Unit Testing

General info

This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development)

Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.

csUnit is an open source unit testing tool for the .NET Framework

csUnit is designed to work with any .NET compliant language. It has specifically been tested with C#, Visual Basic .NET, Managed C++, and J#
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It is compatible with xUnit and supportsxUnit XML output

Yes

csUnit is an xUnit type testing framework and follows xUnit concepts
Client-side
Allows testing code execution on the client, such as a web browser

No

Yes

You can unit test front-end components of your applications with csUnit
Server-side
Allows testing the bahovior of a server-side code

Yes

Testdouble is primarily used to test server-side functions, behaviours and components

Yes

You can unit test back-end components of your applications with csUnit
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

csUnit has fixture methods such as setup and teardown methods
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

Yes

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.

N/A

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

Testdouble includes inbuilt support for mocking

You can write your own mock objects manually
Grouping
Allows organizing tests in groups

N/A

Yes

It contains recipes for combining several test assemblies into one test suite
