General info

SpecFlow is a test automation solution for .NET

SpecFlow is a test automation solution for .NET which follows the BDD paradigm, and is part of the Cucumber family. SpecFlow tests are written with Gherkin, using the official Gherkin parser which allows you to write test cases using natural languages and supports over 70 languages.

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

No

Yes

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

Yes

Front-end behaviour is tested. With specflow specifications of the expected behaviours are made and specflow tests against this

Yes

Sinon.js is a good library for unit testing your front-end code and has cross browser support
Server-side
Allows testing the bahovior of a server-side code

Yes

Back-end behaviour is tested. Specifications of the expected behaviours are made and specflow tests against them

Yes

Sinon.js can run on node.js to test back-end components and server-side behaviour
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

BeforeTestRun and AfterTestRun are executed once for each thread which is a limitation of the current architecture.

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.

Yes

SpecFlow contains a generator component. The SpecFlow IDE integration tries to locate the generator component in your project structure, in order to use the generator version matching the SpecFlow runtime in your project

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

Specflow intergrates well with mock to give it excellent mocking capabilities

Yes

SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping
Allows organizing tests in groups

Yes

You can create test suites with specflow
