Specter vs PHPUnit comparison of testing frameworks
What are the differences between Specter and PHPUnit?

	Specter http://specter.sourceforge.net/	PHPUnit https://phpunit.de/
Programming language	.NET	PHP
Category	Acceptance Testing	Unit Testing
General info	Specter is a behaviour-driven development framework for .NET and Mono Specter enables behavior driven development (BDD) by allowing developers to write executable specifications for their objects, before actually implementing them, this is similar to test driven development however the different nomenclature makes it different from writing 'tests' for code that does not exist yet	PHPUnit is a unit testing framework for the PHP programming language PHPUnit is a programmer-oriented testing framework and is an instance of the xUnit architecture for unit testing frameworks.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It's an instance of the xUnit architecture for unit testing frameworks
Client-side Allows testing code execution on the client, such as a web browser	Yes Developers can create specfications of the expected front-end behaviours and test them	Yes It can perform Unit tests and can test various front-end components and behaviours
Server-side Allows testing the bahovior of a server-side code	Yes Yes developers can create specfications of the expected back-end behaviours and test these.	Yes By performing unit tests on singular back-end components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes By use of a setup code. The setup code consists of two Important template functions, the 'setUp()' function (called to create the objects to be tested) and 'tearDown()' function (called to cleanup the objects which you tested)
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.	N/A	Yes It does support group fixtures
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	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)	N/A	Yes One of its main features is that PHPUnit comes with out of the box support for Mock objects
Grouping Allows organizing tests in groups	Yes You can create your own test suites with specter	Yes It allows grouping of tests and by using the @group annotation one can tag a test to belong to one or more groups
