	Yes Cedar contains inbuilt mock/test double functionality
Grouping Allows organizing tests in groups	Yes By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.	Yes Cedar supports shared example groups. You can declare them in one of two ways: either inline with your spec declarations, or separately.
