What are the differences between Arquillian and Specter?

Arquillian

http://arquillian.org/

Specter

http://specter.sourceforge.net/
Programming language

Java

.NET

Category

Intergration Testing, Functional Testing

Acceptance Testing

General info

Arquillian is an Open source framework for writing Integration and functional tests

Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well

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

Yes

It is a xUnit framework

No

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

Yes

You can perform unit tests on front-end components and functionality

Yes

Developers can create specfications of the expected front-end behaviours and test them
Server-side
Allows testing the bahovior of a server-side code

Yes

You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions

Yes

Yes developers can create specfications of the expected back-end behaviours and test these.
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

By use of extensions, for example you can use the Persistence extension to set database fixtures

N/A

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

N/A

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

Licence
Licence type governing the use and redistribution of the software

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

Arquillian supports mock object functionality you can use third party libraries

N/A

Grouping
Allows organizing tests in groups

Yes

Arquilian supports grouping of tests

Yes

You can create your own test suites with specter
