What are the differences between and Cucumber?

Programming language




Unit Testing

Acceptance Testing

General info is aUnit testing framework for C# and .NET is a free, open source, community-focused unit testing tool for the .NET Framework. It is used to test C#, F#, VB.NET and other .NET languages. and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,

An automation tool for Behavior-Driven Development

The specifications are written in plain texts, which allows them to be easily understandable for all stakeholders. Cucumber Framework also supports languages beyond Ruby e.g. Java, JavaScript and Scala.
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes is part of the xUnit family of frameworks


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


You can test various front-end components independently since it is a Unit testing framework


You can test the front-end part like the GUI using cucumber and selenium, they integrate well to test your front-end.
Allows testing the bahovior of a server-side code


You can test various back-end components independently since it is a Unit testing framework


You can test back-end components such as APIs using rest & soap clients, and databases using whatever client libraries were provided by the libraries that existed in those stacks
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


It contains class fixtures which are setup once pertest class

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.

Yes contains collection fixtures which allow you to share context among many tests


Using the cucumber extension aruba you can create fixures in two steps: 1.Create a fixtures-directory; 2.Create fixture files in this directory
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.


You can group your fixtures inside your fixtures directories

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)


By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)
Allows organizing tests in groups


Cucumber allows the use of tag Cucumber feature files or individual tests to group tests. Then, you can pass a Cucumber tagged expression at test execution that specifies the tag (grouped) tests to run.
