Apparent bug in VS2013: PrivateType.InvokeStatic RRS feed

  • Question

  • I've encountered what seems to be a bug in the PrivateType class. Specifically, it can't find private, static GENERIC methods. A tentative search on the internet seems to indicate that this has been an issue since VS2010. I'm hoping for official confirmation so I can stop searching.

    Toy example:

    class MyClass {
       private static bool Compare<T>( T a, T b ) { 
           return a.Equals(b); 
    ... test framework ...
    public void TestStuff() {
       PrivateType pt = new PrivateType( typeof(MyClass) );
       Type t = typeof(int);
       bool result = (bool)pt.InvokeStatic("Compare", 
               new Type[] {t, t}, 
               new object[] {1, 3}, 
               new Type[] {t} 

    The attempt to invoke should throw a System.ArgumentException.  The example is a distilled version of what I'm currently running.  Only the method name has been changed and none of the surrounding code is included.

  • Hi curds01,

    Just to make this issue clearly, do you mean that you want to test a private method in your unit test project, am I right? 

    As far as I know, it changed some features from the VS2010.

    Like this blog:

    How to test Private methods using Visual Studio’s testing framework

    In the higher VS version, Testing private methods can be done using the PrivateObject class.

    Best Regards,
