General info

Spinach is a BDD framework on top of Gherkin

Spinach is a high-level BDD framework that leverages the Gherkin language to help define executable specifications of your application or library's acceptance criteria.

wru is an essential general purpose test framework compatible with web environment, node.js, Rhino, and now PhantomJS too.

wru is compatible with basically all possible browsers out there included IE5.5, IE6, IE7, IE8, IE9, IE10, Chrome, Firefox, Safari, Webkit based, Mobile Browsers, and Opera. On server side wru is compatible with latest node.js, Rhino, PhantomJS, and JavaScriptCore versions.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

Wru is compatible with xUnit
Client-side
Allows testing code execution on the client, such as a web browser

N/A

Yes

Wru tests front-end components and functions, it is compatible with HTML and runs on probably all browsers
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test any server-side behaviour with Spinach

Yes

It is used to test back-end components and behaviour and runs in server environments
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

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.

No

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.

Yes

Spinach has inbuilt generator methods
