General info

Turnip is a Gherkin extension for RSpec

Turnip is an open source Ruby gem that provides a platform for acceptance tests.It combines Gherkin, a language defined by the Cucumber Behavior-Driven Development (BDD) tool to express requirements, and RSpec, an open source BDD tool for Ruby developers.

XCTest is the default testing framework for unit tests, performance tests, and some level of UI tests for iOS apps.

XCTest framework is a testing framework that enables developers write basic unit tests, performance tests, and some level of UI tests for iOS apps.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

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

Yes

Turnip can perform end-to-end tests therefore test front-end components and functionality

Yes

Developers can test individual front-end components with XCTest
Server-side
Allows testing the bahovior of a server-side code

Yes

Turnip is used to test server-side behaviour and components

Yes

Yes, developers can test individual back-end components with XCTest
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

Yes

XCTest contains setup() and teardown() fixture methods 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.

No

Yes

Group fixtures are available in XCTest
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.

No

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

By intergrating with RSpec turnip has access to the rspec-mocks gem

Yes

You can create protocol mocks and class mocks with libraries such as MockFive or Cuckoo
Grouping
Allows organizing tests in groups

Yes

Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.

Yes

Developers can define test suites from the XCTestSuite class
