Several C # Open-Source testing tools

Nunit
Nunit is a unit test framework that can be used in all languages that comply with. NET Framework Standards. Nunit was originally transplanted from JUnit. Nunit is fully written in C # and is designed to take into account the features of most. NET languages, such as custom attributes and other reflection features. (Official)

Nmock
Nmock is a dynamic proxy-based mock simulation object class library on the. NET platform for C # development. The mock object makes the test simpler. It tests a single component or a single class without the actual implementation of all other components. That is to say, we can only test a class, which is easier to identify bugs than to test a complete object relationship tree. Mock objects are generally used for testing-driven development.

Testdriven. net
Testdriven. Net is a test plug-in that seamlessly integrates with Visual Studio. NET. It can work closely with nunit, mbunit, and team system. (Official)

Rhino. mocks 
Rhino. mocks is derived from easymock. net. It tries to provide a simpler method to create and use mock objects and give you better refactoring support. It combines easymock. NET and nmock. (Official)

Dot netunit 
Dot netunit implements the xunit Testing Framework and is a unit testing component on the. NET platform. (Official)


Easymock. net 
Easymock. Net is a set of class libraries from easymock implemented by Java to a portable version of the. NET platform. It provides a simple method to simulate interfaces and remote objects. (Official)

Dotunit 
Dotunit is a testing framework for JUnit porting to the Microsoft. NET platform. It can achieve automated testing. (Official)

Nunitforms 
Nunitforms is an extension of nunit. It provides unit testing and stress testing for Windows Forms applications and can be easily used for automated testing for your Windows Forms classes. (Official)
