What are the differences between and AVA?

Programming language




Unit Testing

Unit Testing, Intergration Testing

General info is aUnit testing framework for C# and .NET is a free, open source, community-focused unit testing tool for the .NET Framework. It is used to test C#, F#, VB.NET and other .NET languages. and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,

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
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes is part of the xUnit family of frameworks


However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML
Allows testing code execution on the client, such as a web browser


You can test various front-end components independently since it is a Unit testing framework


You can write tests for the DOM with Ava, testing front-end components is easy with Ava
Allows testing the bahovior of a server-side code


You can test various back-end components independently since it is a Unit testing framework


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
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


It contains class fixtures which are setup once pertest class


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.

Yes contains collection fixtures which allow you to share context among many tests


Ava has support for group fixtures
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.

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.
Allows organizing tests in groups


There is no support for grouping tests
