Instance Method Details

#and_raise(exception = Exception) ⇒ Object

:call-seq:

and_raise()
and_raise(Exception) #any exception class
and_raise(exception) #any exception object

Warning

When you pass an exception class, the MessageExpectation will raise an instance of it, creating it with new. If the exception class initializer requires any parameters, you must pass in an instance and not the class.
