General info

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.

Elixir library for browser automation and writing intergration tests

It is a front-end testing library that has support for: Selenium (Firefox, Chrome), ChromeDriver and PhantomJs. Also supports JavaScript applications and retries tests a few times before reporting errors
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It's an instance of the xUnit architecture for unit testing frameworks

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

It can perform Unit tests and can test various front-end components and behaviours

Yes

Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver
Server-side
Allows testing the bahovior of a server-side code

Yes

By performing unit tests on singular back-end components

N/A

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

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)

N/A

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

It does support group fixtures

N/A

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

Yes

Not inbuilt but by use of a third party library like ExopData

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

One of its main features is that PHPUnit comes with out of the box support for Mock objects

Yes

Yes, through the use of a third party library like Mockery
Grouping
Allows organizing tests in groups

Yes

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

N/A
