Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth, *args, &block) ⇒ Object

If the test framework’s helper module doesn’t provide support for a given test-related method, return a friendly message. Raise NoMethodError for any other failed calls.
