  •  It’s a unit-testing library that functions with any .Net Language. 
  • Version 2.0 is the recent development release and is the fourth massive update of this xUnit. It is, however, considered to be a necessary testing apparatus for Microsoft.NET, which primarily comes from Junit.
  • It’s entirely written in C# and was rewritten completely to realize the benefits of numerous .NET language features.

2. State the advantages of the NUnit Test.

The interviewer still continues to test your overall understanding of the NUnit test. Highlighted below are some merits of the NUnit Test

  • it’s entirely written in C# and massively rebuilt to realize the advantage of numerous .NET language capabilities.
  • NUnit is a framework for robotizing unit testing for all .NET languages 
  • NUnit includes xUNit support for every test that was written in a .NET supported language like C#, VB.NET, VC, J#, and others.
  • It’s an open-source testing framework for every .NET project.
  • NUnit provides a class library with specific classes, operations, and attributes to assist in creating test scenarios
  • NUnit was conventionally adapted from Junit which is a cross-platform unit for testing framework.
  • NUnit does not produce its own test scripts.

3. Mention the  core features of NUnit Test

Ans:  Highlighted below  are the core features of NUnit test: 

  • NUnit enables users to have configurations for their tests that stand out from the ones used in development if their application stores settings in configuration files.
  • NUnit has support for tests that are classified as multiple assemblies also designing and administering tests as NUnit projects. 
  • There is the provision of  Visual Studio Support for users running NUnit on a laptop or PC using visual studio.
  • Statements in source code are assertions and describe the correct operation of the application.

4. Explain about  NUnit test Framework

State that;

  • NUnit is unit-testing structure for.NET applications that segregate the current app into different modules. 
  • Each module is individually scrutinized to ensure that the objective is met
  • The NUnit framework supports numerous properties used in unit tests. Ignore methods, expected exceptions,Test -Fixtures, and Test methods are all defined.

5. How is NUnit used in unit testing?

NUnit is used in unit testing with a test method. A test method is a method with the test parameter. We use the file to run dot net tests which establish the tests and the object library then run the tests. We run the assertions on the NUnit test server since it has the program access point.

6. What languages does NUnit support?


NUnit is presently developed in C#. C# is an object-oriented programming language that incorporates the ability and  capability of C++ with the security of use of Visual Studio. NUnit is among the  xUnit library of testing frameworks.

7. Explain about NUnit console runner.

State that;

  • NUnit-console.exe can be described as a word-based runner that can  be used to run all of your tests without the need of a green/red/yellow signal of accomplishment. 
  • It can be utilised to robotized  tests and incorporate with other apps

8. Describe the pairwise attribute


 The Pairwise Attribute is used to test and  to tell NUnit that every possible set of values should be employed when generating test cases. It’s a prevalent method deployed to avoid the sequential inflation of test cases since more than two variables are involved.

9. What do you understand about  Attributes in NUnit tests?


The conventional method of defining tests in NUnit was dependent on naming and inheritance factors. NUnit uses optimistic attributes for this function since version 2.0.

The developer can make use of inheritance in different ways since NUnit test components do not inherit from a platform class. The names selected can be fully focused on demonstrating the test’s objective Because there isn’t arbitrary naming criteria for tests

The NUnit.Framework domain comprises all NUnit properties. The app must indicate the platform assembly, NUnit.framework.dll.

10. Is NUnit a GUI runner?


NUnit.exe is visual running software that presents the tests in an interceptor web browser. It also gives a visual presentation of whether they passed or not. It allows users to run particular tests or suites manually. Interestingly, it reloads itself as users change and reload code.

11. Explain the NUnit Extensibility in detailed information

Ans: NUnit extensibility ranges in a variety of different ways.

Developers made Custom Asserts to define the tests that concern their projects. They are prevalent enhancements to the NUnit framework I.e the fraction of NUnit that is necessary for tests.

NUnit Addins are needed for the extension of functionalities provided within NUnit. Presently, The Addin technique only accepts changes to the NUnit core which is the component of NUnit that produces and uses test suites. 

 However, the API use enables the client-side of NUnit kike  the GUI, to be lengthened in the future.
