Assert.IsTrue(ThrowsException(() => object.Method()));

While reading this post, I came across an interesting line of code:

    1: Assert.IsTrue(ThrowsException<UpdateException>(() => rb.Update(b2)));

    2:  

    3: ThrowsException<E> is:

    4:  

    5:      private static bool ThrowsException<E>(Action f) where E : Exception

    6:      {

    7:             try

    8:             {

    9:                 f();

   10:             }

   11:             catch (E)

   12:             {

   13:                 return true;

   14:             }

   15:             catch

   16:             {

   17:             }

   18:  

   19:             return false;

   20:      }

Clever!
