General info

QUnit is a JS Unit testing framework.

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

NUnit is an open-source unit testing framework for Microsoft .NET.

NUnit was Initially ported from JUnit. Tests can be run from a console runner, within Visual Studio through a Test Adapter or through 3rd party runners. Tests can be run in parallel and has Strong support for data driven tests. Unit supports multiple platforms including .NET Core, Xamarin Mobile, Compact Framework and Silverlight.
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

Nunit is one of many programs in the xUnit family
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

You can test front-end components with NUnit since it is a Unit testing framework the application is isolated into diverse modules which are tested independently
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

You can test back-end components with NUnit, it is a Unit testing framework hence the application is isolated into diverse modules which are tested independently
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

NUnit contains the fixture methods SetUp to initialize your test environment and TearDown method to destroy a test environment
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

Group fixtures are available in NUnit
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

You can create mock objects using the third party library moq
Grouping
Allows organizing tests in groups

Yes

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

Yes

You can group tests into suites with NUnit
