Spinach

Programming language

JavaScript

Ruby

Category

Functional Testing, Asynchronous Testing

Acceptance Testing

General info

Vows is a testing framework for NodeJS applications.

Vows supports Asynchronous BDD & continuous testing for two reasons first, reason is that node.js is asynchronous, and therefore our tests need to be, second,is to make test suites which target I/O libraries run much faster.

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.
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

No

N/A

Server-side
Allows testing the bahovior of a server-side code

Yes

Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions

Yes

You can test any server-side behaviour with Spinach
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

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.

No

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

Spinach has inbuilt generator methods

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

Spinach can access the rspec-mocks methods
Grouping
Allows organizing tests in groups

Yes

Spinach Integrates with your RSpec test suite which allows declaring example groups and contexts.
