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.

Fixie is a .NET test framework similar to NUnit and xUnit

Fixie allows test methods to be created and executed like other test frameworks, but takes a takes a conventions-based approach, which is a benefit as we do not need to use attributes to mark classes and methods as tests
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

fixie is an xUnit type testing framework
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

You can unit test front-end components of youra pplications with fixie
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

You can unit test back-end components of your applications with fixie
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.

Yes

Yes, fixie has fixture methods for setting up tests and at the end of tests to destroy them
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

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

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

Specflow intergrates well with mock to give it excellent mocking capabilities

N/A

Grouping
Allows organizing tests in groups

Yes

You can create test suites with specflow

Yes

You can group tests into suites
