General info

Domain Specific Language (DSL) testing solution for Ruby code

It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.

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

Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.

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

Yes

RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.

Yes

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

Yes

You can test server-side behaviour with Rspec

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

Yes

RSpec does contain fixture methods

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.

Yes

Group fixture methods are supported

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.

Yes

RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder

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

Available through rspec-mocks gem.

Yes

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

Yes

Allows declaring example groups and contexts.

Yes

You can group tests into suites
