Pascal Schumacher updated LANG-1195:
------------------------------------
    Description: 
Currently, MethodUtils is restricted to finding and invoking accessible 
methods.  Frequently, developers have a need to test 'private' methods.  What I 
see is that they escalate access to 'protected' in order to more easily provide 
test coverage for these methods.  From a design perspective, this is bad.  

I propose to enhance MethodUtils so that it can easily invoke private methods.  
I'm not suggesting that developers should do this in production code, merely 
test code.  Much as FieldUtils provides access to private fields via the 
'forceAccess' overload on many of its methods.  I've copied a utility like this 
around for years.  It would be much more convenient to simply include it with 
Commons Lang.  I propose adding the following overloads to existing methods on 
MethodUtils.
{code}
public static Object invokeMethod(final Object object, final boolean 
forceAccess, final String methodName) 
throws NoSuchMethodException, IllegalAccessException, InvocationTargetException
                        
public static Object invokeMethod(final Object object, final boolean 
forceAccess, final String methodName, Object... args)
throws NoSuchMethodException, IllegalAccessException, InvocationTargetException
                        
public static Object invokeMethod(final Object object, final boolean 
forceAccess, final String methodName, Object[] args, Class<?>[] parameterTypes)
throws NoSuchMethodException, IllegalAccessException, InvocationTargetException
{code}
Furthermore, I propose the following new method for finding private methods 
patterned after getAccessibleMatchingMethod:
{code}
public static Method getMatchingMethod(final Class<?> cls, final String 
methodName, final Class<?>... parameterTypes)
{code}
I have, in fact, forked your github repository and coded this enhancement as 
well as unit test coverage for this.  I'll add a comment to this ticket once I 
get a branch in my fork created and the enhancement checked in.  Every effort 
has been made to adhere to your coding conventions.  Thanks for looking at this.
