Unit Testing

General info

A Unit Testing framework focused on simplicity

This is a Unit test framwork especially designed for the React.JS, Babel, TypeScript, Node, React, Angular and Vue projects. It usually worked with Enzyme(Integration testing) 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,
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
Allows testing code execution on the client, such as a web browser


You can easily test methods, properties, UI element actions and other front-end functionalities


You can test various front-end components independently since it is a Unit testing framework
Allows testing the bahovior of a server-side code


Back-end server behaviour also can be tested with Jest much in the same way as the front-end tests.


You can test various back-end components independently since it is a Unit testing framework
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


Fixtures are supported, Jest has many helper functions such as: BeforeEach and afterEach If you have some work you need to do repeatedly for many tests, beforeAll and afterAll if you only need to do setup once, at the beginning of a file.


It contains class fixtures which are setup once pertest class
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.


Jest supports group fixtures

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


Licence type governing the use and redistribution of the software

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)

Jest uses a custom resolver for imports in your tests making it simple to mock any object outside of your test’s scope. You can use mocked imports with the rich Mock Functions API to spy on function calls with readable test syntax.

Allows organizing tests in groups


You can declare as many test suites as you want. Grouping of tests together is done using a describe block
