General info

xUnit.net is aUnit testing framework for C# and .NET

xUnit.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. xUnit.net and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,

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

xUnit.net is part of the xUnit family of frameworks

Yes

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

Yes

You can test various front-end components independently since it is a Unit testing framework

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

You can test various back-end components independently since it is a Unit testing framework

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

It contains class fixtures which are setup once pertest class

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

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

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)

Yes

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

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.
