General info

Intern is minimal test system for JavaScript designed to write and run consistent.

Intern is a complete test system for JavaScript designed to help you write and run consistent, high-quality test cases for your JavaScript libraries and applications. Using Intern we can write tests in JavaScript and TypeScript using any style like TDD, and BDD. Intern can run unit tests in most browsers that support ECMAScript

Peridot is a lightweight, extensible testing framework for PHP

It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

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

Yes

Intern is a complete test system for JavaScript It Runs in the browser and can test any front-end component and functionality

Yes

Front-end components can be tested with Peridot
Server-side
Allows testing the bahovior of a server-side code

Yes

Since it is a complete testing system that can test any type of JavaScript code, it can test server-side behaviour and components as well

Yes

Back-end componets and behaviours can be tested as small units
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

Peridot has several methods that allow one to create and define 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.

N/A

N/A

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)

Intern uses the Dojo Toolkit’s AMD loader. To mock, you should be able to just use the standard AMD 'map' feature, else you can use third party libraries like sinon.js

Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with
Grouping
Allows organizing tests in groups

Yes

You can group tests into Suites which may be specified as file paths or using glob expressions, there is typically one top-level suite per module.

Yes

By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.
