Instance Method Details

#check_exception(exception = Exception) ⇒ Object

This method creates a new ‘Speck::Check` initialized to pass if the receiver can be executed without `exception` being raised, or fail if the receiver raises `exception` when raised.

The passed exception object will be ‘rescue`d from within the block, but any other exception raised by the block will not be caught.
