org.fest.reflect.method.MethodName
Understands the name of a method to invoke using Java Reflection.
The following is an example of proper usage of this class:
// Equivalent to call 'person.setName("Luke")'method
("setName").withParameterTypes
(String.class) .in
(person) .invoke
("Luke"); // Equivalent to call 'person.concentrate()'method
("concentrate").in
(person).invoke
(); // Equivalent to call 'person.getName()' String name =method
("getName").withReturnType
(String.class) .in
(person) .invoke
