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

	Cedar https://github.com/cedarbdd/cedar	AVA https://github.com/avajs/ava
Programming language	Swift	JavaScript
Category	Unit Testing	Unit Testing, Intergration Testing
General info	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	Futuristic, new, fast and concurrent JavaScript test runner with simple test syntax AVA is a test runner for Node.js with a concise API, detailed error output. JS is a single-threaded but Node.JS is a parallel due to it's async behaviour. Ava leverages that and it can run tests concurrently
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Cedar is an xUnit style framework	No However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components and behaviour with Cedar, its language is biased towards describing the behavior of your objects.	Yes You can write tests for the DOM with Ava, testing front-end components is easy with Ava
Server-side Allows testing the bahovior of a server-side code	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	Yes Ava utilizes the async I/O nature of Node and runs concurrent tests on NodeJs applications' back-endsA node server can have its endpoints tested with Ava
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	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	Yes Using Ava's ava-fixture library it supports 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 Ava has support for group fixtures
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)	Yes Cedar contains inbuilt mock/test double functionality	AVA has no mocking built in, to mock functions you can use third party libraries like Sinon.js.
Grouping Allows organizing tests in groups	Yes Cedar supports shared example groups. You can declare them in one of two ways: either inline with your spec declarations, or separately.	No There is no support for grouping tests
