General info

This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development)

Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.

LightBDD is a BDD test framework that allows you to create easy to read and maintainable tests

LightBDD is a BDD test framework offering ability to write tests that are easy to read, easy to track during execution and are summarized in user friendly reports. It also allows developers to use all of the standard development tools to maintain them
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It is compatible with xUnit and supportsxUnit XML output

No

No, but it is Integrated with xUnit frameworkslike NUnit, xUnit, MsTest.TestFramework and Fixie.
Client-side
Allows testing code execution on the client, such as a web browser

No

Yes

You can test front-end behaviour using lightBDD
Server-side
Allows testing the bahovior of a server-side code

Yes

Testdouble is primarily used to test server-side functions, behaviours and components

Yes

You can test back-end behaviour/functionality using lightBDD
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

Fixtures are available through the FeatureFixture class.
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

Yes

Group fixtures are available in lightBDD through the FeatureFixture class
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

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

Testdouble includes inbuilt support for mocking

Yes

Mocking is available through the use of third party libraries like moq
Grouping
Allows organizing tests in groups

N/A

Yes

You can group tests into suites
