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)

PHPUnit is a unit testing framework for the PHP programming language

PHPUnit is a programmer-oriented testing framework and is an instance of the xUnit architecture for unit testing frameworks.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

It's an instance of the xUnit architecture for unit testing frameworks
Client-side
Allows testing code execution on the client, such as a web browser

Yes

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

Yes

It can perform Unit tests and can test various front-end components and behaviours
Server-side
Allows testing the bahovior of a server-side code

Yes

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

Yes

By performing unit tests on singular back-end components
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

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.

Yes

By use of a setup code. The setup code consists of two Important template functions, the 'setUp()' function (called to create the objects to be tested) and 'tearDown()' function (called to cleanup the objects which you tested)
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

Jest supports group fixtures

Yes

It does support 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.

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)

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.

Yes

One of its main features is that PHPUnit comes with out of the box support for Mock objects
Grouping
Allows organizing tests in groups

Yes

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

Yes

It allows grouping of tests and by using the @group annotation one can tag a test to belong to one or more groups
