test private generic static method

0 votes
Hi there,

I want to test a private static method and I simply do not find a way to do it. :(

The setup is an extension class which implements a couple of extension methods and these extension methods use private (to the extension class) methods to accomplish there jobs. And I want to test them. However some of which are generic and return a value. And I want to test the returned value.
Just to show the general idea: 
public static class Extensions
{
   public static DoSomting (this foo, int x)
   {
        DoSomethingElse<int> (x);
        return x*2;
   }

   // this method shall be tested and the return value shall be checked
   private static T DoSomethingElse<T> (T x)
   {
       if(typeof(t)==typeof(int))
          return x*2;
       return default(T)
   }
}


I have searched the documentation and was not able to find help. :(

Could anyone give me a hint?

Thank's in advance.

Hi,

I am not quite sure i understand what you are trying to accomplish here :?

Are you trying to invoke DoSomethingElse?
Are you trying to invoke DoSomting and fake DoSomethingElse?

Hi Peter,

Invoking private generic methods is not currently supported in our API...
If all you want to do is invoke that private method (without faking it), please consider simply using reflection. see this Stack Overflow answer:

http://stackoverflow.com/questions/2325 ... ric-method

Another possibility - you may make that method Internal instead of private. Sometimes it is forgivable...

Aside from the technical issue here, without me knowing what it is you are actually testing, I do recommend focusing your tests on the public methods of your classes, using them to invoke the private methods in the process.
That way the tests are less dependent on the implementation details of your product.

Good luck,

Thank you for hint!

And also for the advise. I will think my testing strategy over.
