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

	AVA https://github.com/avajs/ava	Tape https://github.com/substack/tape
Programming language	JavaScript	JavaScript
Category	Unit Testing, Intergration Testing	Unit Testing, Intergration Testing
General info	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	tap-producing test harness for node and browsers. Tape API is a small superset of the node core assert module
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML	Yes It does support xUnit output
Client-side Allows testing code execution on the client, such as a web browser	Yes You can write tests for the DOM with Ava, testing front-end components is easy with Ava	Yes You can write tests for any part of your front-end code to test any component or functionality
Server-side Allows testing the bahovior of a server-side code	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	Yes With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Using Ava's ava-fixture library it supports fixtures	No Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality
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 Ava has support for group fixtures	No
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	No
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)	AVA has no mocking built in, to mock functions you can use third party libraries like Sinon.js.	No Tape is a minimalistic framework that provides only essential features to make your assertions about your code
Grouping Allows organizing tests in groups	No There is no support for grouping tests	No Tape contains only the essential features for making assertions on your code
