Unit Testing, Intergration Testing

General info

TickSpec is a lightweight Behaviour Driven Development (BDD) framework for .Net

With TickSpeck you can describe behaviour in plain text using the Gherkin business language, execute the behaviour against matching F# 'ticked' methods, or attribute-tagged C# or F# methods, run via your normal test runners or plugins and set breakpoints in the scenarios, step definitions or your code and go (setting breakpoints in the Gherkin is currently not supported in .NET Standard version)

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.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

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.
Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can test front-end behaviour by creating feature specifications for front-end behaviour

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.
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test back-end code by creating feature specifications to test back-end behaviour

Yes

You can test server-side behaviour with Rspec
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Fixtures are available or are derived from the class FeatureFixture

Yes

RSpec does contain fixture methods
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

TickSpec contains group fixtures

Yes

Group fixture methods are supported
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

Yes

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

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

By using a third party mocking library like moq

Yes

Available through rspec-mocks gem.
Grouping
Allows organizing tests in groups

Yes

You can create test suites with TickSpec

Yes

Allows declaring example groups and contexts.
