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

Doctest is an inbuilt test framework for Python

Doctest is a test framework that comes prepackaged with Python. It is a simple library with a functionality that makes it possible to search for pieces of text that look like interactive Python sessions and executes these sessions to see if they work exactly as shown.
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

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

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

Lacks fixture management which can make writing tests harder
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

Lacks fixture management
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

N/A

Licence
Licence type governing the use and redistribution of the software

Free

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

A good external library for using Mocks with Doctest is minimocks
Grouping
Allows organizing tests in groups

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

Yes

One can group tests
