I am learning unit testing and was requesting a sample c# code for the project https://github.com/alialavia/MSINet which will guide me on what to do.

What I have tried:

stilll can't determine which methods to include in test and which to leave out.

That code can't be unit tested, it is mainly static methods and no abstraction to decouple the code\logic from external dependencies such as msi.dll.

I was talking about the project (the one in github)

have you opened in visual studio?what about enumerate() in installproprty class.can't u test it

You can't test it because it calls MSI.EnumerateGUIDs which has a reliance on msi.dll and will enumerate the installed products on whatever PC it is on. Unit tests test logic and need to be self-contained. The only logic in that code is that a function called EnumerateGUIDs which is barely worth testing. It's also impossible to know what the method has done because you can't inject your own services\data into the class as it hasn't been written in a way that supports it. You can't test the results as what is the outcome? The outcome will vary on every machine it is ran on. Finally any enviornment you run those tests on will need msi.dll installed and working with consideration taken for the user account running the tests.

Have you already watched tutorials on main unit testing frameworks?
For example
MSDN: Walkthrough: Creating and Running Unit Tests for Managed Code[^]
MSDN: Unit Test Basics[^]
CodeProject: Creating Unit tests for your c# code[^]
NUnit - QuickStart[^]

It may be wiser to start from the beginning with existing learning material than to pick up a random project which, as it has been said, is not really testable.

Solution 2

There isn't a single method in that project that is unit testable in any practical sense. The entire project would need to be rewritten to accommodate testing.
