General info

QUnit is a JS Unit testing framework.

QUnit is especially useful for regression testing of jQuery, jQuery UI and jQuery Mobile projects

Quick is a Swift (and Objective-C) testing framework.

Quick is a behavior-driven development framework for Swift and Objective-C that is inspired by RSpec, Specta, and Ginkgo. Quick comes bundled with Nimble a matcher framework for your tests.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

Yes, it is a xUnit style framework

Yes

Yes, it is an xUnit style test framework
Client-side
Allows testing code execution on the client, such as a web browser

Yes

QUnit is commonly used by jQuery, jQuery UI and jQuery Mobile It can test front-end components and functionality

Yes

Developers can test front-end behaviour and components by defining front-end feature specifications
Server-side
Allows testing the bahovior of a server-side code

Yes

Qunit can test any JavaScript code(including itself), this includes server-side components and functionality. Supports NodeJs

Yes

Developers can test back-end behaviour and components by defining back-end feature specifications
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

By using the qunit-fixture element which is a container for some HTML that your tests can assert against.

Yes

Quick contains fixture methods setup() and teardown() for setting up and destroying test environments
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

You can group fixtures together with QUnit

Yes

Yes, example groups (logical groupings of examples/tests) can share setup and teardown code
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)

You can use third party libraries like jQuery's Mockjax plugin

Yes

Yes, developers can create mock objects with Quick using the Cuckoo library
Grouping
Allows organizing tests in groups

Yes

You can use the QUnit.module() function to group tests together

Yes

In Quick test suites are named Specs, and every test suite you create starts off with a class inheriting from QuickSpec includes a main method, spec() which contains all the test cases.
