General info

PhpSpec is a testing tool based on the concept of emergent design using specification

PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line

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

No

No

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

Yes

By testing your PHP classes that run your front-end

Yes

Turnip can perform end-to-end tests therefore test front-end components and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

You can use PHPSpec to test your PHP classes that run your back-end

Yes

Turnip is used to test server-side behaviour and components
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

You can define fixtures

No

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 define group fixtures

No

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

There are methods that act as generators

No

Licence
Licence type governing the use and redistribution of the software

Free

MIT License

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

It has built in support for Mocks

Yes

By intergrating with RSpec turnip has access to the rspec-mocks gem
Grouping
Allows organizing tests in groups

In PHPspec, you can group specification files by a certain namespace in a suite

Yes

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