Specter

Programming language

JavaScript

.NET

Category

Unit Testing

Acceptance Testing

General info

Standalone test stubs and mocks for JavaScript. Works with any unit testing framework.

Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.

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

Compatible

No

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

Yes

Sinon.js is a good library for unit testing your front-end code and has cross browser support

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

Sinon.js can run on node.js to test back-end components and server-side behaviour

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

N/A

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.

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.

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

SinonJS is basically a library that we can use to create object mocks for unit testing

N/A

Grouping
Allows organizing tests in groups

Yes

You can create your own test suites with specter
